Application and Development of Pneumatic Jack

Choose a suitable tonnage pneumatic jack for the job, and carry it with a weight center greater than 1.2 times in order to prevent people from choosing a pneumatic jack; The appropriate minimum air pressure jack is removed for the convenience of minimizing height. The air pressure jack is used to support the height of the heavy object under the force of the cushion sleeper's ups and downs in the gap. The lifting height of the air pressure jack is greater than the thickness of the sleeper and the deformation of the sleeper.

When using multiple pneumatic jacks to lift the same equipment, the same type of pneumatic jack should be used, and the rated lifting capacity of each pneumatic jack should not be less than 1.5 times. We provide the equipment's gravity. After wiping clean, use a pneumatic jack to check whether each component may be sensitive, with or without damage, to avoid quick coupling load shedding and prevent accidents and damage to the components. When using a pneumatic jack, it should be placed flat and not tilted. The bottom pad should be placed to prevent the foundation from sinking or the load from transferring away. The pneumatic jack should be tilted or overturned, and a sturdy bottom pillow or steel plate should be placed to expand the pressure bearing area to prevent falls or slide events; Do not use wooden or steel oil spill covers to avoid slipping force attacks and accidents; The position of the top weight must be safe and the solid part of the equipment must be resistant to damage.

Weightlifting objects are only weighted at one end with a pneumatic jack placed on the axis of symmetry, taking into account the difference in the flow direction of long and heavy objects and the direction of the pneumatic jack (the base of the pneumatic jack). If two air pressure jacks are used at one end of the weight, the direction of the base should be slightly eight symmetrically placed on both sides of the axis of symmetry. Two or more air pressure jacks should be used for lifting operations under unified command and coordination. The air pressure jacks should be placed in a boring, central dust-free storage area, not suitable for using corrosive gases in pH environments, and should not be placed outdoors in sunlight or rain. Pneumatic jack is a type of jack that uses a plunger or pneumatic cylinder as a rigid lifting component. Simple lifting equipment generally only has a lifting mechanism for lifting heavy objects. Simple construction, light weight, easy to carry, and convenient to move. The manufacturer of pneumatic jacks pointed out that pneumatic jacks can be used horizontally or upside down. Because the structure of the pneumatic jack is different from that of a typical upright jack, the power source of the pneumatic jack, which is the manual or electric oil pump we separate from the cylinder body, is connected by a rubber hose woven with steel wire in the middle. This way, whether the pneumatic jack is used horizontally or upside down, the pneumatic cylinder can enter the cylinder body without causing the hydraulic oil level to decrease or shift due to being integrated with the cylinder body, making the jack unusable.

When using a pneumatic jack for lifting operations, a suitable tonnage of pneumatic jack should be selected, and the load-bearing capacity should not exceed the limit. The load-bearing capacity of the selected pneumatic jack should be greater than 1.2 times the weight of the heavy object; The minimum height of the air pressure jack is appropriate. In order to facilitate removal, the minimum height of the air pressure jack should be suitable for the clearance at the bottom of the heavy object where force is applied. During the lifting process, when using sleepers to support the heavy object, the lifting height of the air pressure jack should be greater than the sum of the thickness and deformation of the sleepers. If multiple pneumatic jacks are used to lift the same equipment, the same model of pneumatic jack should be selected, and the sum of the rated weights of each pneumatic jack should not be less than 1.5 times the weight of the equipment it supports. During the process of lifting the weight from the bottom of the cushion frame with a pneumatic jack, in order to prevent the pneumatic jack from tilting or causing the piston to suddenly fall and cause accidents, the distance between the cushion and the heavy object should not exceed the thickness of the cushion. The lifting height of the weight must exceed the rated weight of the pneumatic jack's lifting height. Place sleepers under the pressure jack and lower the lifting bottom repeatedly until the required lifting height is reached. Under the heavy pressure of support, it is necessary to increase the support area for a long time to ensure that the pneumatic jack is not damaged.
