Q:What is the difference between the performance of a truck crane and a crawler crane?
The operation on the crane is the same as the operation of the boom to complete the boom of the ups and downs, stretching, rotation and hook and hook.
Q:What is the difference between the main arm and the basic arm of a truck crane?
The secondary arm is for distinguishing from the main arm, and the auxiliary arm includes the first section of the auxiliary arm and the second section of the secondary arm (if there is a second section of the auxiliary arm).
Q:What does the meaning of the letter in the car crane (car crane)?
QUY50 crawler crane is a hydraulic drive, full swing, trussed arm crawler crane, is the first to lead the proportion of technology used in crawler cranes products. The machine is simple, flexible, the whole machine running smoothly, the maximum weight of 50 tons,
Q:What is the reason for the jitter of the crane boom
Exclusion method: the balance valve disintegration cleaning, dredge damping holes.
Q:What are the shortcomings of a car crane?
Crawler cranes get off without cabs, driving operations and lifting operations concentrated in the car control room
Q:What is the difference between a crane and a crane?
Cranes are specially used for hoisting machinery, hoisting machines with cranes (also using hoisting chains), bridges and gantry cranes for industrial production. There are also mobile cranes, floating cranes, crawler cranes
Q:Is a car crane a car crane?
A truck crane is a crane mounted on an ordinary car chassis or a special car chassis, and the traveling cab is provided separately from the hoisting chamber.
Q:What is the characteristic of a car crane?
2. Power, fuel consumption is small, noise in line with national standards;
Q:What is the development process of a car crane?
And China in the small tonnage of the performance of the car crane has been intact, to meet the requirements of real production.
Q:Why does the crane have two cabs?
Behind the control room is used to manipulate the lifting objects up and down, left and right, before and after the other functions.
