Product name: Ultra-thin hydraulic jack
Product introduction: The ultra-thin hydraulic jack mainly has RSM series, and the tonnage is particularly complete. It has the characteristics of light weight, large tonnage and flexible movement. The mounting holes make it easy to fix, and the painted surface makes it more resistant to corrosion. RSM type ultra-thin hydraulic jack, chrome-plated plunger, single-acting, spring retraction, no saddle on the grooved plunger surface, RSM-750, RSM-1000, RSM-1500 is equipped with a portable handle, mainly for narrow volume In a small construction site, it has a good operational ability. The volume is smaller than the RCS thin top, and the high-pressure hose is connected to the thin top to achieve long-distance operation. The separated structure is convenient for the maintenance and maintenance of the hydraulic top.
Product details of ultra-thin hydraulic jack
First, the use of ultra-thin hydraulic jack
1. Before use, you must check whether each part is normal.
2. The center of gravity of the heavy object should be selected properly, the jacking point of the jack should be selected reasonably, and the bottom surface should be leveled. At the same time, the soft and hard conditions of the ground should be considered, and the tough wood should be lined up.
3. After the jack lifts the weight, it should be supported by the support in time. It is forbidden to use the jack as a support. If you need to support heavy objects for a long time, please choose CLL self-locking jack
4. When several jacks are required to lift at the same time, in addition to correctly placing the jacks, a multi-top diverter valve should be used, and the load of each jack should be balanced. Pay attention to keep the lifting speed synchronized. It is also necessary to consider the situation where the ground may sink due to uneven weight to prevent the tilt of the weighted object from causing danger.
5. When using, please strictly abide by the provisions in the main parameters, and avoid excessively high overload. Otherwise, when the lifting height or lifting tonnage exceeds the regulations, serious oil leakage will occur at the top of the cylinder.
6. When in use, first connect the quick connector of the manual pump to the top, then select the position, and tighten the drain screw on the oil pump to work. To lower the piston rod, loosen the handwheel of the manual oil pump slightly in the counterclockwise direction, unload the cylinder, and the piston rod will gradually descend. Otherwise, the descending speed will be dangerous.
Second, the maintenance of ultra-thin hydraulic jack
1. If there is runaway phenomenon during use, first loosen the oil drain screw on the pump body, lift the pump body upright and hit it downwards a few times, and then tighten the oil drain screw to continue using.
2. Don't add eccentric load or overload when using to avoid the danger of jack damage. When there is a load, do not remove the quick connector to avoid accidents and damage to the parts.
3. This machine uses oil as the medium. It is necessary to do well the maintenance work of the oil and this machine to avoid blockage or oil leakage, which will affect the use effect.
4. For new or long-time hydraulic jacks, because there is more air in the cylinder, the piston rod may have a slight jump phenomenon when it is used. You can reciprocate the hydraulic jacks 2-3 times under no load to eliminate Air in the cavity. For long-term idle jacks, the seals harden due to long-term non-operation of the seals, which affects the service life of the hydraulic jacks. When the hydraulic jacks are not in use, the hydraulic jacks are reciprocated 2-3 times a month without load. .
5. The high pressure oil pipe has passed the 105Mpa (1050Kgf / cm2) test when it leaves the factory. However, because the hose is easy to age, users need to check it frequently, usually for six months, and frequently for three months. Use 87.5Mpa (875Kgf / cm2) to test the pressure during the inspection. It cannot be used if it is burst, bulged or leaked.
6. The jack is a spring return structure. After lifting, it can be quickly removed, but the connected hose cannot be used to pull the jack.
7. Because the lifting stroke of the jack is small, users should never exceed the rated stroke when using it to avoid damaging the jack.
8. Avoid severe vibration of the jack during use.
9, not suitable for use in the workplace with acid and alkali, corrosive gases.
10.The user should check and maintain regularly according to the use situation
11. The technical specifications should be strictly adhered to during operation, and the user should regularly check and maintain according to the use situation.
