Safety protection device of rail mounted gantry crane-Buffer
As we all known, in order to ensure the safe operation of single girder gantry cranes, various safety protection devices need to be installed. Among them, buffers are essential.
How many kinds of buffer equipment of cabin control gantry cranes? Let us have a look together. The buffer devices of gantry cranes are usually divided into three types: spring buffers, hydraulic buffers, and physical buffers.
Spring buffer: This kind of rail mounted gantry crane buffer is mainly composed of spring, shell and bumper. When the single girder gantry crane hits the spring buffer, it converts the energy into spring compression energy
Hydraulic buffer device: When the 20ton gantry crane collides with the buffer, it allows all crane parts to go through a process to achieve the purpose of buffering, thereby reducing the possibility of harm.
Physical buffer of heavy duty crane: It is divided into two types: rubber type and polyurethane type. The rubber buffer of portable gantry crane has the advantage like ,simple structure, convenient installation and maintenance, low price, and long service life. The polyurethane buffer of mobile gantry crane is more adaptable and has a wider range of applications.
The above are three types of rail mounted gantry crane buffers. Hoping everyone can choose suitable buffers according to your needs. Should you have any other questions of gantry crane safety protection device, please leave a message or write email to us.
