OPERATION
The four most important aspects of hoist operation are:
1.Follow all safety instructions when operating the hoist.
2.Allow only people trained in safety and operation of this product to operate the hoist.
3.Subject each hoist to a regular inspection and maintenance program .
4.Be aware of the hoist capacity and weight of load at all times.
Operators must be physically competent. Operators must have no health condition which might affect their ability to act, and they must have good hearing, vision and depth perception. The hoist operator must be carefully instructed in his or her duties and must understand the operation of the hoist, including a study of the manufacturer's literature. The operator must thoroughly understand proper methods of hitching loads and should have a good attitude regarding safety. It is the operator's responsibility to refuse to operate the hoist under unsafe conditions.
Initial Operating Checks
Hoists are tested for proper operation prior to leaving the factory. Before the hoist is placed in service the following initial operating checks should be performed.
1.After installation of trolley mounted hoists, check to ensure the hoist is centered below the trolley.
2.Check for air leaks in the supply hose and fittings to pendant, as well as from pendant to manifold.
3.When first running the hoist or trolley motors, some light oil should be injected into the inlet connection to allow good lubrication.
4.When first operating the hoist and trolley it is recommended that the motors be driven slowly in both directions for a few minutes.
5.Operate the trolley along the entire length of the beam.
6.Inspect hoist and trolley performance when raising, moving and lowering test loads. Hoist and trolley must operate smoothly and at rated specifications prior to being placed in service.
7.Check that trolley and hook movement is in the same direction as arrows and pendant control labels.
8.Raise and lower a light load to check operation of the hoist brake.
9.Check hoist operation by raising and lowering a load equal to the rated capacity of the hoist a few inches (cm) off the floor.
10.Check operation of limit devices.
11.Check to see that the hoist is directly over the load. Do not lift the load at an angle ("side pull" or "yard").
12.Check to see the hoist is securely connected to the overhead crane, monorail, trolley or supporting member.
13.Check to see that the load is securely inserted in the hook, and that the hook latch is engaged.
WARNING
•Allow only personnel trained in safety and operation of this product to operate hoist and trolley.
•The hoist is not designed and not suitable for lifting, lowering or moving people. Never lift loads over people.
WARNING
•The hook latch is intended to retain loose slings or devices under slack conditions. Hook latches are not intended to be
Pendant
The pendant is a remote control that allows the operator to control the positioning of a load. It will allow the operator to control hoist movements from a distance, thereby allowing exact positioning of a hook.. The four lever pendant controls both hook and trolley positions.
Emergency Stop
The Emergency Stop button, when activated, will immediately stop all operations of the hoist and trolley. The Emergency Stop button will remain depressed after activation.
To reset four lever pendants Emergency Stop button twist (rotate) Emergency Stop button clockwise until button releases and spring returns to its original position. Depress "ON" button.
