Electric Chain Hoist Operator’s Manual/EN/11.30.10 4 4.1 ELECTRIC CHAIN HOIST CONSTRUCTION General Hoist Construction Overhead hoists are defined in the ANSI / ASME standards as a machinery unit that is used for vertical lifting service involving material handling of freely suspended (unguided) loads. Overhead hoists are a basic and versatile piece of equipment used in manufacturing, warehousing, construction, and numerous other applications to aid workers in the handling and moving of loads.
Electric Chain Hoist Operator’s Manual/EN/11.30.10 Electric Power The hoisting motion (lifting or lowering) of an electric powered hoist is initiated when the operator grasps and activates a control device. The control device has push buttons that energize, through a series of contractors and other electrical components, an electric motor. The electric motor transmits power through the hoist gearing to the hoist load chain sprocket; thereby, lifting or lowering the hoist load hook.
Electric Chain Hoist Operator’s Manual/EN/11.30.10 Trolley Mounted Trolley mounted hoists are hook mounted or lug mounted hoists suspended from a trolley; or a hoist having an integral trolley as part of the hoist frame, that allows travel motion on the lower flange of a monorail beam, or the lower flange of the bridge beam of an overhead crane.
Electric Chain Hoist Operator’s Manual/EN/11.30.10 4.5 Directional Travel of Overhead Hoists Hoist motion is the vertical travel motion direction of the hoist load hook. The hoist operator should be familiar with the hoist (or crane) controls and understand what type of motion will occur when any one of the control devices is activated. The controls SHALL be marked, and all markings SHALL be legible.
Electric Chain Hoist Operator’s Manual/EN/11.30.10 All motions of multi-speed powered hoists should be started in the slowest speed available for that motion, and then the speed should be increased until the desired speed is obtained. At the beginning of hoisting motion, the load should be lifted only a few inches and stopped to check the holding brake before continuing with the lift. The hoist should be brought directly over the load before rigging the load to the hoist load hook.
Electric Chain Hoist Operator’s Manual/EN/11.30.10 4.6 Principal Parts of an Electric Chain Hoist Hoist operators should be familiar with the parts of a hoist and have a thorough knowledge of hoist control device functions. Figure 1.

Electric Chain Hoist Operator’s Manual/EN/11.30.10 5 SAFE OPERATING PRACTICES The operation of an electric chain hoist can be categorized by the various sequential parts of a particular cycle of use. The typical sub-sections are: BEFORE EACH SHIFT or THE FIRST TIME THE HOIST IS USED EACH SHIFT BEFORE OPERATING A HOIST AND APPLYING A LOAD MOVING THE LOAD PARKING THE LOAD Taking precedence over any specific rule, however, is the most important rule of all: “USE COMMON SENSE.
Electric Chain Hoist Operator’s Manual/EN/11.30.10 Daily inspection items that should be performed by the operator at the start of each shift, or at the time the hoist is first used during the shift, include the below items: ITEM INSPECTION CHECK POINTS Tagged Hoist Check that hoist is not tagged with an out-of-order sign. Control Devices Check that all travel motions agree with control device markings. When checking hoist travel motion, always use “UP” control first.
Electric Chain Hoist Operator’s Manual/EN/11.30.10 • SHALL visually inspect hook latches for proper operation or damage that does not allow roper operation. • SHALL test operation of the primary upper limit device of the hoisting motion. • SHALL report to supervisor if warning label or labels are missing or illegible. • SHALL report to supervisor any damage or malfunctions. • SHALL NOT operate hoist if any damage or malfunctions exist.
Electric Chain Hoist Operator’s Manual/EN/11.30.10 5.2 Before Operating A Hoist and Applying a Load Bring the hoist directly over the load. Lower the load hook so it can be attached directly to the load, the slings, or any other device used to rig the load. The load, sling(s), or other lifting device should be fully seated in the saddle or bowl of the hook. Verify that the hook latch is operational and closes the throat opening of the hook.
Electric Chain Hoist Operator’s Manual/EN/11.30.10 SHALL report to the supervisor any damage or malfunctions. SHALL NOT operate hoist if it is tagged with an out-of-order sign. SHALL center hoist over load. SHALL NOT operate a hook mounted hoist when the hoist is restricted from forming a straight line from top hook to load hook in the direction of loading. SHALL NOT use the load chain as a sling to wrap around the load.
Electric Chain Hoist Operator’s Manual/EN/11.30.10 5.3 m Moving the Load WARNING: DO NOT LIFT PERSONNEL. DO NOT LIFT LOADS OVER PEOPLE. NOTE: Hoists are intended only for vertical lifting service of freely suspended, unguided loads. Do not use a hoist to lift loads that are not lifted vertically, loads that are not freely suspended, or loads that are guided. If such conditions exist, the operator should contact the supervisor for instructions.
Electric Chain Hoist Operator’s Manual/EN/11.30.10 SHALL avoid unnecessary inching and quick reversals of direction. SHALL only lift the load a few inches to verify that the load is properly balanced before continuing with the lift. SHALL only lift the load a few inches to verify that the hoist braking system is functioning properly before continuing with the lift. SHALL avoid swinging of the load or hoist load hook when the trolley (if applicable) or hoist is traveling.
Electric Chain Hoist Operator’s Manual/EN/11.30.10 5.5 Hoist Limit Devices Powered hoists must be equipped with an upper limit device that will prevent the hoist load block from exceeding the upper limit of travel. Depending on the shape or size of the load being lifted, it may be impossible for some part of the load to come into contact with some part of the hoist, trolley, crane, or building structure before the load block reaches the upper limit of travel.
Electric Chain Hoist Operator’s Manual/EN/11.30.10 5.7 Recommended General Do Not’s It is Recommended that the Operator: DO NOT operate a hoist that is damaged or has any actual or suspected mechanical or electrical malfunction. DO NOT attempt to lengthen load chain or repair damaged load chain. • DO NOT DO NOT allow a welding electrode to be touched to the load chain or load hook. DO NOT remove or obscure any instructions, warnings or warning labels on the hoist.
Electric Chain Hoist Operator’s Manual/EN/11.30.10 5.8 Operator Hand Signals Hoist operators are normally involved in rigging the load, attaching the load to the hoist load hook, and other tasks related to the load for which they have skills in addition to those required for operation of the hoist. Therefore, in addition to the specific information required to operate the hoist, hoist operators should be familiar with rigging procedures and practices.
Electric Chain Hoist Operator’s Manual/EN/11.30.10 6 APPENDIX – A – DEFINITIONS OF ELECTRIC CHAIN HOIST TERMS below-the-hook lifting devices – Devices that are not normally reeved onto the hoist chain, such as hook-on buckets, magnets, grabs, and other supplemental devices used for ease of handling certain types of loads. The weight of these devices is to be considered part of the load to be lifted.

Electric Chain Hoist Operator’s Manual/EN/11.30.10 m DISCLAIMER CAUTION: Improper operation of a hoist can create a potentially hazardous situation, which, if not avoided, could result in minor or moderate injury. To avoid such a potentially hazardous situation, the operator SHALL: 1. Maintain a firm footing or be otherwise secured when operating the hoist. 2. Check brake function by tensioning the hoist prior to each lift operation. 3. Use hook latches. Latches are to retain slings, chains, etc.
