Secondly， lets take a look at how to choose a hydraulic lifting platform. When purchasing a hydraulic lifting platform， an enterprise must first comprehensively consider the companys use range， utilization rate， rated lifting capacity and other factors， and choose a hydraulic lifting platform that is suitable for the unit. Ask for a working grade lift. Carry out market research according to the proposed technical parameters. The first condition for choosing a supplier is the reputation of the manufacturer，Domestic elevator and then the after-sales service capability.
1The hydraulic freight elevator manufacturer reminds that the electric hoist freight elevator completes the lifting of the freight elevator through the pulling of several steel wire ropes. This kind of freight elevator often causes the platform of the lifting freight elevator to be skewed due to the tightness of the steel wire ropes，GuizhouGuide rail hydraulic lifting platformResearch on Selection and Assembly Technology of and the stability and safety are poor. Limited， it can only be used for the transportation of small tonnage goods， so the wire rope freight elevator is increasingly replaced by the hydraulic guide rail type elevator.
gHamburg AmesbourtIn addition， whether the layout is convenient is also a very important issue. For example， on larger or higher waves， there are layout issues with jacking mechanisms. At this time， the lifting structure should be selected to determine the installation position of the oil shoulder， because the lifting point of the bridge is not in a straight line during the lifting process. Therefore， the cylinder will swing during the lifting process，Domestic elevator so the connection between the two ends of the cylinder and other components must be the same hinge. In addition， whether the installation of the hydraulic freight elevator cylinder is the tail lug type the middle pin shaft type or the head pin shaft type must also be determined after comparison and calculation. The main advantage is that the effective area of the cylinder is large and the installation height of the whole machine is low. The disadvantage is that if the cylinder stroke is large， the cylinder has stability problems， and then the cylinder layout is difficult. The main advantage of the lifting mechanism of the hydraulic freight elevator is that there is no stable transmission of the height of the installation frame. Therefore， this form can be considered in places with large drop objects. The head oil type can reduce the installation height， but if it is larger， and the greater the lifting height， the faster the force will be， the head pin type is not suitable. In order to comprehensively consider the height of the installation frame and the force of the oil cylinder during the lifting process， an intermediate installation method can be considered and the installation position can be set at an appropriate height according to the calculation.
Pre-install the equipment，Domestic elevator keep the access road clear before pre-installation， and have enough parking space. Some hydraulic freight elevators require crane-assisted installation，GuizhouGuide rail hydraulic lifting platformResearch on Selection and Assembly Technology of some require equipment such as forklifts to be installed， and some can be pre-installed manually. When truck cranes and forklifts are required for auxiliary installation， full consideration should be given to whether the site environment meets the working conditions of truck cranes.
ZRomaniaBefore work， carefully check all parts of the mobile lifting platform， focusing on checking whether the screw connection is reliable whether there is leakage of hydraulic pipeline components， and whether the wire contacts are loose or damaged.
SzThe hydraulic elevator is not equipped with a counterweight device， which improves the utilization rate of the hoistway area.
The hydraulic freight elevator manufacturer reminds the basic principle of the speed regulation circuit of the hydraulic freight elevator. The system often needs to adjust the movement speed of the hydraulic cylinder and the hydraulic motor to meet the working cycle needs of the main engine. The speed of hydraulic cylinders and hydraulic motors depends on displacement and input flow. It can be seen that by changing the flow or displacement， the speed of the cylinder and motor can be adjusted.
The elevator itself has a simple structure and is easy to maintain，Elevator Price_ Hydraulic ladder_ Household elevator_ Household elevator - elevator manufacturer which has won the favor of the majority of enterprises and individual customers. The hydraulic lift is a multifunctional lifting and unloading mechanical equipment. The hydraulic lift lifting system is driven by hydraulic pressure， also known as hydraulic drive lift.
dThe hydraulic system of the hydraulic lifting freight elevator is equipped with anti-falling and overloading safety protection devices， and operation buttons can be set on each floor and lifting platform to realize multiple points. The product has a solid structure， large load capacity， stable lifting， easy installation and maintenance， economical and practical， there should be a device for emergency lowering of the workbench.
Wsuperior qualityFor the hydraulic cylinder in the hydraulic lift， it is unrealistic to adjust the speed by changing its effective area A (equivalent to the displacement). Generally， the speed can only be adjusted by changing the flow rate. For variable variable motors， speed regulation can change both the flow rate and the motor displacement.
eSAdvantages of civil construction: there is no machine room above the hoistway， and the top floor height can be installed above meters; the machine room can be set within the radius of meters of the hoistway， and the floor area is only - square meters; the hydraulic elevator does not have a counterweight device， which improves the utilization of the hoistway area rate; the load and load of the hydraulic elevator act directly on the foundation pit through the oil cylinder， the strength of the hoistway is low， and the brick structure or brick-concrete structure is sufficient.
When moving or towing the hydraulic platform， the supporting legs should be retracted and the platform should be lowered to a low position. It is strictly forbidden for operators to move the platform when it is in a high position.
During the maintenance of the rail-type hydraulic lifting platform， dismantle the fuel tank cover， filter cover， detection hole， hydraulic oil pipe and other parts of the hydraulic oil tank. When the oil passage of the system is exposed， dust should be avoided. The disassembly part must be cleaned thoroughly before opening. For example， when removing the fuel cap of the hydraulic oil tank， first remove the soil around the fuel tank cap， loosen the fuel tank cap， and remove the sundries remaining in the joint (do not wash with water to prevent water from seeping into the fuel tank)， and open the fuel tank cap after confirming that it is clean. If you need to use a wiping material and a hammer you should choose a wiping material that does not remove fiber impurities and a special hammer with rubber attached to the striking surface. Hydraulic components and hydraulic hoses should be carefully cleaned and assembled after drying with high-pressure air. Choose a well-packed filter element (the inner packaging is damaged， although the filter element is in good condition， it may not be clean). When changing the oil， use the wiping material to carefully clean the dirt at the bottom of the filter housing.
Highly recommendedfThe elevator itself has a simple structure and is easy to maintain， which has won the favor of the majority of enterprises and individual customers. The hydraulic lift is a multifunctional lifting and unloading mechanical equipment. The hydraulic lift lifting system is driven by hydraulic pressure， also known as hydraulic drive lift.
XThe basic applications of hydraulic freight elevators are divided into mobile hydraulic freight elevators， fixed hydraulic freight elevators， guide rail freight elevators， etc. It has good mechanical properties and makes the elevator more stable. high stability. Hydraulic freight elevators are also used in stations， docks， public buildings and other industries and fields that require work at heights. They require different styles for different occasions. Some require guide rail hydraulic freight elevators， some require fixed， but most use mobile hydraulic freight elevators. When using it， we must pay attention to this， especially when purchasing a hydraulic freight elevator， we must compare it with our own construction industry to see which hydraulic freight elevator is suitable for our use.
The contact surface of each brush should be kept clean， and the pressure of the brush should be adjusted so that the contact area is not less than %.

. Elevator relief valve noise The pilot valve front chamber of the relief valve has air in the front chamber of the relief valve. The damping hole on the main valve core of the relief valve is blocked by oil and dirt. If the viscosity of the large hydraulic oil is too low or too high， it will resonate with the components in the circuit. Eliminate: strengthen the seal， repeatedly adjust the pressure by raising and lowering the pressure several times， exhaust and clean the valve body， so that the damping hole can be unobstructed. The pressure setting of other hydraulic components cannot be close to the pressure setting value of the relief valve. . Elevator pipeline noise Pipeline noise is usually caused by too many dead bends in the hydraulic pipeline or loose fixed ferrules.
