MECHANICAL FOLDING TRACKS

DoorHan mechanical folding tracks are intended for loading and unloading operations; are installed on open ramps, compensating the height difference between the truck and the dock of up to 360 mm. Designed to be used with vehicles having approximately the same height. During handling operations the track is lowered into the vehicle body using the side handle until the lip reaches the floor. After the work is completed the track is raised and returns to its original position. Mechanical folding tracks FT Series may have a fixed or sliding design. The track, which has a sliding design, allows to work alternately in several places on the ramp, due to its mobility along the guide rail from one point to another. The mechanical folding track is installed on a prepared ramp. DoorHan mechanical folding tracks meet the requirements of standards and guidelines DIN EN1398, are certified and have certificates of conformity.

Main advantages:

availability of lock, that locks the track in a vertical position;
due to yellow-black signal strip, one can see that the platform is above the level of the ramp;
the possibility to move the track (for mobile tracks).

Construction

The surface of sliding mechanical folding tracks is made of embossed steel sheet with a thickness of 5 mm, where the embossing height is 0.5-1.5 mm and is designed for loading and unloading operations using a standard forklift. There might be a potential deformation of the track surface, which does not affect product operation. The lip is made of embossed steel sheet of 12 mm thickness, where the embossing height is 1,2-3,6 mm. Track girders are made of pipe with the following dimensions 60x40x3 mm. Mechanical folding tracks have balancing lever mechanism, based on 2 springs and roller bearing. Guide rail is made of hot-rolled U-shaped profile of 160 mm.
