Problem hoist rails might encounter

The vast majority of metallurgical hoist crane is installed on a handful of fixed rail. Before installing hoist rail beam must first understand the type, length, with or without seams, with or without bumper and grounded. Only rail model and implement a mechanism to be able to adjust to run the installation space. If the rail is too long and way too weld the best in the "front rail lifting" the welds polished to avoid future rail and hoists are installed after the completion of the sports car appeared blocked walking "slip" or even "bounce" that could not explosion proof hoist Road, rail joints smoothly beyond the situation. Treatment could have increased the difficulty of solving the problem on the ground have had to deal with starting the fire and aerial job ticket, fill paint corrosion occurs only cause duplicate scaffolding erection problems also added a safety hazard. Road, rail Although it is not our work, but I think we all know that "interdependent", "gates of fire adverse impacts to fish," the truth. This requires that we implement on-site technicians often run rail installation progress and keep good communication with technicians brothers rail mounted unit is responsible for the post-commissioning, acceptance of work to do preliminary groundwork. Otherwise, when the relevant technical personnel responsible for the installation of rail have been removed from this work truly become "historical issues" after dealing with them is extremely difficult.
Besides bumper. In many cases the ends of the bumper rail away from walls and other equipment or buildings too close to explosion proof electric hoist the body longer and therefore they are easily accessible in the welding bumper level best to hoist the end face of the front wheel from the car to walk the distance as bumper welding actual position basis. Often a lot of cars stand in front of the factory rail welding is completed, but the actual site conditions must prevail before lifting. To avoid the trouble to produce bumper complete transformation of the ground and do the best are embalmed. Some bumper design a buffer or cushion rubber block of wood which requires that we must be optimistic about the drawings are often not so fine for content on our own installation crew received the drawings, it is necessary to consult other departments on rail details condition. In the transfer of rail when we must implement the above, or not receive.
