Whether it is a variety of cranes or traveling cranes in the installation and maintenance process, they need to strictly abide by the construction requirements of special equipment to operate, so as to ensure the safety and stability of the equipment operation. Let me share some of the problems frequently encountered during crane maintenance.
Mobile cantilever cranes and crane lifting systems are used to install cranes. Use a mobile cantilever crane or other hoisting machinery to install the crane. For general cranes, such as general bridge cranes and gantry cranes, mobile cranes can complete the installation tasks independently.
Check the condition of the pulley frequently and maintain a proper gap between the pulley and the outer contour of other objects. If the gap is too small, the cover will be worn by the pulleys. If the gap is too large, the wire rope will loosen out of the groove or be clamped between the cover and the rim of the pulley. On the lifting balance beam and the wedge shell exit of the closing mechanism pulley block, it is easy to bite or cut the wire rope. The smoothness of the rounded corners at the wedge shell exit should be checked frequently. If it is rough or sharp edges have been ground, it must be rounded. Refile the corners smoothly.
Cantilever crane double beam gantry crane flower frame crane is a new type of material lifting equipment developed on the basis of pilaster cantilever crane. The crawler device of this machine is on the concrete column of the workshop, which can move longitudinally along the crawler. The electric hoist can complete horizontal movement and linear lifting along the cantilever. The machine greatly expands the scale of work, makes more effective use of workshop space, and makes the use more ideal.
After the work is finished, park the trolley at the end of the main beam, away from the sliding contact line of the trolley, and do not stop in the middle of the span; the trolley should be driven to a fixed parking position. The crane hook should be raised to a height close to the upper limit position, and lifting appliances and objects are not allowed to be hoisted. For the electromagnetic suction cup grab crane, the suction cup or grab should be placed on the ground and not suspended. Return all controller handles to the zero position, place the emergency switch in the open state, and pull down the knife switch of the power cabinet. The driver should inspect the crane at the end of get off work, and record the problem and the inspection in the handover record book, especially the unsafe factors, and hand it over to the follow-up personnel.
