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.
