Product Features:

This product is a special lifting system matched with the TBM. It can be customized according to the diameter of the cutter head of the TBM and the actual working conditions and can realize the lifting of single or multiple segments and box culverts. The segment crane is featured with compact structure, stable lifting and accurate positioning. It has the functions of PLC control, hydraulic grasping, automatic acceleration and deceleration, safety interlock, mechanical positioning, slope climbing, over hinge point, safety braking, etc.

Inching movement
Ensure that the crane moves slowly and accurately as it approaches its destination. This function can be applied to hoisting mechanism, trolley and crab. Inching movement can be set as required.
Dead slow
Dead slow function can ensure the stability of the control system and slow, accurate movement when the crane is moving and loading. This function can be applied to hoisting mechanism, trolley and crab.
Zero speed hover
"Zero speed hover" function automatically starts to prevent slip hook when the control system detects the slip hook trend (the motor does not rotate when the brake is opened).
Impact-proof
Our cranes are all equipped with functions of upper pre-limit, upper limit, top impact-proof limit impact-proof of the crane, which meets various needs of customers for products.
Electric anti-sway function
Crane can automatically limit the sway of the loader in the process of handling, realizing faster handling and more accurate positioning, and to be stable during the handling process.

Regional load limit
Cranes are equipped with hazardous area restriction function, which can reduce the dangerous situation during loader movement, and prevent the damage of the loader, crane and surrounding area facilities.
Speed expansion function
Our cranes can add sub-low speed and sub-high speed function regulation except for low speed and high speed, which is practical and efficient.
Multi-hook coordination
The crane can monitor and control position difference of multiple hooks to make the hooks run synchronously at the same speed, ensuring the efficiency and quality of the crane.
Multi-trolley synchronization
When multiple cranes lift a loader at the same time, the position difference of multiple cranes can be monitored and controlled to make the crane operating mechanism run synchronously at the same speed.
Wireless expansion
A wireless module can be added to the crane to connect to the Crane Industrial Internet Platform, realizing the full life cycle management of the crane.
