Huai'an truck crane is a kind of truck crane, which belongs to tire crane. There are many models of this crane, which can have different weights for lifting Equipment displacement In terms of engineering, truck crane is a good choice. This machine is suitable for a variety of lifting environments.
In the construction of truck crane hoisting, because many materials can not be accurately calculated by the computer the center position of the object, when the suspension point is not clear, once tilt or overturn and other conditions, the object will not be damaged and will sink. Therefore, in this case, the construction personnel should rely on their own construction experience to select the key points, do a good job in trial lifting, and carry out normal construction treatment on the basis of ensuring stability. How to select the lifting points of square materials? For the lifting construction of such materials, the selection of lifting points should be more than one, but four. The four lifting points should be located at the symmetrical positions on the four sides of a surface. In order to have better stability and balance at noon, the center of the lifting point and the falling point should be on the vertical line. Attention should be paid to Dalian hoisting. In order to ensure the success of hoisting, the test crane should also be used first.
When lifting, the ground must be solid and smooth, and the ground cannot sink during operation. If the ground is soft, a solid block should be placed under your feet. The horizontal outrigger shall be fully extended, and the front and rear columns can work after leveling the crane. When you extend the outriggers, you need to extend the horizontal legs first, then the vertical legs. When the legs retract, the vertical legs must retract and the horizontal legs retract. After the outrigger operation is completed, all control levers will return to the middle position. Under the load, the working radius will increase due to the deflection of the main boom. This factor should be taken into account when determining the rated total lift mass. Pay attention to check the temperature of hydraulic oil. If the oil temperature exceeds 80 ℃, the seal will be damaged if it is not cooled in time, making the system unable to work. For example, when the hydraulic oil temperature is high and the oil temperature drops for a period of time, the boom will naturally retract. At this time, the arm should be operated to restore the required length.
The inspection of truck crane shall be organized by the equipment safety management department and carried out jointly with the relevant personnel of the user department. In addition to the weekly inspection, the status of the power system, lifting mechanism, rotating mechanism, operating mechanism and hydraulic system of Henan lifting machinery is mainly inspected, and the wear, deformation, cracking, corrosion and other parts are rechecked. ACED, electrical control system operation. Check whether the feeding device, controller, overload protection and safety protection device are reliable. Through test and operation, the fault signs caused by leakage, pressure, temperature, vibration and noise of crane equipment are checked. Understand the technical condition of the crane by observing the detection of the structure, support and transmission components of the crane under the subjective state, and check and determine the abnormal phenomenon of the fault source.
Although the truck crane has become the focus of many friends' consideration and choice, regularity is the focus that every user needs to start thinking about. The signing of the lease contract is the basis for ensuring the effective performance of the rights and obligations of both parties. Therefore, in the general leasing stage, the use of this rationalization is the center of recommendation. With the development of science and technology, cranes are constantly updated and their functions are constantly improved. If enterprises choose to purchase cranes, the equipment will be eliminated from the market within a few years. However, if the crane is leased, this problem can be avoided. During the lease term, we can sign a lease term, and the crane leasing company can choose a new model after the expiration, so the enterprise is equivalent to "buying" a new equipment.
