Product Description

650t Super Heavy Crawler Crane QUY650 
 

As to the products produced in the same platform, in addition to most of the electrical and hydraulic components, majority of structural parts are also interchangeable, such as a set of fixed jib (including fixed jib pivot section, fixed jib intermediate sections, FA-frame, front tilting-back support of fixed jib, rear tilting-back support of fixed jib, fixed jib front anchoring rods and fixed jib rear anchoring rods), load hook, derricking mechanism, tip boom, rear counterweight base plate and so on, so as to reduce the operating costs of the users.

Series-connected multiple valve-controlled hydraulic system is applied, so that all simultaneous movements can be achieved and no deceleration will occur during the switching of crane movements. Single rope speed on the outmost layer of hoisting winch 1 is 132m/min. To improve lifting efficiency, hoisting winch 1 with free-fall function is available for an option.

A-frame can be erected by itself without the help of oil cylinder, thus achieving rapid assembly of the crane. The weight of
single counterweight plate is less than 6.25t, so that the counterweight can be assembled by use of a small-sized auxiliary crane.
The crawler carriers can be extended and retracted, and the maximum transport width of the crane is 3.12m.
