TROUBLE SHOOTING (Continued)

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Motor brake noise or chatter (while starting hoist)

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

1.

Brake needs adjustment

 

 

 

 

1. See BRAKE ADJUSTMENT, page 9.

 

 

 

 

 

2.

Low voltage

 

 

 

 

2. Check voltage at the hoist reversing contactor while the hoist is lifting a load. Voltage should be no less than 90% of

 

 

 

 

 

 

 

 

 

the voltage specified. 115 volt hoists are particularly subject to voltage drop problems due to their high current draw.

 

 

 

 

 

 

 

 

 

Conversion to 230 volt operation is suggested in extreme cases.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Motor brake “buzz” (anytime hoist is running)

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

1.

Brake needs adjustment

 

 

 

 

1. See BRAKE ADJUSTMENT, page 9.

 

 

 

 

 

2. Broken shading coil on brake frame

 

 

2. Replace shading coil or complete brake frame assembly.

FREQUENCY OF INSPECTION

 

 

 

 

 

 

 

 

 

 

 

 

 

Frequent — Indicates items requiring inspection daily to monthly. Daily inspections may be performed by the operator if properly

designated.

 

 

Periodic — Indicates items requiring inspection monthly to yearly. Inspections to be performed by or under the direction of a pr operly designated period. The exact period of inspection will depend on frequency and type of usage. Determination of this period will be based on the user’s experience. It is recommended that the user begin with a monthly inspection and extend the periods to quarterly, semi-annually or annually based on user’s monthly experience.

Figure 10A — Recommended Inspection and Maintenance Check List

NOTE: This inspection and maintenance check list is in accordance with our interpretation of the requirements of the Safety Standard for Overhead Hoists ASME B30.16. It is, however, the ultimate responsibility of the employer/user to interpret and adhere to the applicable requirements of this safety standard.
