    4.0 Operation Introduction  DO NOT WALK UNDER A SUSPENDED LOAD  HOIST OPERATORS SHALL BE REQUIRED TO READ THE OPERATION SECTION OF THIS MANUAL, THE WARNINGS CONTAINED IN THIS MANUAL, INSTRUCTION AND WARNING LABELS ON THE HOIST OR LIFTING SYSTEM, AND THE OPERATION SECTIONS OF ANSI/ASME B30.16 and ANSI/ASME B30.10. THE OPERATOR SHALL ALSO BE REQUIRED TO BE FAMILIAR WITH THE HOIST AND HOIST CONTROLS BEFORE BEING AUTHORIZED TO OPERATE THE HOIST OR LIFTING SYSTEM.

  • Page 22: Shall's And Shall Not's For Operation

    The operation of an overhead hoist involves more than activating the hoist’s controls. Per the ANSI/ASME B30 standards, the use of an overhead hoist is subject to certain hazards that cannot be mitigated by engineered features, but only by the exercise of intelligence, care, common sense, and experience in anticipating the effects and results of activating the hoist’s controls.

  • Page 23: Hoist Controls

     Improper operation of a hoist can create a potentially hazardous situation which, if not avoided, could result in minor or moderate injury, or property damage. To avoid such a potentially hazardous situation THE OPERATOR SHALL: • • Use the hoist manufacturer’s recommended parts Maintain a firm footing or be otherwise secured when operating the hoist.

  • Page 24: Adjusting The Controls

    4.3.3 Cord Control - When using a hoist with cord control, pull down on the appropriate colored cord to raise or lower the hoist. White indicates the raise control and red indicates lowering control. Release the cords to stop the hoist. Refer to Figure 4-2 below.

  • Page 25: Speed Adjustment Controls

    Speed Adjustment Controls 4.5.1 The hoist is equipped with speed adjustment controls. The controls allow the hoist lifting and lowering speeds to be reduced for those applications requiring slower speeds or better speed control. The speed adjustment controls are set for the highest speed from the factory. The speed adjustment controls are located on top of the valve section of the hoist as shown in Figure 4-4.

  • Page 26: Pendant Controllability Adjustment

    Pendant Controllability Adjustment 4.6.1 The standard pendant hose length is 8.1 feet. For longer pendant hose lengths the speed controllability from the pendant may be diminished. The reduction in speed control is a result of pressure loss due to the longer pendant hose. The pendant hose extension adjustment control provides a screw adjustment method to reduce the air pressure loss to provide normal pendant/hoist operation.
