Braking device**-make sure the shelf fully locked,not moving.

Catalog card**-easy and convenient to sort out file name.

Rubber sealing strip**-with a buffer and sealing function.
 

The cranking bar**-small wheel,big strength.

The shelf has been tested to prove that the ratio of the driving force and the loading weight is 1:***0, that is, the strength of 1kg is enough to drive the load of ***0kg;
 

Chains : *2.7 pitch roller chains. Manufacture according to GB******9 and 1/2national standard. Strong traction, small friction, high transmission efficiency.

Track: Skidproof device on the bottom can eliminate the derailment and dumping in the operation.
 

Rolling wheel : High quality *5# steel forging, CNC lathe precision machining, high concentricity. The bottom surface of the groove is connected with the track through the R*6 angle processing technology to achieve a smooth and stable walking.

Transmission mechanism by using **8 type motorcycle chains and precision plane bearings, runs felxible and smooth. The match of shelf board and the support plane of hook is firm and stable and the space of layers is also free to be adjusted according to need. Braking device and steel lock equipped by each row are in order to keep the whole lock.
