With the increasing degree of lifting mechanization, the wide application of equipment not only speeds up the construction progress, but also improves the construction quality. Because crane equipment is affected by various factors in the daily use process, it will lead to the inadequate performanceREAD MORE

The main beam of the trailer is the main component of the semi-trailer, and there are many vertical auxiliary beams near the beam. The main beam and the auxiliary beam constitute the entire cargo consignment platform of the semi-trailer. There will be broken beams and other traffic accidents.Here is
A general drum brake is composed of a rotating part, a fixed part, an actuating part and a positioning adjustment device. It is composed of brake base plate, brake cylinder, brake shoe and other related connecting rods, springs, pin nails, and brake drum. Only generally used on the rear wheels.The a
Trailer height refers to the height of the trailer-mounted cargo platform. Since the trailer is a hydraulic independent suspension, which corresponds to the maximum stroke position and the minimum stroke position of the suspension hydraulic cylinder, the height of the trailer can be adjusted within a certain range. The height of the trailer is often expressed in the form of d±e (as shown in the figure below). For example, a trailer is marked as 1190mm±325mm. Among them, d is the normal operating height of the trailer, generally the distance from the midpoint of the trailer's lift to the ground, and e is 1/2 of the trailer's lift, which is also called the trailer's lift.
The trailer suspension is supported by a hydraulic cylinder. When the hydraulic cylinder is lifted to the limit position, the hydraulic support will be lost due to the mechanical limit in the cylinder, which will easily cause the suspension to lose its hydraulic balance and cause overload. The limit height used should have a certain margin. Sometimes there are high-altitude obstacles on the transportation road, and it is necessary to accurately calculate the minimum running height of the trailer loaded with cargo. At this time, the tire deformation caused by different loads and the impact of the flatness of the trailer's cargo platform should be considered, and a certain margin should be left. the amount.
