QY90K Truck Crane
All performances are in the lead:the length of fully extended main boom is 55m,and grade ability is 40%,higher road possibility.
The capacity mid-extended boom is 5% over the same-class products made by other manufacturers.
Particular "U"-shaped boom and plug-in boom head makes the tension applied to the boom more equilibrant and smooth.
Exclusive telescoping technology prevents occurrence by mis-operation, and therefore operation safety is improved.
Eight patented technologies and optimized operating system conribute to easy and reliable operations of lifting slewing and elevating.
Six specialized processing techniques supply insurance for product quality.

Innovated boom system with inserted sliders,plug-in head of patented technology and world advanced shaped boom cross section makes excellent lifting capacity, safe and reliable lifting operations.

Exclusive telescoping technology prevents occurrence of core pipe bending,oil cylinder bending and boom breaking caused by mis-operation, and therefore operation safety is improved.

Eight patented technologies ensure the smooth movement, high efficiency & economy of lifting, slewing and elevating mechanisms.

New hydraulic motor with larger original torque makes greater safe second-lifting operation.

Load moment limiter with color LCD realizes intelligent trouble diagnostic, and its precision leads in the same-class products in the industry.

Ergonomic design cabs for driver and operator are spacious enough for flexible and convenient operations.

Six specialized processing techniques ensure high quality production.
