LIST OF SAFETY GADGETS / SYSTEMS

RSP SAFETY GADGETS

Safety Locks:

It is widely used in India for performing various applications at heights for jobs like external painting, wall plastering, installing.

Over Hoist / Top Limit Switch:

Function of over hoist limit switch is to prevent the over run of the cradle and hitting the suspension mechanism.When the limit switch level touches upper end, power supply to electrical motor gets stopped.

Centrifugal Speed Limiter:

If RSP travelling (Up or Down) speed increased beyond the rated speed, this devices gets activated and stops RSP operation. This device generally activates during free fall and brake failure conditions.

Anti-Tilting Cut off:

This is a protection system to ensure uniform loading across the platform. If the load is concentrated on one side, the platform will get tilted resulting in unsafe condition.This device gets actuated once the platform angle is tilted more than 4 Degrees and cuts off the power supply.

Electromagnetic Brake with manual release:

Hoist motor is provided with electromagnetic brake as primary holding device. Manual release mechanism shall help the cradle to be lowered to the ground level in case of power failure.

Anti-Sway Restriction:

This mechanism avoids the swaying of RSP in the horizontal plane. A separate wire rope (Laid from building top to ground) will pass through the sway arrestor roller fitted on the platform. This will thrust the platform to remain in the horizontal plane without swaying action.

Overload Cut-off using Digital Load Cell:

Function of over load limit switch is to prevent the over loading of the cradle by alarming the operator. The load will be measured by electronic load cell fitted on the platform.A manual or digital display of the load is also compulsory.

Locking arrangement for upper counter weights:

All the counter weights must be firmly placed on level ground and locked with lock & key arrangement to avoid un-authorized removal of counter weights.

Over current protection thro' Relay (OLR):

This will be part of electrical control system.If the electrical motor draws beyond rated current due to overloading, this protection device will cut-off the electrical system.

Panel board Lock & key:

RSP Electrical panel must be locked with lock & key arrangements to avoid unauthorised operation.

Over Head Protection:

It protects workers from falling building material like sand, dust, water, etc while working on site.It also protects them from sun light or rain water.

Galvanised Wire rope with proper U Clamps:

Galvanised Wire rope with proper “U” clamps to be used.
