Brief Instroduction:
Its rated lifting capacity is as following: 60t, 80t, 100t, 150t, etc.
It can lift the precast bridge girder for the long traveling and cross travelling, to lay the straight bridge, skew bridge, curved bridge, heavy grade bridge, etc.
Working principal: By making use of the counterbalance, the rector moves on the rail and makes one end connect to the bridge pier; and then the bridge erector lift the precast bridge girder and complete the laying. The whole process is safe and convenient.
