Consultation phone number:-/, welcome to call us! 1. Purpose The R series thin jack is a detached hydraulic jack, which is smaller in size and can produce greater working capacity. It is especially used in places with narrow space and has the functions of being light, flexible, and with high force. This product is widely applicable It is used in electric power, chemical industry, steel, bridge, machinery and other enterprises, and exerts its infinite power. 2. If a thin jack with a smaller stroke is required, please choose an R ultra-thin jack. If a jack with a large tonnage is required, please choose a large-tonnage electro-hydraulic jack. If a jack with a large tonnage and a large stroke is required, please choose an ultra-high-pressure electro-hydraulic jack. The jack can be customized according to customer requirements. For jacks with special specifications that require customization, the optional hydraulic pump stations are B manual pumps and B series electric pump stations. If several thin jacks are required to lift at the same time, please choose R-type synchronous jacks. If you need to support heavy objects for a long time, please choose automatic Locking jack R thin jack 3. How to use the thin jack (split hydraulic jack). Before use, you must check whether all parts are normal. . When using, the regulations in the main parameters should be strictly followed, and over-height and overloading should be avoided. Otherwise, serious oil leakage will occur at the top of the cylinder when the lifting height or lifting tonnage exceeds the regulations. If the amount of oil in the manual pump body is insufficient, fully filtered hydraulic oil must be added to the pump before it can work. , electric pump please refer to the electric pump instruction manual. 2. The center of gravity of the heavy object should be moderate, the focus point of the jack should be reasonably selected, and the bottom surface should be padded flat. At the same time, the soft and hard conditions of the ground should be taken into consideration, whether it should be lined with tough wood, and whether it should be placed smoothly to avoid sinking or tilting under load. . After the jack lifts the heavy object, the heavy object should be supported firmly with supports in time. It is prohibited to use the jack as a support. If you need to support heavy objects for a long time, please use a self-locking jack. . If several jacks are required to lift at the same time, in addition to placing the jacks correctly, multiple diverter valves should be used, and the load of each jack should be balanced, and attention should be paid to keeping the lifting speed synchronized. It is also necessary to consider the possible sinking of the ground due to uneven weight to prevent the dangerous objects from tilting. . When using, first connect the quick connector of the manual pump to the top, then select the position, tighten the oil drain screw on the oil pump, and then it can work. To lower the piston rod, slightly loosen the handwheel of the manual oil pump in the counterclockwise direction. The oil cylinder will be unloaded and the piston rod will gradually descend. Otherwise, it will be dangerous if the descent speed is too fast. . This jack has a spring return structure. After lifting, it can be quickly taken out, but the connected hose cannot be used to pull the jack. , Because the lifting stroke of the jack is small, users must not exceed the rated stroke when using it to avoid damaging the jack. . Severe vibration of the jack should be avoided during use. , Not suitable for use in workplaces with acids, alkalis, and corrosive gases. Users should check and maintain regularly according to usage conditions. 4. Precautions The thin jack is a separate hydraulic jack, so pay attention to the use of the hydraulic system. . If air-draining occurs during use, you can first loosen the oil drain screw on the pump body, hold the pump body vertically and air-dry it with the head downwards for a few times, then tighten the oil drain screw, and you can continue to use it. . When using, no unbalanced load or overloading is allowed to avoid danger of damage to the jack. Do not remove the quick connector when there is a load to avoid accidents and damage to the machine parts. This machine uses oil as the medium, and the oil and the machine must be well maintained to avoid clogging or oil leakage, which will affect the use effect. For new or long-standing hydraulic jacks, because there is a lot of air in the cylinder, the piston rod may jump slightly when it is started to be used. The hydraulic jack can be reciprocated without load for several times to eliminate the air in the cavity. . For a jack that has been idle for a long time, the seal will harden due to the long-term inactivity of the seal, which will affect the service life of the hydraulic jack. Therefore, when the hydraulic jack is not in use, the hydraulic jack must be reciprocated without load several times a month. , High-pressure oil pipes have been tested by (/) before leaving the factory. However, since the hose is prone to aging, users need to check it frequently, usually six months, and three months for frequent users. Use .(/) to test the pressure during inspection. If there are explosions, bulges, leaks, etc., do not use it. , Technical specifications should be strictly followed during operation, and users should check and maintain regularly according to usage conditions.
