Description of QTZ40 Internal Climbing Tower Crane
Internal climbing tower crane adopts hydraulic climbing method, usually installed inside the building elevator. The working radius is fully utilized and so the working range is wide, valid hoisting capacity is strong compared to external climbing tower crane.
The crane climbs with the increase of the building height. The maximum hoisting height is 120m and standard mast height is only 26.4 m, which saves lots of purchasing cost, transportation fees and maintenance expenses.
