Guard load arrest device being used to protect a drone from falling during testing.

Drone Testing with Guard Load Arrestors

Problem:
When developing next-gen payload drones designed to carry heavy loads, safety during testing is critical. Our client faced the challenge of preventing their high-value drones from hitting the floor during unexpected failures. Uncontrolled movements due to motor malfunctions posed significant risks to both the drones and the testing personnel.

Solution:
Enter the Guard Load Arrestor! By fitting this device above the drone's take-off position, we've provided a reliable safety net. The Guard Load Arrestor's extendable cable, attached to the drone with a shackle, follows its movements seamlessly. If the drone exceeds the Guard's maximum speed, the brake locks, catching any uncontrolled movement. This system not only prevents crashes but also ensures the safety of the testing personnel.

✅ Safer testing environments
✅ Protection for high-value drones
✅ Reduced risk of accidents

Case Study: Galvanising Plants

Using a load arrestor in a galvanising plant can enhance safety by preventing accidents and injuries related to the handling of heavy loads, such as metal objects, being moved during the galvanizing process. A load arrestor, also known as a 'Guard', 'load arrest device' or 'load arrester', is a device designed to limit the movement of a load in the event of a failure in the lifting equipment, normally a hoist. Here's how load arrestors can be beneficial in a galvanising plant:

  • Preventing Accidents: Load arrestors provide an additional layer of safety by restricting uncontrolled movements of heavy loads. In the galvanizing process, large metal objects are lifted and moved, which can pose a significant risk if the lifting equipment fails. A load arrestor can prevent these loads from falling and causing accidents.
  • Emergency Stop: Load arrestors are equipped with an emergency stop mechanism that quickly stops the movement of a load in case of an accidental fall, such as when the lifting equipment malfunctions. This can prevent further accidents and injuries.
  • Reduction of Impact Forces: Load arrestors are designed to absorb and dissipate energy, reducing the impact forces that would otherwise occur is the emergency brake engages. This is particularly important in preventing damage to both the load and the surrounding equipment.
  • Worker Safety: Load arrestors can improve the safety of workers involved in the lifting and movement of heavy loads. By providing a controlled arrest of the load's movement, the risk of sudden load drops or swings is minimized.

When implementing load arrestors in a galvanizing plant, consider the following:

  • Proper Installation: Load arrestors should be installed according to the manufacturer's guidelines and recommendations.
  • Regular Maintenance: Like all safety equipment, load arrestors need regular inspections and maintenance to ensure they are in proper working condition. This is especially important in galv. plants, where vapours create a more corrosive environment.
  • Compatibility: Ensure that the load arrestors are compatible with the specific loads used in your galvanizing plant.
  • Compliance: Check if there are any relevant industry standards or regulations that specify the use of load arrestors in galvanizing plants. Compliance with these standards is important for ensuring the highest level of safety.

Before installing load arrestors, it's advisable to consult with safety experts, equipment manufacturers, and industry guidelines to determine the most suitable type of load arresters for your plant's needs and to ensure proper integration into your safety protocols. Be sure to contact Guard Load Arrest if you require advice about your particular setup.

Protecting Equipment that is Suspended at Height

If you're looking for information about how to protect equipment that is suspended at height, you're in the right place!

Protecting equipment that is suspended at height is an important aspect of workplace safety, especially in industries such as construction, maintenance, and industrial operations where workers often interact with elevated equipment. Proper equipment protection helps prevent damage, accidents, and potential injuries. Here are some key considerations and strategies for protecting suspended equipment:

