xLuchengThe impact of low temperature environment on hydraulic oil， lubricating grease， and diesel in hydraulic elevators. The lifting leg retraction and retraction system as well as the winch， slewing， and telescopic actions of lifting operations are all transmitted by hydraulic oil as the working medium. The viscosity of hydraulic oil is crucial. If the viscosity is too high， the internal friction resistance of the system increases， the pressure loss increases， the oil temperature rises too fast，Mobile Scissor Lift Platform and the operation lags behind; The viscosity is too low the volumetric efficiency of the pump is low， the lubrication performance is poor， so special attention should be paid when choosing low-temperature hydraulic oil.
The working principle of a guide rail type cargo elevator is basically to use the power unit of the hydraulic station to drive the hydraulic oil to generate pressure， causing the cylinder piston to move back and forth to drive the elevator platform to rise and fall. Therefore， it is important to focus on whether the main components of the hydraulic unit are reliable.
MSokoneWhen conducting high-altitude operations， the materials used must be placed securely. The tools used must be placed in the tool bag with your hands to prevent falling and injuring people.

When setting up scaffolding， the wooden， bamboo， and metal fittings used must be firm， and it is ruled out to reduce the load. Serious bias load，Mobile Scissor Lift Platform ruled out by adjusting the center of gravity. Add gas to the oil circuit， and eliminate the possibility of adding sufficient hydraulic oil. If the oil is dirty，RuthAutomatic aluminum alloy lifting platformBriefly describe daily faults and solutions replace the hydraulic oil to eliminate it.
rTo understand the emergency descent adjustment of the lifting platform， you first need to understand the hydraulic lifting platform combination power unit， which is a micro integrated hydraulic station. Mainly used as a power unit for hydraulic elevators and lifting platforms， it is composed of motors， oil pumps， integrated valve blocks， valve blocks， hydraulic valve blocks，Lifting platform - elevator - hydraulic lifting platform - elevator manufacturer and various hydraulic accessories such as accumulators. Compared with conventional hydraulic stations that meet the same principle requirements， it has advantages such as compact structure， small volume， light weight， high efficiency， reliable performance， beautiful appearance， no leakage， and low price.
WThe working environment of the lifting platform.
LInspection basisThe frequency conversion system circuit of the construction elevator is mainly composed of two parts: the main circuit and the circuit. The main circuit mainly consists of a construction lifting cargo elevator (hereinafter referred to as the lifting cargo elevator) driven by a more complex rectifier. Before installation， and the lifting cage and driving mechanism are installed in the guide rail frame respectively， and the two are connected. Start by adjusting the driving mechanism by electrically driving the suspension cage up to m above the ground or off the ground buffer spring (or support). The adjustment sequence is as follows: . Use a special wrench to rotate the eccentric shaft of the lower double (single) swing wheel to adjust the eccentricity to keep the installation surface of the mechanism perpendicular to the horizontal plane， and make the upper and lower swing wheels evenly contact the guide rail at the same time. Rotate each wheel body by hand to check if it evenly presses the guide rail; . Use a special wrench to rotate the eccentric shaft of the gear rack back pressure wheel to adjust the side clearance during gear rack meshing. When adjusting， use a feeler gauge to measure the side clearance to .; Between .mm， each pressing wheel should evenly press on the back of the rack. Move each wheel body by hand to check if it evenly presses against the tooth back. Similarly， adjust the guide rollers on both sides of the guide rail. The adjustment key is to adjust the guide wheel on one side of the guide rail to lightly press it onto the guide rail. When moving the wheel body by hand， it should be possible to rotate but there should be obvious obstruction; The roller on the other side should maintain a clearance of .-. ram with the guide rail; . Adjust the lifting cage according to the above and sequence. If the driving mechanism and the lifting cage are integrated into the lifting cargo elevator， the lifting cage should be adjusted according to the and sequence of adjusting the driving mechanism. Conduct a visual inspection of the contact and operation of each roller， and use the lead pressing method and coloring method to check the meshing condition of the gear pair; Fine tune pairs of unsatisfactory parts. The key point is to carefully adjust the meshing status of the gear pair: when the contact spot shown in appears on the contact surface of the gear rack it indicates that the driving mechanism is tilted towards the side of the guide rail. At this time， the lower swing wheel (single or double wheel) should be adjusted to move the lower part of the driving mechanism towards the direction of the guide rail until the area of the contact spot reaches more than % of the contact surface of the gear rack. The smaller the contact area， the easier it is to damage the gears and racks.
aEPoor quality hydraulic oil is as transparent as good hydraulic oil at room temperature， it will appear black， white wax， and solid blocks will also appear.
Check all safety devices， including buzzers， travel switches， sensors， etc.， for normal operation and accurate signals.
Adjust and correct various safety doors and mechanical interlocking equipment
knowledgegRegularly check the connection of each part and tighten it if there is any looseness. The tightness of the body connecting bolts should be checked when the body is under pressure (the rotating arm can be used to cause compression)
ZDifferent grades of hydraulic oil cannot be mixed to prevent chemical reactions and changes in performance of the hydraulic oil. Dark brown， milky white， and odorous hydraulic oil are spoiled oils and cannot be used. The prevention of solid impurities from entering the hydraulic system of large tonnage lifting cargo elevators is the life of the hydraulic system. Clean hydraulic oil is the key to the hydraulic system. There are many precision components in the hydraulic system， some with damping holes and some with gaps. If solid impurities invade， it will cause precise components to be pulled， jammed， and oil passages to be blocked， endangering the safe operation of the hydraulic system. The general ways for solid impurities to invade hydraulic systems include: unclean hydraulic oil; Refueling tools are not clean; Careless refueling， repair， and maintenance; Hydraulic components peeling， etc. Solid impurities can be prevented from entering the system from the following aspects: hydraulic oil must be filtered and filled during refueling， and refueling tools should be reliable and clean. Do not remove the filter at the fuel tank filler in order to increase refueling speed. Refueling personnel should use clean gloves and work clothes to prevent solid and fiber impurities from falling into the oil.
The fourth hydraulic elevator is not equipped with a counterweight device to improve the utilization rate of the shaft area， and the lift car can be larger. The fifth lifting stage can provide an integrated steel structure hoistway with years of experience in China， with high-quality double-sided sandwich color steel plates for external sealing. Users only need to provide a pit and installation space to enjoy convenience and speed，Safely integrated hydraulic elevators and related services.
tLuchengAttention: Abnormal meshing of gear teeth should be avoided: uneven contact of rollers should be avoided; Avoid diagonal contact between the guide rollers; Avoid prolonged simultaneous contact of the guide rollers; The above abnormal phenomena can lead to rapid wear and even scrapping of gears， racks， rollers， and guide rails. If adjusted more carefully， it will be more beneficial for the service life of the elevator.
wMProtective neutral devices should be installed on the shells of welding and cutting equipment， electrical boxes， etc.
The size of the oil cylinder should be minimized as much as possible while meeting the design requirements. The smaller the size of the oil cylinder， the faster the lifting speed.
