Use electric hoist the note

Use electric hoist the note
Electric hoist is good, but when use some noteworthy aspects:
1. When lifting can not sew, tilt manual hoist heavy objects you for your cooperation.
2. When the hoist lifting, it is important to ensure that at least 3 ring steel wire rope, rope cylinder force is too large to prevent the wire rope fell off the rope drum.
3. Regularly check whether the installation of the elevator.
4. Please don't use don't overload the hoist equipment weight lifting objects when using the elevator.
5. The operating personnel please don't in the case of alcohol, medication and illness elevator operation.
6. It is forbidden to anyone standing when hoist lifting heavy objects in lifting the weight of below.
7. To manipulate when the steel wire rope, please wear with thick gloves, please don't let slip from your hand, and wire rope lest cause slippery hurt or injured.
8. The elevator to carry people in any form, or as the elevator promotion tools.
9. Please do not arbitrarily or welding of elevator parts.
10. The micro electric hoist elevator installation position must choose in consistent with the need, and easy operation.

Electric hoist is mainly divided into wire rope electric hoist and chain electric hoist two kinds big

Electric hoist crane when a car and improper operation method, electric hoist can make crane swing accident. Electric hoist crane hoisting, should stop when wire rope or chain taut, electric hoist by direction again for hook, hook shaking while lifting workers chainb lock check whether "hang up; Don't too hard, when the electric hoist lifting when lifting objects from disorder may speed up the lifting; Electric hoist lifting crane content not too high, generally more than safe passage highest 0.5 m as well. Electric hoist crane runtime. Under the conditions allow, the manual hoist hanging from the ground 0.5 m or so, the rigger balance objects from behind electric hoist crane, and under the rigger command to bypass obstacles.
Don't intermittent electric hoist run time, in the long run, the best to run either for a long time as well. Electric hoist at runtime should guarantee the smooth ", if electric hoist crane swing or jitter, should be in the run run while stabilizing hook, not allow it to shake or place. Electric hoist fault occurs is normal, the service life of equipment has its specific problems we think of a solution. Sometimes, the hoist motor voltage is normal, but the gourd is not working, it should be considered for other reasons, such as: motor burned, need to change the motor maintenance. Chain electric hoist long-term need not, poor maintenance of brake wheel and the end cover rust, brake wheel does not open, when starting motor only "hum" sound, turn up, block doesn't work. At this time, should remove brake wheel, cleaning rust on the surface, and test again; Serious motor chamber, also can make the motor does not rotate, found that this kind of situation, should stop to use, must be for repair or replacement motor, to guarantee the normal work of the gourd. In addition, it is forbidden to use electric hoist overload in production, when the goods excessive overload, explosion-proof electric hoist crane didn't move the goods, the motor only thrum "hum", instead of running, serious when burning motor, or even cause an accident, should immediately stop at this moment, to reduce the goods, make the gourd work under rated power.