  • Anchorage and Rigging Points: Ensure that the anchorage points, rigging, and support structures used to suspend the equipment are robust, well-maintained, and properly rated for the intended load. Regular inspections and load calculations are essential to ensure the stability and safety of the equipment.
  • Fall Protection: If workers need to access or work around suspended equipment, they should be equipped with appropriate fall protection gear. This includes harnesses, lanyards, and self-retracting lifelines. Fall arrest systems help prevent workers from falling in case of a slip or mishap.
  • Load Arrest: If there is any risk that suspended equipment would fall, installing a load arrest device(s) should be considered. Specifically designed to be used in collaboration with primary lifting devices, such as hoists, load arrestors provide a crucial secondary safety back-up for overhead loads. Should the primary device or support fail, Guard load arrestors automatically stop the load from falling, thereby preventing damage to the load and, most importantly, protecting people or assets below.
  • Protective Covers: Depending on the nature of the equipment, consider using protective covers or enclosures to shield it from environmental elements like rain, dust, and UV radiation. This helps prolong the life of the equipment and maintain its functionality.
  • Anti-Swing Measures: Suspended equipment can sway or swing due to wind or movement, which can pose risks to both equipment and workers. Implement anti-swing devices or techniques to minimize swinging and ensure stability. This might include using dampening systems or controlling movement through tag lines.
  • Lockout/Tagout: If the suspended equipment is part of a system that requires maintenance or repair, follow proper lockout/tagout procedures. Lockout/tagout involves isolating and securing energy sources to prevent accidental startup while maintenance is being performed.
  • Regular Inspection and Maintenance: Establish a routine inspection and maintenance schedule for both the suspended equipment and the rigging systems. Any signs of wear, corrosion, or damage should be promptly addressed. Proper maintenance helps prevent unexpected failures and ensures safe operation.
  • Training: Workers who interact with suspended equipment should receive proper training on its safe use, as well as emergency procedures in case of accidents or malfunctions. Training promotes awareness and helps workers respond effectively to potential hazards.
  • Emergency Preparedness: Have clear emergency protocols in place in case of equipment failure, accidents, or unexpected incidents. Workers should know how to respond to emergencies and how to evacuate the area safely.
  • Documentation: Maintain detailed records of inspections, maintenance activities, and any modifications made to the suspended equipment or rigging systems. Documentation helps track the equipment's history and ensures that it's kept in safe working condition.
  • Compliance with Regulations: Ensure that all safety measures are in compliance with relevant industry standards and regulations. Adhering to safety guidelines helps minimize risks and potential liabilities.

Remember that protecting suspended equipment is a comprehensive effort that involves multiple factors. Prioritize safety, regular maintenance, and adherence to best practices to create a secure working environment for both equipment and workers.

Case Study: NinjaCross

Client: NinjaCross Systems, aqua fitness

Distributor: Load Halt Inc., USA

Problem:

Our distributor Load Halt was approached by NinjaCross, the market leader in North America for aqua fitness systems, to provide a safe system of work for their structures that are suspended above pools.

The concern was that, in the event of a failure of any part of the hoisting system, the structure had the potential to fall onto users or whilst users were using the equipment. This could potentially trap users under the water.

Solution:

The building structure above the Ninjacross system was used as an anchor point for a Guard Load Arrestor, providing a failsafe in case the primary system failed.

A Guard Load Arrest device is a simple and cost-effective solution that allows freedom of movement for the Ninjacross equipment. The Guard's cable extends and retracts, following the movement of the load. The device's deployment also provides a safe system of work for a structure that is suspended above people.

These units were fitted with stainless steel cables and shackles to prevent corrosion in the various locations that they are going to be used.

Case Study: St George’s Hall

ClientSt George’s Hall, Bradford Theatres

Problem:

The concert hall’s engineering team reached the conclusion that, to provide a safe system of work, adding-in Guard Load Arrest protection to the system would be the correct solution. However, with St George’s Hall being an old concert hall, the pipe we had to pass the load arrestor’s cable through was extremely narrow and, when researching the project, no obvious answer became apparent to allow the cable, ferrule, thimble & shackle to pass through the pipe from the anchorage point to the truss below within the theatre.

Solution:

Guard Load Arrest deployed at St George's Hall, Bradford UK

The new configuration of the bottom shackles on Guard Load Arrestors means that the shackle can be easily removed from the cable (the pin fits through the thimble), thereby solving part of the problem.

