Technical Advantages
1. D1250-80 super large tower crane has the longest working range nowadays in the world. Its working radius can reach 110 m.
2. This tower crane adopts advanced double step progressive type variable cross-section arm frame system, which greatly improves lifting jib lateral stability and lifting capacity.
3. The maximum lifting capacity creates a new record—as heavy as 80 t. Compared with tower crane of the same lifting torque, the maximum lifting capacity has been increased by 26.9%.
4. With the first rotary adaptive control patented technology, hoisting, luffing and swing mechanisms employ constant power speed regulating mode, making D1250-80 tower crane work with high efficiency. It can shift 6 t weights to 220 m within two minutes.
5. The first animated version installation manual for tower crane in the world is provided, making it faster, better and safer to install the crane.
