Misunderstandings in the use of gantry cranes

Gantry cranes are important construction equipment for construction and equipment installation, especially in the construction of modern high-rise buildings. At the same time, as a special operation equipment, its safety problems are becoming more and more prominent in front of us. Therefore, we need to first understand the use of equipment and possible misunderstandings in order to reduce or avoid the occurrence of security accidents.

Myth 1: Gantry cranes have a lot of oil. The oil in the crankcase of the crane cannot be added too much, not less. Too much oil bubbles can add to the shifting resistance of the crank linkage and add oil to the cylinder walls. Excess oil will cause carbon deposits to build up in the combustion chamber and engine power will be cut, which affects emissions. When checking or adding oil, the owner should add according to the plan of the oil plan. The oil level should not exceed the upper limit of the ratio and should not fall below the standard lower line. The oil level is usually added to the upper center of the two gauge. Orientation is appropriate.

Myth 2: Gantry crane attachment belts are rather tight, not loose. Some car owners believe that increasing the tension of the accessory belt can improve the cooling effect of the compressor and the power generation of the generator, so they continue to increase the tension of the belt, but they do not realize that this method is wrong. The accessory strap should be properly tightened. Because the belt is too tight, the bearing will be overloaded, which will shorten the service life of the components and cause cracks in the belt, which will eventually affect the normal operation of the crane.

Myth 3: Gantry cranes are often waxed. Wake up too frequently, wax the crane often, and while it will make the paint more shiny, it will cause damage to the car. Because the car wax contains alkaline substances, long-term use will make the car body black.
