Q: What is the relationship between the winch and the reel and the reel shaft?: Winch system: get off the oil pump through the center of the rotary joint, and then through the main valve, the first through a gale balance valve, and then drive the hoisting motor, hoisting motor through a spline shaft connected to the reducer (some motor directly connected to

Q: What are the safety procedures for truck cranes?: 2, the construction, in case of heavy rain, heavy snow, fog and more than six winds affecting the construction safety, should stop lifting work, and the arm down to a safe position.

Q: What is the weight of a truck crane?: How many tons of truck crane weight does not matter, this parameter specification will not be marked out, driving with a fixed weight when driving together. Of course, large tonnage activities will be marked with the weight, because it needs to input conditions and then hoisting

Q: What is the principle of car hanging arm?: The first section telescopic arms are driven by the cylinder 1, and the second and third sections are driven by the cylinder 2.

Q: What is the design process for a truck crane?: According to the function, performance, operating environment and other factors, and customers to develop a detailed user requirements manual, and then determine the development goals.

Q: Why the car crane rotation angle can not be more than 45 degrees: Can not put the car crane when the tank with it,

Q: What is the advantage of a car crane?: Mobile cranes are widely used in various fields of lifting equipment, it is to reduce labor intensity, save manpower, reduce construction costs, improve the quality of construction and speed up the construction speed and so plays a very important role.
