Elevator installation and maintenance, the 2013 elevator installation manufacturers, elevator installation and maintenance advice. ① ⑤ ⑤ ⑤ zero ⑧ ⑨ ⑨ ⑤ ⑨ ⑨ Shandong Taian Lifting Machinery Co., Ltd. is manufacturing a variety of lifting equipment, professional production factory, mainly engaged in cranes, gantry cranes, bridge cranes, single girder cranes, double girder cranes, gantry crane, casting crane, metallurgical crane , crane accessories, crane maintenance, electric hoist, Shandong lifting appliances and other non-standard crane design, manufacture, sales and other business. While operating the elevator installation maintenance, chain, anchor and support the manufacture and sale. 1) wear around the lifting gear pulley block, wire rope pulley groove angle. In any case, the declination of the pulley groove must not exceed 4 ° ~ 6 °. Because, when the wire rope in the declination of the pulley groove is too large, the wear of the rope and pulley groove side intensified, on the other hand, the rope is easy to slide the rope groove, so that the lifting operation can not be normal, or even an accident. (2) wear a rope around the the lifting gear pulley or tackle must comply with the requirements of the pulley. When the rope diameter exceeds the requirements of the pulley would aggravate the wear of the sheave, also increased wear of the wire rope. Certain from the weight of the pulley should be equipped with the corresponding thickness of the wire rope. (3) block and tackle by wear around a trial hanging detailed examination of the various parts is good, the friction at each other the whether the Kasheng, friction or rope, if inappropriate, after adjustment formal lifting. (4) tackle the force of the direction of change is large, or in the high-altitude operations, not to declare hook tackle to prevent decoupling. Such as the use of hook block, you should take protective measures. Hang hook, with thin wire hook mouth shut so that the hook can not emerge; hook with Picasso plate, this hook is more convenient to use, hang hook, Picasso plate under the action of the spring bounce the hook mouth shut. (5) the blocks do not overload the pulley cracks or defects, may not be put into use. Other parts, such as hook, wheel, pull plate defects, does not meet the requirements, are not allowed to use. (6) the door pulley in use only a few doors, its weight should be reduced accordingly commuted from, not upon the original starting weight.
