SINGLE DRUM WINCH SYSTEM
In the single drum winch system, a winch cable is attached to two suspension ropes which raise and lower the lantern carriage. 6mm stainless steel wire ropes are used to suspend and hold the carriage in place.

For heavier loads, a double drum winch is required

DOUBLE DRUM WINCH SYSTEM
Although the gearbox and drum are separate entities they are driven by a single input shaft that can drive both drums or just one drum by using the adjusting handle supplied.

POWER OPERATION
Both single drum and double drum systems are easily operated using a power tool. A manual winding handle can be used for backup or for final adjustments.

Safety is ensured as the winch gearbox has a 50:1 ratio, which in itself provides protection against the winch winding under pressure. As an extra precaution, the winch has a gravity catch which also prevents involuntary winding when the winch is stationary making it impossible for the winch to unwind in error.

As a further precaution, the power tool provided is operated from minimum 5M away from the base of the mast using a wired remote control station.
