Thruster Rail Clamp

Thruster rail clamps

Thruster rail clamps are used in moving machines like travelling trippers of coal handlingrnplant, gantry cranes and semi gantry cranes. Thruster rail clamp is attached to the travellingrnbogie of the moving machine one or two numbers per rail. in case of travelling tripper, even though it is stopped by shutting off the drive, the running tripper belt drags the tripper on the rail. To avoid this dragging, thruster rail clamps are used. In case of gantry and semi gantry cranes, thruster rail clamps are used to hold the cranes to the rail in case of storm and avoid toppling. Operation of thruster rail clamp – when the machine power is put on, the thruster operates, opening the clamp against spring force and the machine moves freely on the rail. When the power to machine is shut, thruster is shut, closing the clamps on the rail with the spring force. Depending upon the clamping force required, following models are available -

No.    Model    clamping force  thruster    thruster stroke

1.     TRC 500       500 kg           50 kg    50 mm

2.     TRC 1000    1000 kg          80 kg     50 mm

3.     TRC 2000    2000 kg         120 kg    60 mm

4.     TRC 3000    3000 kg         200 kg    60 mm

5.     TRC 5000    5000 kg         300 kg    60 mm

Tailor made design of thruster rail clamp is also possible.
