Potains in Shenzen

22 September 2020

China Construction Seventh Engineering Division has deployed two Potain MCH 175 cranes (badged as MCH 170 in China) to projects in Shenzhen.

One is working on a fire station project on Jingtian Road and the other is on a housing project on Panlong Road. The projects are part of the Chinese government’s effort to transform Shenzhen into a global business center by 2025.

“We selected Potain cranes because they are the top tower cranes in the industry and we are fans of the MCH 175’s VVH hydraulic luffing system. The crane has a short out-of-service radius which makes it easy to work in tight spaces, such as downtown construction sites,” said Ma Guihong, chief engineer, China Construction Seventh Engineering Division.

Both cranes are new additions for China Construction Seventh Engineering Division and were deployed to their projects in early February. On the fire station project, the first MCH 175 has a 35m jib at 80m working height. The second MCH 175 is configured with a 35m jib at 130m working height. Both are expected to remain on site until early 2021.

One of the MCH 175’s has a VVH hydraulic luffing technology which can move the jib from horizontal to 87° in less than two minutes and also eliminates the need for luffing ropes.

“To reduce on-site assembly time, the crane’s hydraulics were pre-connected at the factory. The hydraulic cylinder that powers the luffing motion offers lower energy consumption than conventional luffing jib cranes. This means it requires a smaller generator, lowering costs for owners,” said Manitowoc.
The MCH 175 has a maximum capacity of 10t, maximum radius of 55m, and maximum tip capacity of 1.5t.
