High mast winches provide controlled raising and lowering of luminaire carriages for inspection and maintenance.
SWIN Industries manufactures manual and electric high mast winches for raising and lowering luminaire carriages in high mast lighting systems.
The winch arrangement can be customised according to the mast height, carriage weight, wire-rope system, operating method, speed, drum configuration and customer specification.
Manual systems are suitable where controlled hand operation is required and the mast arrangement is designed for the selected winch and rope system.
Electric high mast winches reduce manual effort and can be supplied with project-specific motor, gearbox, brake and controls.
Drum diameter, groove arrangement and rope capacity can be developed according to the number of ropes and required travel.
Forward-reverse operation, pendant control, protection devices and limit-switch provisions can be considered based on the approved system design.
The winch is one part of the complete high mast system. The mast, carriage, rope path, pulleys, locking arrangement, structural design and maintenance procedure must be evaluated together.
For replacement or retrofit requirements, photographs, measurements and details of the existing winch and rope system should be provided before finalising the proposal.
The complete high mast lifting and locking system must be inspected and maintained according to the approved design and operating procedure. Do not rely on the winch brake alone where a separate carriage-locking system is required.
