Use 1, such as the fuel pump is insufficient, the need to first join the working oil pump (10 # oil) to work. 2, estimated from the weight, avoid overloading use. 3, to determine the focus of lifting objects, select the jack focal point, and must take into account whether the hardness of the ground pad to tough wood, in order to avoid the risk of dumping of produce when lifting. 4, Jack the heavy lifting, the weight should be promptly support firmly prohibit the jack used as support with tough wood. Kou L / YZL / CLL series self-locking jack (self-locking nut jack): large diameter chrome rod design, different from the ordinary CLL self-locking jack, small tonnage self-locking top innerspring, large tonnage jack rely on large self-locking weight piston rod can easily return to overcome the general self-locking jack (single-acting, load retraction) is difficult to back down the problem, limiting travel and overflow function has a protective effect jack is mainly used to support heavy loads will take time occasions (such as major bridges after lifting time required support), to remove the oil pressure reliable long nut to support weight, safe and reliable. Can also be used for a long time underwater, install safety and packing equipment, built-in pressure relief valve to effectively prevent overload, chrome with more corrosion resistance, the piston rod friction smaller, can withstand partial load carrying tonnage negative Heda 5-6% 1, can also select optional installation of hydraulic lock (holding pressure valve) F / YZF electric hydraulic jack to support weight, the advantages of having a controlled return. 2, the electric pump is be selected according to the self-locking jack lifting speed requirements, please see the corresponding pumping concrete B / YZB electric pump.
