Yuntian ship-mounted slewing crane is also called marine crane and it is a kind of ship deck machinery, it used to goods loading and unloading. This kind of crane structure is compact which makes the ship deck area more available. The influence to sign of fore bridge upstair is small. The operation is easy, high efficiency, loading fast and no preparations before work and with wide application. The main design basis is China classification society CCS “ Rules for lifting appliances of ship and offshore installations” GB/T 3811-2008” Design rules for cranes”.
Company welders have passed the CCS welder's examination and practical opertion certification, and drawings have gotten CCS audit and approval. Meanwhile,we establish the largest domestic deck crane inspection and detection platform.
1.It has built-in machine,electricity and hydrulic integrated system, using full hydraulic-driven method to maintenance intelligently.
2. It uses automatic diagnostic wave compensation system to ensure the object don’t slip when the hull is subjected to wave impact.
3. The horizontal movement technology of luffing object is used to ensure that the hanging objects move horizontally, without drifting up and down in the process of boom luffing operation.
4. All institutions built into the tower drum, eight safety devices including the torque limiter etc and visual safety monitoring system are used to ensure cranes’s good operation.
5. Easy operation, high handling efficiency, wide application.
