Note 1: due to the use of construction machinery is more harsh environment, therefore, the sealing requirements of the gas spring is higher, should avoid the use of dust and other debris into the gas spring. In addition, to prevent sharp tools to scratch or destroy the surface of the gas spring piston rod, and do not paint the piston rod and corrosive chemicals.

Note two: gas spring stroke should be on the basis of the work of a certain margin (10mm), to avoid errors due to the installation process, affecting the life and performance of the gas spring.

Note three: configuration in the construction machinery of the gas spring, due to the use of the environment for the outdoors, the service life is generally shorter, the design should be considered.

Note four: air spring working environment temperature range is generally -35 ~ +60 C.

Note five: gas spring in the course of work can not withstand lateral force or oblique force, otherwise there will be partial wear phenomenon, leading to early failure of the gas spring, the design should also be considered.

Note six: for door structure lighter and no locking device, designed to ensure the door closed, gas spring fixed support and a movable support point through the rotation center, to ensure that the gas spring can secure the door or the gas spring often pushed open the door to door structure; the heavier (machine cover), best equipped with locking device.

Note seven: the gas spring is closed and the working state can not have a relative movement, its continuous expansion to be controlled within the scope of requirements.

Note eight: the door structure of construction machinery (such as the cover of the machine) is generally heavier, the use of gas springs, should be considered with the selection of the gas spring of the device, in order to avoid the failure of the gas spring caused by security risks.

Note nine: the gas spring should not be used as a limit device, the need to increase the limit device, the general use of rubber head limit
