Manufacturer sells electric hydraulic jack RR double acting jack

Description :

　　Product Features:

　　1) The surface is treated with baking paint, which has a bright luster and is not easy to rust.

　　2) The piston is made of high carbon steel material and has undergone hard electroplating treatment to protect the oil ring and extend its service life.

　　3) The joint has a dust cover to protect the screw from impact.

　　4) Mainly used in narrow volume areas, chrome plated plunger, single acting, spring retraction,surfaceBaking paint has the characteristics of light weight, large tonnage, and flexible movement. It has good operational ability in construction sites with small spatial locations. By connecting the high-pressure hose and the thin top, remote operation can be achieved, and the separated structure is very convenient for the maintenance and upkeep of the hydraulic top.

　　Product Specifications

　　Usage:

　　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 and choosejackThe focus must also be on whether the ground is cushioned with tough wood to avoid the risk of tipping during lifting.

　　4jackAfter lifting the heavy object, it should be supported firmly with tough wood in a timely manner. It is forbidden to lift itjackAs a support, it is prohibited to use multiple unitsjackSimultaneously use 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. Loosen the oil drain screw and unload the oil cylinder. Please call to inquire about prices and other details. Thank you!

　　Notes:

　　a) 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 downwards a few times, then tighten the oil drain screw, and continue to use.

　　b) When there is a load, do not remove the quick connector to avoid accidents and damage to the components.

　　c) 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.

　　d) New or long-term oil pressurejackDue to the presence of a large amount of air in the oil cylinder, there may be slight jumps in the piston rod at the beginning of use. The oil pressure can be adjusted accordinglyjackMove back and forth 2-3 times without load to eliminate the air inside the chamber. Long term idlejackDue to the long-term non operation of the seal, it has hardened, which affects the service life of the hydraulic jackjackWhen not in use, the oil pressure should be adjusted monthlyjackPerform 2-3 reciprocating motions without load.
