Nov 01, 2016

Installation preparation

1. Laying crane track

According to the crane installation site plans, determine crane track position, dig a ditch deep 300 ~ 400mm, width 1.5m, then cushion ballast, ballast thickness is not less than 600mm, laying sleepers, rails.

2. Laying steel pipe at the track outside, and then joined them together with flat iron, grounding resistance should not exceed 4Ω.

3. Traveling mechanism, lifting mechanism overhaul.

4. Bridge body assembly.

Crane body traveling mechanism installation

Put two units traveling mechanism on the track, two carriages diagonal error is not larger than 5mm.
 

Install support leg

Place four support leg on the traveling mechainsm by number, connect them with bolted. Then use wind cable rope to fix four legs, prevent dumping. Adjust suppot lefs by chain block, to make sure its center line is perpendicular to horizontal.
 

Install main beam

Place the main beam on the sleepers (sleeper stack height about 1m), remove electric hoist one side car stop, lift the hoist and install the hoist into track from one end, then recover car stop. Use truck crane lift main beam, place on support legs, connect by bolts.

Then hang the lifting mechanism.
 

Wire Recovery

1. Connect the power cable, control cable well.

2. Recover safety limit devices, including crane traveling limiter, electric hoist traveling limiter, electric hoist lifting height limiter.
 

Load testing

Do this as " Double Girder Gantry Crane Load Test "
