Introduce:

The segment car is mainly for transport segment into the tunnel during shield construct,also transport materials. Include car body,walking part, etc. On two ends equiped with shaft pin traction joint plate, connect with tunnel locomotive. At present, has load for 10~35t,customised by client's require.

Segment car as the auxiliary equipment in shield machine construction, mainly used for transporting segment and materials.According to the different operating stations and enhance the braking capacity, manual braking devices are divided into vertical and horizontal forms.In order to ensure the stability and safety of the segment transportation process, set 30mm rubber anti-skid between the segment car and  "U" car body.The segment car use two axle bearing box walking device, on the two axle box two side sets  of compound rubber spring, which not only improves the stability of the segment car, but also greatly extends the service life of the bearing.The car has two optional braking modes, simple structure and convenient maintenance.

Structure:

Car body: The segment car body are weld on the frame, in order to adapt to the positioning of the segment, the segment car body is designed to be inclined structure.The touch inclined face between segment and car body, has set a 30mm rubber cushion to avoid the hard touch and wear between the segment on the car.The body surface is covered with anti-slip steel plates.

Walking part: the bearing is installed in the wheel walking mechanism. There are two sets of rubber damping at the upper part of the axle fixing seat, which improves the stability of car walking and greatly extends the life of the bearing.
Hand braking system: designed to meet the requirements of shield construction and to prevent sliding.

Advantage:

1. Box structure, large capacity

2. High rigidity, spring rubber damping

3. Has rubber cushion, avoid hard touching and friction

4. Hand brake for anti-slide function

5. air braking, wilson coupling and safe chain
