Main Specification for the QY25K Moible Crane
Main feature
Max. rated lifting capacity: 25T
Max.lifting moment with min. boom lengh: 948.15kN.m
Length of the whole crane: 12.36M
Width of the whole crane: 2.50M
Height of the whole crane: approx. 3.38M
Gross weight: approx. 27.9T
1) QY25K-I truck crane profile and hydraulic system has won 6 China state patens.
2) 4-section boom of all-round octagonal cross-section, single cylinder for front support elevating low center of gravity, good stability
3) Main winch and auxiliary winch separated from each other can work not only individually but also
simultaneously
4) Full-dimension driver's cab with wide vision is convenient for operation
5) Swing system with free-sliding function can automatically align to load. Pinion offset makes meshing clearance easy to adjust
6) New materials are used to minimize the total weight and maximize the whole vehicle performance.
Main performances are in the leading position in the industry
7) Hydraulic pilot control system can finish all operations precisely with gently pushing the two joysticks
on arm-rest. (Mechanical operation system is optional for customers)
8) Hydraulic valve block is integrated modular designed, little pressure loss and high efficiency
9) Balance valve designed with international technology, oil filter, anti-cavitation device and plug hydraulic circuit make operation more reliable
10) Well-equipped safety devices, such as automatic moment limiter, hoist height limiter, and wire rope
over-release cut-out device, make operation safer
11) Engine, air conditioners for superstructure and chassis and hydraulic device are available for option
