Page 3: Safety Recommendatioins
1.0 SAFETY RECOMMENDATIONS Safety for operators and ground personnel is of prime concern. Always take the necessary precautions to ensure safety to others as well as yourself. To ensure safety, the prime mover and hoist must be operated with care and concern by the operator for the equipment and a thorough knowledge of the machine’s performance capabilities. - Page 4 five (5) wraps of wire rope on the drum. 16. Never attempt to clean, oil or perform any maintenance on a machine with the engine or prime mover running, unless instructed to do so in this manual. 17. Never operate hoist controls unless you are properly positioned at the operator’s station, and you are sure personnel are clear of the work area.
- Page 5 33. Avoid shock loads. This type of load imposes a strain on the hoist many times the actual weight of the load and can cause failure of the cable or of the hoist. 34. Hoist operators must be trained in the proper, safe operation of the hoist. WWH-IW-010_B Page 5 of 24...

Page 7: Hoist Installation
HOIST INSTALLATION 1. The hoist should be mounted with the centerline of the drum in a horizontal position. The mounting plane of the base may be rotated in any position around this centerline. 2. Because of the design of the mounting base, the direction of line pull should only be as shown in the above illustration. - Page 8 4. The vent plug must always be located above the horizontal centerline. If the hoist is mounted on a pivoting surface, be sure vent plug remains above the centerline in all positions. If necessary, reposition bearing support and vent plug as follows: A.
- Page 9 WARNING! DO NOT use a control valve with any detents or latching mechanism that would hold the control valve in an actuated or running position when the operator releases the control handle. Use of the wrong type of control valve could lead to unintentional operation of the hoist, which could result in property damage, personal injury, or death.
- Page 10 Under continuous operating conditions the temperature of the oil at any point in the system must not exceed 180°F (82°C). Optimum oil temperature is generally considered to be 120-140°F (49-60°C). In general terms; for continuous operation at ambient temperatures between 50 and 110°F (10 to 43°C) use ISO 46;...

Page 13: Hoist Operation
HOIST OPERATION The hydraulic motor drives the sun gear of the primary planetary gear set through the splined inner race of the overrunning brake clutch. When driven by the sun gear, the primary planet gears walk around the ring gear in the drum and drive the primary planet carrier. -
Page 14: Emergency Lowering Procedures For Hoists With Gear Motors
EMERGENCY LOWERING PROCEDURES FOR HOISTS WITH GEAR MOTORS The following procedure releases the multiple disc brake while leaving the brake valve closed. Since gear type motors are not zero leakage devices, internal motor leakage permits the load to slowly rotate the motor although its outlet is blocked by the closed brake valve. - Page 15 motor port or manifold. The standpipe is installed with the long, open end pointing up in a vertical position to reservoir. While the load is being lowered, hydraulic oil MUST be added to the standpipe as necessary to prevent to the motor from running dry.

Page 16: The Brakes Contrast Test
7.0 THE BRAKES CONTRAST TEST ALL WPT planetary hoists have a spring applied, hydraulically released, multiple disc brake inside the hoist housing. This brake holds a suspended load when the directional control valve is in neutral, or when the directional control valve is in neutral, or when hydraulic power is lost. -

8.0 MAINTENANCE Adhering to the following maintenance schedule will keep your hoist in top condition and performing as it should with a minimum of repair. 【MONTHLY】 1. Check the oil level and maintain it to the oil level to round hex head socket plug. 2. -
Page 18: Troubleshooting
9.0 TROUBLESHOOTING ！ WARNING If a hoist ever exhibits any sign of erratic operation, or load control difficulties (i.e. load creeping or chattering) appropriate troubleshooting tests and repairs should be performed immediately. Continued operation in this manner may result in property damage, serious personal injury or death. - Page 19 Oil analysis may indicate contamination has worn motor shaft and seal. Thoroughly flush entire hydraulic system and install new filters and oil. Install new motor seal. Replace the motor. 1. Excessive system back pressure acting on the brake release port. Increase the hydraulic system pressure.
