Double girder overhead crane is a type of lifting equipment and is an important tool and equipment for mechanization and automation of the production process in modern industrial production and lifting transportation. Therefore, the double girder bridge cranes are widely used in indoor and outdoor industrial and mining enterprises, steel and chemical industry, railway transportation, port terminals and logistics turnover departments.
Bridge cranes have double girder bridge cranes, single girder overhead cranes, and semi gantry crane operating procedures. Each has a different operating procedure. For example, double girder bridge cranes, before the work, check the brakes, hooks, wire ropes and safety devices according to the requirements of the check card, and find abnormal phenomena, which should be excluded. Secondly, the operator must close the main power supply when confirming that there is no one on the platform or track. When the power circuit breaker is locked or has a sign, it should be removed by the original person concerned to close the main power.
When lifting the heavy object for the first time in the work (or when the load reaches the maximum weight), the weight should be put down after lifting the height of 0.5 m from the ground, check the performance of the brake, confirm the reliability, and then carry out the normal operation. During the operation, the operator shall ring the alarm for the following items as required. 1. Lifting and landing heavy objects; when driving large and small trolleys. 2. When the crane is driving, when the line of sight is unclear, it is necessary to continuously ring the alarm; 3. when the crane is approaching another crane in the span. There are still many major places when hoisting heavy objects close to people. Of course, in addition to the pre-work, work and some post-work notes and operating procedures are all need to be remembered.
