• Backup systems that can engage if the primary system fails
• Emergency stop buttons that can be activated by workers in the event of an emergency
• Fail-safe mechanisms that prevent the device from failing if a single component fails

Material Selection

The materials used in the construction of an anti-fall device are also critical. The device must be able to withstand the forces generated during a fall and remain functional. Some materials that are commonly used in anti-fall devices include:

• High-strength steel
• Aluminum alloys
• High-density plastics

The selection of materials must also take into account factors such as weight, durability, and cost.

Mechanical Components

The mechanical components of an anti-fall device are the parts that actually engage to prevent a fall. These components must be designed to withstand repeated use and be able to engage quickly and reliably in the event of a fall. Some mechanical components that are commonly used in anti-fall devices include:

• Braking systems, such as permanent magnet eddy current braking (PM-ECB) technology
• Tensioning systems that keep the device taut and prevent slack
• Shock absorbers that can absorb the force of a fall and prevent injury to the worker

By considering these design principles, it is possible to create an anti-fall device that is both effective and reliable.

Installation and Usage

Mounting Procedures

When installing an anti-falling device for a construction hoist, follow the manufacturer’s instructions carefully. The device should be mounted securely to the hoist and the supporting structure.
