ALTERNATE PROCEDURE B
1. Place ladder perpendicular to building with bottom shoes resting against building to prevent slipping.
2. Use a man on the roof with rope dropped from the roof and attached to the top bracket to pull up the
ladder.
3. When track reaches a vertical position, carefully turn the ladder 180° with platform away from building.
Allowance must be made for an overhang of building.
AFTER USING ONE OF THE PROCEDURES (A OR B) CONTINUE AS FOLLOWS:
4. Securely tie ladder to the roof with a rope fastened to a cross tie or top bracket to prevent ladder from
slipping. Platform will not roll on track if rope is fastened around the rails
5. Mount the power unit on the 3
handles on the power hoist. When facing the power unit from the rear or building side of the ladder, the
power unit handles are on your right.
6. Using a rope from the roof and with brake released, pull the hoist cable to the roof on the underside of
ladder and reeve through the sheave on the top bracket. Drop the cable to ground (on platform side of
the ladder) and fasten to shackle provided on the platform.
NOTE: The LH 400 requires a double line. After dropping cable end to ground, reeve cable through the
sheave on LH 400 platform and pull end once more to the roof on platform side of ladder. Fasten end to
shackle provided on top bracket.
7. Remove the tie rope holding platform in position on the ladder.
8. Make certain that both ladder shoes or spikes are firmly resting on a level surface. This prevents ladder
slippage or uneven loading of ladder which could cause damage or injury to equipment or personnel.

operating instructions. Your platform hoist is now ready for use.
