Hello,

Yes,there was once a Richier GT1427,on older type of crane.
This could lift 40 tons by 8 ropes and was an heavier part deraved from the Weitz G280.
(these cranes were used at the construction site of the Royal Opera House in Sydney).

Thanks for these data. Have you the data sheet of this crane? Could you send it to my mail adress? I am interested especcialy by the maximum hook height for rail going version and the dimensions of mast(tower square).Greetings.

Five MQ2000 with double lever boom were engaged at the massive Three Gorges project with up to 100m hook height on rail travelling portal and 71m maximum working radius. These cranes were manufactured for the first time in 1996. Sometimes they are dubbed high frame portal cranes, but actually they are a speccial sort of tower cranes.

For the mega dam project Three Gorges, meanwhile, Shanghai Port Machinery Plant built five giant MQ2000 ?high frame portal cranes?. The bottom climbing cranes are equipped with double lever jib to deliver 20t concrete buckets at a radius up to 71m. Design integrated horizontal movement of the hook during luffing and speedy luffing are essential for this heavy-duty job. At 35m radius, 63t can be lifted. Although 100m under hook height can be achieved, the crane is based on a rail going portal. The required dimensions of the machine lead to a rigging time and size of the crane components only acceptable for long running industrial construction projects.
