, PT7040



The PT7040 flat top tower crane consists of a metal structure, hydraulic jack-up, electric controls and safety protection devices. With its high performance, the topless tower crane saves users time and money.

Features of the Flat Top Tower Crane
Low overall height (multiple crane sites)
Easy and safe to raise, lower, and assemble jib
Jib configuration can be easily modified during a work project, elevated or dismantled in the air, section by section.
Hoisting and trolley ropes installed on the ground, plug-in connections for electrical equipment and safety devices keeps the flat top tower crane working safely and efficiently.
Variable frequency slewing and continuously variable speed control by means of a stepless controller that also adapts to the operator's driving style.
Variable frequency hoisting and continuously adjustable speed optimized depending on the load being handled. Slow speeds and smooth changes increase productivity.
Using standard bases, the tower crane masts can be adjusted to a desired height
The adjustable bases provide options for installing: on fixed angles, on the cross-shaped base, on traveling gear, or leave it as a climbing crane.
