If the crane is lifting Equipment displacement If the speed is too fast or too heavy, it is easy to tilt or even roll over, so it should be controlled at any time during operation crane Stability. crane During the lifting process, due to excessive weight, excessive inertia force caused by improper operation, sinking of bearing surface or excessive wind force, the crane often loses stability suddenly, or even overturns, causing serious damage.
No matter whether the outrigger is used or not, large moving overturning crane The most dangerous instability state is that the boom is in a position perpendicular to the body roll line. Therefore, in consideration of crane The stability and inlet and outlet stability tests are based on the working status of the right boom. under these circumstances, crane Must have minimum stability. tyre crane And cars crane Whether the machine can be brought back to life depends not only on the stability of the whole machine.
use crane When lubricating oil is used, it can reduce crane The friction of each component, the liquid lubricant for protecting machinery and processing parts, is mainly used for lubrication, cooling, rust prevention, cleaning, sealing and buffering. Huai'an crane rental During operation, the quality of lubricating oil is highly required. Generally speaking, we need to have good thermal oxidation resistance, good stability, less coking and carbon deposition, softness (preferably produced from naphthenic crude oil), good rust resistance and 40 ° C viscosity.
For lubricating oil with better anti-wear performance. It is often used when we work in a leaky environment. For our lubricants, there are not only many varieties, but also good rust resistance, water resistance, cold resistance and heat resistance. The lubricating oil has good antirust performance; Some machines work in the environment with corrosive gas or dust, and the lubricating oil is required to have anti-corrosion performance.
Huai'an Crane Rental Since most construction machinery works in the open air and is easily attacked by rain or moisture, it is required that the lubricating oil has good demulsibility and water resistance and should not react with water, such as water decomposition. Therefore, protect or limit the boom crane The maximum elevation of is very important. There are many methods, such as installing an angle indicator and limiter on the boom, installing an encoder on the luffing mechanism, etc., to prevent the boom from exceeding the maximum elevation and ensure that crane Security.
