The service: Providing high quality product, timely delivery, full set of spare parts, warranty for 12 months,

training of installation guidance, operation and maintenance

The safety: it has lifting height limiter, dolly range-change limiter, moment limiter, weight limiter, slewing limiter, etc.

3: Application field:Building height 60 floors (180m),loading capacity10t, building length 60m or 70m. If you havespecial requirements, we willdesign new typefor you

4: The features

1) The hydraulic climbing system

It adopts standard section hydraulic lifting and connecting, and can decide the crane height according to the actual height of the building, The max. attached height can reach 180m

2) The lifting mechanism

The coiling frequency motor and mono-speed ratio decelerator is applied in the lifting mechanism, which enables heavy load low speed and light load high speed

3) The trolleying mechanism

The range-change structure drives the dolly to change range on the horizontal arm, with good positioning performance

4) The slewing mechanism

Planet gear decelerator is used in the slewing structure, together with moment-limiting hydraulic coupler, which ensure high load capacity, steady starting and reliable operation
