Average winter temperature is low, manual hoist is more need some lubrication and maintenance to ensure smooth operations. In cold operating environment operation, if irregularly inspect hoist maintenance and lubrication will lead to all parts subject to wear chain hoists , chain hoists not only severely shorten the life , but also may lead to accidents . Chain hoists winter maintenance : 1 , manual liftech single girder chain hoist maintenance is a top priority , it is timely for the chain lubrication. 2, such as long-term placement , should be handled in a timely manner and rust cleaning and maintenance work and test run to see if it is working properly . 3 , regular maintenance manual hoist the main parts detection , and resolutely put an end to security risks liftech 1 ton chain hoist appear. 4 , brake parts should be kept clean , cut out regular checks to prevent sudden Zhidongshiling work occurred weights from falling . 5, using the manual hoist rain , rain facilities should be set up . 6 , keeping dry parts chain hoists , chain hoists place after the operation is completed dry steel beam clamps environment . Avoid high temperature and chemical areas.Chain hoists friction plate is one of the very important parts chain hoists , chain is inverted indispensable constituent elements , but also one of the main wearing parts. Its role is to tightly engage the friction stability and prevent the emergence of the phenomenon of chain hoists decline .Long chain hoists three friction plates using the latest advanced technology, the friction surface to join wire to increase the coefficient of friction to ensure the stability of the friction plate friction , long life , safety , and as one of the main wearing parts chain hoists , chain hoists easy to replace the friction plate conducive maintenance.
