Advantages
The SF120L luffing jib crane adopts a large variety of advanced technologies with sophisticated mechanisms including the hydraulic self-propelling mechanism and frequency converting slewing mechanism. With advanced PLC (Programmable Logic Controller) and frequency converter, this construction crane can realize continuously variable frequency speed control and get immediately inspected and diagnosed when a fault happens.

Due to the hoist height limiter, slewing range limiter, multifunctional limiter and other reliable safety devices, this luffing jib crane can easily manage the load moment, hoisting capacity and trolley traveling range. Also, the electric safety devices like anemoscopes and obstacle lights and mechanical safety device also prevent the breaking of trolley axles and wire ropes, adding to the degree of safety.

The electric control system is more reliable, stable and maneuverable, and the work efficiency of the tower crane is also significantly improved. In addition, most electric components of our luffing jib crane are procured from world-renowned companies, such as Omron, YASKAWA, Schneider (Te) and Mean Well. They effectively reduce the failure rate of the electric control system.
