New bridge over China’s Yi River

A new bridge has been built in China that now spans the Yi River. A crane from XCMG has played a key role in the work, being used to erect the two 100m-high towers for the structure.

A new bridge has been built in China that now spans the Yi River. A crane from 2490 XCMG has played a key role in the work, being used to erect the two 100m-high towers for the structure. The bridge is made from prestressed concrete and is a cable-stayed structure, with two towers providing support for the necessary cables. Building this large bridge required the use of sophisticated technology and the project team opted to use a 100m-high tower crane to help lift key elements of the structure into place.

The construction team also employed a large all-terrain crane, with a maximum hoisting capacity of 500tonnes. An XCMG QAY500 model was selected for the work, with power from a Mercedes Benz diesel engine and featuring seven boom sections with a length of 84m when extended. The crane can also be rigged with fixed king-size jibs of 56m, luffing jibs of 91m and a Y-shaped superlift structure, with torque up to 2800Nm.  A key feature of the crane is its dynamic matching hoisting technology as well as its intelligent operation system. Despite its large capacity, the machine also has a comparatively compact design and its chassis configuration allows a minimum turning radius of 15m. This allowed the crane to turn round in the confined construction site under the bridge.
