Zoomlion ZCC550H Crawler crane

Strong lifting capacity：

● Large Gauge Track Chassis Guarantee 360°Excellent overall stability in the swing range，**The large lifting moment is 209t·m，Under the condition of fixed jib**Large lifting capacity of 12.0t。

● Main arm**The large length is 52m，Main arm+Fix the fly jib**The large length is 43m+15m。

And that universality of the part is good：

Products on the same platform are common except for most electrical components and hydraulic components.，The structural members are also largely interchangeable，Uch as a fixed jib、Goose head rack、Hook、Luffing mechanism、Counterweight base, etc.，Significantly reduce purchase and maintenance costs。

Security protection is comprehensive：

Torque limiter as standard、Lifting height limiter、Main boom angle limiter、Over-discharge protection device for steel wire rope、Amplitude-variable win ratchet wheel locking mechanism、Anti-roll back device、Anemometer、Aviation warning light、Tricolor warning light、A series of safety devices such as hydraulic system overflow valve，Ensure the operation safety of the whole machine。

The working condition is appropriate：

● Series multi-way valve-controlled hydraulic system，All actions can be compounded，And that switch between actions is not decelerate.。

● Optional free hook winch，Meet most of the foundation construction requirements。

● One key can realize the switching of main and auxiliary hook working conditions.，More convenient。

Transportation and disassembly optimization：

● A-frame can be self-cocked without oil cylinder，Achieve rapid assembly。

● The weight of a single counterweight shall not exceed 6.25t，Small auxiliary lifting equipment can complete the assembly of counterweight.
