RIGGING AND REEVING
At the job site, rig from the top down. Lower wire rope until you have about 10 feet of rope on the ground
(hoist is not yet reeved). Complete the tie point with 3 fist grips (or J-clamps), thimble and shackle (torque
fist grips to manufacturer’s recommendations). Store the extra wire rope in a coil on the roof.
HOIST & SKY LOCK INSTALLATION & TESTING
Suspended Platform Assembly
Follow manufacturer’s instructions.
If used, install an electric yoke on the platform (wrapped around center guardrails) to provide power to
each hoist.
Secure source power line(s) to Suspended Platform by strain relief(s) or other load-bearing device.
Plug the power line into yoke (if used).
Allow sufficient power line length to permit free platform travel without undue strain to the power line
and platform.
Sky Lock Installation
Insert the end of hanging wire rope through Sky Lock.
Move Sky Lock up rope to a location above hoist attachment point.
Test Sky Lock.
Support Sky Lock vertically. Drop Sky Lock down the wire rope.
Brake should lock onto rope within 3 inches or less.
Slide Sky Lock up wire rope 1 inch.
Turn Reset Handle clockwise to reset Sky Lock.
Repeat procedure twice. Leave Sky Lock on line for hoist reeving.
Sky Lock must lock onto rope within 3 inches or less. If it does not, Sky Lock must be
replaced.
After test, proceed with hoist installation.
Hoist Installation
Place hoist next to Suspended Platform Stirrup.
Connect Power.
On dual voltage hoists (110 or 220), set voltage selector switch to source voltage BEFORE
connecting power. Then connect power.
Thread wire rope through hoist.
Keep hands clear of pinch point where wire rope enters hoist.
Feed brazed and pointed end of wire rope with Sky Lock Brake already hanging on the rope
into hoist entrance guide until rope stops.
To start self-reeving, move Directional Switch to UP direction.
Wire rope must be free to travel without interference.
NOTE: Adjust wire rope length as you change elevations. Reeve the hoist, form a 360° loop in the
tail end and retain with a fist
ri
. Before dereevin
the hoist
remove the fist
ri
.