Due to the pipe being so narrow, the standard thimble still wouldn’t pass through the pipe. However, with Guard Load Arrest being the product manufacturer (with a full understanding of the product’s technical file), we were able to change the thimble to a narrow gauge alternative. This allowed the thimble to fit through the narrow pipe and then the shackle be reattached through the thimble.

This solution was achieved by Guard Load Arrest being able to manufacture the solution in accordance with the technical file and provide a solution that worked precisely for the customer.

Our range of Guard Load Arrest devices help to ensure our customers comply with any applicable local legislation pertaining to lifting equipment. In this article we explore how Guard Load Arrestors are employed by our UK customers to achieve compliance with UK legislation for lifting equipment.

1500 Guard Load Arrestor with multiple hoists

The Lifting Operations and Lifting Equipment Regulations (LOLER) have been enforced in the UK since the 5th December 1998. Regulation 6 (b) (ii) within this legislation states that;

Every employer shall ensure that lifting equipment is positioned or installed in such a way as to reduce to as low as is reasonably practicable the risk from a load falling freely.

As with most legislation, this seemingly simple statement is open to interpretation, so in 2014 the Health and Safety Executive (HSE) published an Approved Code of Practice (ACOP) to clarify and set out what companies should do to meet their obligations under LOLER. The ACOP elaborates on Regulation 6 (b) (ii) by stating;

"Various methods can be used to minimise the risk of the load falling out of control. These include:

(a) multiple ropes/chains;

(b) lifting mechanisms with a high factor of safety or strength;

(c) safety gear;

(d) check valves (for hydraulic systems); and

(e) safety nets for palletised loads.”

Installing a Guard Load Arrestor alongside your primary lifting equipment can mitigate the risk of the load falling out of control by providing an independent safety function with complete redundancy to ensure compliance with LOLER.

Regulation 8 of LOLER covers the Organisation of lifting operations and Regulation 8 (1) (c) states that;

Every employer shall ensure that every lifting operation involving lifting equipment is carried out in a safe manner.

The ACOP elaborates on this by considering this regulation in relation to working under suspended loads;

Where practicable, loads should not be carried or suspended over areas occupied by people.

Where this is not practicable you should establish a safe system of work which minimises the risks to people who may need to be below the load.

Where it is necessary to leave loads suspended you should ensure that access to the danger zone is prevented and that the load has been secured properly.”

A Guard Load Arrestor running in conjunction with your primary lifting equipment can help you to establish a safe system of work which minimises the risks to people who may need to be below the load.

BS 7906-1:2005

This standard covers the use of lifting equipment for performance, broadcast and similar applications.

Part 1: Code of practice for installation, use and removal of above stage equipment (excluding trusses and towers)

“Chain hoist categorizations must be considered when selecting electric chain hoists for the listing or suspending of loads over people, and under certain circumstances it is essential to implement an inertia reel load arrestor as a secondary suspension. The load arrestor provides an ideal, independent, fully redundant, secondary suspension in these scenarios.”

BS 7906-1:2005 provides recommendation for the safe use of lifting used to lift and traverse equipment and personnel for the following applications:

  • film;
  • television;
  • theatre and similar entertainment events;
  • conference and exhibition.

The recommendations cover the supply, installation, use, maintenance and removal of components and systems, documentation, periodic inspection, and thorough examination.

Section 8.19 of this standard details all considerations for the selection, maintenance, installation, and operation of chain hoists within the entertainment industry. Chain hoists used in the entertainment industry fall into two categories: Category A and Category B.

Category A hoists are declared by the manufacturer as intended for use by the entertainment industry for lifting and suspending loads over people and meeting the requirements of BS 7905-1 or DIN 56925.

Category B hoists are not intended by the manufacturer for lifting or suspending loads over people.

Chain hoist categorizations must be considered when selecting electric chain hoists for the listing or suspending of loads over people, and under certain circumstances it is essential to implement an inertia reel load arrestor as a secondary suspension. The Guard Load Arrest products provide an ideal, independent, fully redundant secondary suspension in these scenarios.

