A gantry crane is a type of portal crane commonly used in factories for lifting and processing goods. This gantry crane incorporates both domestic and international technologies and manufacturing techniques, as well as being designed taking various working environments into account. It offers improved performance in lifting goods, features a unique structural design that ensures compactness, enables the lifting and processing of goods, and provides high work efficiency with low energy consumption and excellent results. To ensure the proper operation of the gantry crane during disassembly and relocation, it is necessary to align it correctly during installation. Next, the container gantry crane manufacturers will explain how to achieve this alignment. Installation of tracks and car stops. Before laying the rails, it is necessary to first check the end face straightness and distortion of the rails; they can only be laid after passing these checks. Before installing the lifting rails, it is necessary to determine the installation reference line for these rails; this reference line should preferably be the alignment axis of the crane beam. The horizontal deviation of the actual track alignment from the installation reference line shall not exceed 5 mm; for beam-type suspension cranes, it shall not exceed 3 mm. Maintenance methods for gantry cranes: 1. Lubrication – The operational performance and lifespan of various components of the crane depend to a large extent on lubrication. During lubrication, refer to the manufacturer’s instructions for the maintenance and lubrication of electromechanical devices. Equipment such as traveling cranes and lifting gantries should have lubricant applied to them once a week. Attention should be paid to the broken wires in the steel wire rope. If there are broken wires, broken strands, or the wear level reaches the standard for replacement, a new rope should be installed promptly. 2. Regular inspection of the lifting gear. 3. For pulley blocks, the main things to check are the wear of the rope grooves, whether there is any cracking on the rim of the pulleys, and whether the pulleys are stuck in their shafts. 4. During regular inspections of the wheels, check the rim and tread; when the wear or damage to the rim reaches a certain thickness, it is necessary to replace the wheel with a new one. 5. The brakes should be checked once per shift. The brakes should operate accurately, and there must be no sticking of the pins. The brake shoes should fit the brake wheels properly, and the gap between the brake shoes should be equal when the brake is released.
