MH-type gantry crane slewing mechanism meter loop installation steps

1 in the lower supporting  overhead gantry crane  installation, check the gear overhanging upper beam seat surface shall be horizontal, tilt is not greater than 0.02mm, the lower support bearings cleaned and inject grease sealed cover after hoisting , and bolted. Then hoisting gear ring, playing Key and tighten the screws into place, it can be lifted under the rotating platform set into the lower support shaft to adjust the next rotating platform appear before the upper horizontal flange. The lower slewing platform pad stability and welding reinforcement.

2 rotary column test equipment, rotary column before installation should lie flat with the outer wall of the axial elements draw lines in order to arm bearing, bearing on the rotating platform, rod bearings installed in place of the positioning reference.

3 will be transferred to the next column hoisting and slewing platform flanged bolts fastening portion; looking forward to adjust the center column, vertical compliance after reinforcement.

4 would arm bearing, shaft hole horizontal centerline and distance control with the flange surface within its design limits, allowable deviation compliance, the bearing and the shaft pillar welded into one.

5 would be on the rotating platform bearing, shaft hole horizontal centerline distance control with the flange in the design range, bearing and rotary column welded into one.

6  hoist gantry crane   will rod bearing, shaft centerline hole horizontal transfer cylinders with distance control in the design range, bearing and rotary column into one.

7 Remove the rotary column packed trial will turn on the rotating platform and hoisting column together into a whole. Looking forward vertical column, fastening rotary column and the next rotating platform flange bolts, and then will be transferred to the Ministry column support structure fixed.

8 on the rotary mechanism gear box, reel, motors, brakes, after passing the examination, according to plans designed to correspond to the positions in place. Pair of gears, couplings, brake adjustments and comply with the relevant requirements.

9  bridge gantry crane   will go to Taiwan, human ladder pulley mounted on the boom, the overall boom lift and lower bearing rotary column connections. Lift the lever and turn the column portion bearing connection, check the boom angle, the bearing, shaft pin connections are secure and meet the requirements of the drawings.
