JRSM ultra-thin jack

JRSM ultra-thin jack

1、 Purpose:
The JRSM series hydraulic jack is a split type hydraulic jack with a smaller volume and greater working capacity, especially used in narrow spatial locations. It has the functions of lightweight, flexibility, and strong pushing force. This product is widely used in enterprises such as power, chemical, steel, bridge, machinery, etc.
1. When the oil level of the pump body is insufficient, it is necessary to add working oil (10 # engine oil) to the pump before it can work.
2. Estimate the lifting capacity and avoid overloading during use.
3. Determine the center of gravity of the lifting object, select the point of force for the jack, and also consider whether the ground is soft or hard and whether it is padded with tough wood to avoid
There is a risk of tipping during lifting.
4. After the jack lifts the heavy object, it should be supported firmly with tough wood in a timely manner. It is forbidden to use the jack as a support, and it is forbidden to count
Use both hydraulic jacks simultaneously to avoid the risk of tipping due to uneven load.
5. When using, first connect the quick connector of the manual pump to the top, then select the position and tighten the oil drain screw on the oil pump to start working. Translate into English
Loosen the oil drain screw and unload the oil cylinder.

2、 Basic parameters of ultra-thin hydraulic jack (split hydraulic jack):

The parameters in the table may change due to improvements without prior notice.
1. If you need several ultra-thin jacks to lift at the same time, please choose JRSM thin synchronous jacks
3、 Usage method
Ultra thin hydraulic jacks are split hydraulic jacks, so when using them, attention should be paid to the use of hydraulic components.
1. Before use, it is necessary to check if all parts are functioning properly.
2. When using, the provisions in the main parameters should be strictly followed, and overloading should be avoided, otherwise the lifting height or lifting tonnage will be affected
When exceeding the regulations, serious oil leakage will occur at the top of the oil cylinder.
3. When the oil volume of the manual pump body is insufficient, it is necessary to first add N33 # hydraulic oil that has been thoroughly filtered to the pump before it can work
Make it.
4. Please refer to the user manual for the electric pump.
5. The center of gravity of heavy objects should be chosen appropriately, and the force point of the jack should be selected reasonably. The bottom surface should be leveled, and the ground should also be considered
Soft and hard conditions, whether to pad with tough wood, whether to place it steadily to avoid sinking or tilting under load.
6. After the jack lifts the heavy object, it should be firmly supported with a support in a timely manner. It is forbidden to use the jack as a support
use If you need to support heavy objects for a long time, please use CLL self-locking jack
7. When multiple jacks are needed to lift at the same time, in addition to correctly placing the jacks, multiple diversion valves should be used, and each one
The load of the jack should be balanced, and attention should be paid to maintaining synchronous lifting speed. We must also consider the possibility of the ground sinking due to uneven weight
To prevent dangerous situations caused by tilting of the lifted object.

8. When using, first connect the quick connector of the manual pump to the top, then select the position and tighten the oil drain screw on the oil pump to start working. To lower the piston rod, manually
The oil pump handwheel is slightly loosened in the counterclockwise direction, the oil cylinder is unloaded, and the piston rod gradually descends. Otherwise, if the descent speed is too fast, it will pose a danger.
9. This jack is a spring reset structure that can be quickly removed after lifting, but cannot be pulled by a connected hose.
10. Due to the small lifting stroke of the jack, users must not exceed the rated stroke when using it to avoid damaging the jack.
11. Avoid severe vibration of the jack during use.
12. Not suitable for use in workplaces with acidic, alkaline, and corrosive gases.
13. Users should regularly check and maintain according to their usage
4、 Precautions for ultra-thin hydraulic jack (split hydraulic jack)
1. If there is a phenomenon of empty tapping during use, you can first loosen the oil drain screw on the pump body, lift the pump body vertically and tap it downwards a few times, then tighten the oil drain screw to continue
use
2. When using, do not add unbalanced or overloaded loads to avoid dangerous damage to the jack. When there is a load, do not remove the quick connector to avoid accidents and damage to the components.
3. This machine uses oil as the medium, and it is necessary to maintain the oil and this equipment properly to avoid clogging or oil leakage, which may affect the effectiveness of use.
4. New or long-term hydraulic jacks, due to the presence of a large amount of air in the cylinder, may experience slight jumps in the piston rod when they are first used. The hydraulic jack can be unloaded
Move back and forth 2-3 times to eliminate the air inside the chamber. Long term idle jacks, due to the long-term non operation of seals, cause hardening of seals, thereby affecting hydraulic jacks
The service life of the hydraulic jack is limited, so when not in use, the hydraulic jack should be moved back and forth 2-3 times a month without load.
5. The high-pressure oil pipe undergoes a 105Mpa (1050Kgf/cm2) test before leaving the factory. However, due to the easy aging of rubber hoses, users need to regularly check them, usually for six months, and use them frequently
The duration is three months. During inspection, use 87.5Mpa (875Kgf/cm2) for pressure testing. If there are any phenomena such as blasting, protrusion, leakage, etc., it cannot be used.
6. During operation, technical specifications should be strictly followed, and users should regularly inspect and maintain according to their usage.
