Anti-derailment measures and installation steps of rail type lifting freight elevator


1. The equipment and level of the underframe (base) of the rail type lifting freight elevator are leveled. Place the jack-up way in place so that the center line of the frame coincides with the center line of the column.

2. Put the rod equipment on the self-lifting path and wear the wire rope. The first column of the equipment list, the standard section is placed in the sleeve, and the base is bolted. Adjust the net distance of the column rail surface to be within 1985mm, and the straightness error should be ≤1.5‰.

3. Place the advancing pulley on top of the two uprights of the equipment and pass the advancing steel rope. Use electric winch to advance self-lifting way. Retract the elastic card to the fixed position until the bottom of the elastic card is flush with the top of the top surface of the column, reset the elastic card board, loosen the advancing wire rope, remove the advancing pulley and place it on the way.

4. Use the second standard section of the rod equipment. Before tightening the bolts, make sure that the first group and the second group are on the same straight line, the error at the joint is less than 0.5mm, and then place the forward pulley on the top of the second standard section. Wear the forward wire rope. Equipment, fixed weight beams.

5. The equipment reinforces the diagonal braces, and tightens the connecting bolts of the above pieces. Check the good standard section of the rail-type lifting freight elevator equipment, adjust it to meet the requirements.

6. Check whether the pressure (or arrange the weight) connection is reliable. Equipment hoist, and set grounding equipment according to rules.

7. Put in the gondola, wrap the wire rope, and link the safety equipment. At this time, the bottom equipment of the rail-type lifting freight elevator is well organized. Send the third set of standard sections into the gondola, advance the gondola to near the limit height, then install the third set of standard sections with rods, place the forward pulley on top of the third set of standard sections, and repeat process 6 forward path.

8. Raise the use height of the gantry. At the corresponding height, the equipment rail type lifting freight elevator and the parking bracket can be put into trial operation. When the lifting height of the gantry rises to 6m, the first track should be set to attach, and then one every 3m.
