Product Details
Introduction:
When the main engine is shut down, the rail claming device automatically clamps the rails to ensure that the main engine is not blown away by strong wind. When the main engine needs to move, the hydraulic device opens the clamp to ensure that the main engine runs freely on the track.
Product application
Spring type rail clamping device is a safety device to prevent the rail crane from moving freely along the rail direction. It is applicable to large freight yards,various bridge and gantry cranes. When the main engine is shut down, the rail claming device automatically clamps the rails to ensure that the main engine is not blown away by strong wind. When the main engine needs to move, the hydraulic device opens the clamp to ensure that the main engine runs freely on the track.
Main features
The clamping force of the spring type rail clamp takes the spring as kinetic energy to clamp the rail through the beam,contecting rod and clamp.
The opening of the rail clamping device jaw depends on its own hydraulic system. Its working mode is: through the rail clamping device control curcuit, before the main machine travelling mechanism starts to travel, only the power supply of the oil pump motor and solenoid valve of the rail clamping deviceis connected to let hydraulic oil enter the front chamber of the oil cylinder, push the piston, compress the spring, and open the jaw.
After the nipper leg is fully opened, the power supply of the oil pump motor is cut off by the limit switch (the solenoid valve remains energized), and the linage circuit of the crane travelling motor is connected, and the crane starts to travel.
After the power of the oil pump motor is cut off, the hydraulic system ensures that the jaw is always open due to the pressure maintaining effect of the one-way valve and the solenoid valve.
