High-Strength Steel Double Beam Overhead Crane Machine For Industrial Lifting
Product Introduction
The structural feature of the double girder bridge overhead crane is that the trolley with the lifting and operating mechanism runs on the bridge frame, and the metal structure is in the form of box-shaped double main girders. According to the characteristics of the pick-up device, it is classified into hook, grab, electromagnetic and multi-purpose bridge cranes, which are mainly used in frequent material handling stations such as mines, factories, docks and warehouses. As a heat treatment process equipment, the quenching crane has the characteristics of high-speed descent. Metallurgical foundry cranes are suitable for transporting steel ladles and are essential equipment for the smelting industry. Using modern technology means, any mechanism of the crane can be equipped with speed regulation performance. It can also be equipped with a rotary hook for high-level stacking operations.
There are two common rail fixing methods for overhead cranes.
1. Welding and fixing method of pressure plate
Pressure plate welding uses electric welding and pressure plate to fix the track on the load beam. This welding method can ensure that the track is not loosened and displaced, but it is troublesome to disassemble or transfer the track. The pressing plate must be cut off, and it cannot be recycled again. Once the bridge crane is assembled, it is rarely disassembled, so there are currently many ways to use pressure plate welding.
2. High-strength bolt fixing method
This way is a way to fix the track on the load-bearing beam by using the track pressure plate of the bridge crane and high-strength bolts. High-strength bolts must have washers and spring pads, otherwise they are easy to loosen. Since this fixing method is prone to loosening, it is necessary to check and fasten the bolts frequently.
