Its length can be adjusted according to working face location change of belt conveyor.

Suitable for mining face along the groove in the transportation and transport tunneling faces. It through the fuselage set of belt and the take-up device makes storage within the scope of a certain length does not answer the conveyer belt can change its laid length, thus and reproduced machine with rapid advance to adapt to the coal mining face or the requirement of quick tunneling drivage working face, reduce the operation time removed conveyor.

Extensible belt conveyor is big conveying capacity and single length in the direction of development, its throughput reached 2000 t/h, stand-alone laying length of 3000 m of the telescopic belt conveyor technology parameters:

 1) the throughput can be divided into 100, 200, 400, 200, 800, 1000, seven of 1200 t/h.

2) belt speed can be divided into 2, 2.5, 1.6 and 1.9, 3.15 m/s five.

3) drive roller diameter can be divided into 500, 630, 800, 1000 mm.

4) motor power is divided into 22 * 2, 2, 75, 75, 40 * * 2, 40, 90, 125, 160, 2, 200 * 160 * 2, etc. 10