The table below provides additional guidance on the selection of electric chain hoists.

Guard Load Arrest Startet

Guard Load Arrest ist gerade auf den Markt gekommen und bietet dauerhafte Lösungen zur Ladungssicherung entertainment und industriell Sektoren.

Das Produktsortiment bietet Schutz von 150 kg bis 1500 kg, und Entwicklungen sind bereits im Gange, um das Sortiment noch weiter zu erweitern.

Eine der häufigsten Anwendungen von Lastableitern ist als Sekundärsicherung für Kettenzüge. Patrick Evans, Geschäftsführer, erklärt mehr:

EN 17206 schreibt vor, dass bei der Installation von Elektrokettenzügen zwei unabhängige Sicherheitslösungen erforderlich sind. Ob die Sekundärbremse eines Hebezeugs das erforderliche Maß an Sicherheit bietet, hängt von Ihrer Risikobewertung ab, aber wir stellen immer mehr fest, dass Installateure Guard-Einheiten neben Hebezeugen einsetzen, um einen separaten Schutz zu bieten, falls das Primärsystem ausfallen sollte.“

Natürlich verfügen Elektrokettenzüge in der Regel über eine Sicherheitsbremse, die eingreift, wenn die Primärbremse ausfällt. Aber was ist die Reserve, wenn die Kette oder der Anker des Hebezeugs versagen? Patrick sagt weiter:

„Es stehen einige Optionen zur Verfügung, eine davon besteht darin, einfach ein festes Stahlseil als sekundäre Sicherheitslösung anzubringen. Das wäre extrem sicher. Allerdings verzichten Benutzer zunehmend auf diese Methode aufgrund der hohen Kosten für das Versenden eines Riggers zum Abnehmen und Neufixieren jedes Mal, wenn er benötigt wird. Schutzlastsicherungen sind eine alternative kostengünstige Option, die dieses Problem überwindet, indem sie ein Stahlseil bereitstellen, das sich automatisch aus- und einzieht, wenn es der Bewegung der Last folgt, ohne dass es gelöst werden muss.“

Wenn die primäre lasttragende Ausrüstung ausfällt, stoppt die Guard-Lastsicherung automatisch das Herunterfallen der Last, wodurch Schäden an der Ausrüstung verhindert und, was noch wichtiger ist, das Publikum/die Darsteller darunter geschützt werden.

 

Nicht nur im Unterhaltungsbereich werden zunehmend Guards installiert. Viele industrielle Anwendungen profitieren von der Lastarretierung. Patrick führt aus:

„Es gibt eine Vielzahl von Anwendungen, bei denen Lastableiter eine ideale Sicherheitslösung darstellen. Heben oder hängen Sie Geräte oder Materialien, die nicht fallen dürfen? Wenn dies der Fall ist, sollten Sie die Installation einer Guard-Lastsicherung als Schutz für den Fall in Betracht ziehen, dass die primäre Hebeausrüstung ausfällt.“

„Produktionslinien können sich keine langen Stillstandszeiten leisten, um heruntergefallene Geräte zu reparieren. Ein gutes Beispiel ist, wie einige Automobilhersteller sich auf Guard-Lastsicherungen verlassen, um wichtige Punkte in der Produktionslinie zu schützen; Ihre Ingenieure identifizierten ein Risiko, dass schweres Gerät während des Gebrauchs abschaltet, was zu einem unkontrollierten Sturz auf den Werkstattboden führen könnte. Hier kommt Guard Load Arrest ins Spiel. Ein an der richtigen Stelle positionierter Guard-Lastschutz fängt herunterfallende Geräte automatisch auf und verhindert, dass sie auf den Boden aufschlagen. Unsere Produkte sind so vielseitig und zuverlässig, dass sie sogar als Sicherheitsvorrichtung für das Heben radioaktiver Materialien in einem bestimmten britischen Kernkraftwerk eingesetzt werden!“
