What are the advantages of installing the rail-type elevator and cargo elevator? The advantages of civil engineering are easy to install: there is no need for a machine room above the hoistway， and the top floor can be installed more than meters high. The machine room can be set within the radius of meters of the shaft， with an area of only - square meters. The hydraulic elevator is not equipped with a counterweight device to improve the utilization rate of the hoistway area. The load and load of the hydraulic elevator directly act on the foundation pit through the oil cylinder. The strength of the hoistway is low， and the brick structure or brick-concrete structure hoistway is sufficient.
KPindigaThe explanation is mainly from the mechanism of the lifting platform. Now there are many different types of lifting platforms. In order to better use the lifting platform， we have started to develop different lifting platforms for different industries. The electric lifting platform has become the main product of the small lifting platform. It is small in size， light in weight，Products generous in appearance and practical， easy to move， stable and free in lifting， large in carrying capacity and large in plane area， Stability has become the machinery that many customers compete for. Lifting equipment is used in enterprises of all sizes， so the use of lifting platform is necessary.
FqThe design of the hydraulic lifting platform is unreasonable. If the designer has problems with the design dimension and angle when designing the cylinder barrel and piston rod， then there will be problems in the later stage. Therefore， it is necessary to confirm the technical strength of the manufacturer when purchasing the hydraulic lifting platform; What is the noise of the hydraulic lifting platforms cylinder? If the hydraulic lifting platform is not manufactured in strict accordance with the designers design drawings in the process of manufacturing the machine， and the angle of the cylinder is slightly deviated， it will cause the friction between the cylinder barrel and the piston rod，Products resulting in the noise; The quality of the seals of the hydraulic lifting platform will also affect the sound of the cylinder if the seals are used differentlyConstant friction between the seal and the cylinder wall will cause loud noise， and long-term wear may cause oil leakage due to the cylinder scratch. So when purchasing the hydraulic lifting platform，Small residential elevatorsFixed hydraulic lifting platformWhat is the relevant knowledge pay attention to ask the manufacturer what brand and material of seal is used; Some situations of mechanical running-in do not rule out that the above three conditions are normal， but there will still be noise. If there is no problem after troubleshooting， then dont worry. It is just the running-in problem between mechanical parts. If you run more times， the noise will naturally disappear.
: The rust of spiral elevator is caused by the fact that some manufacturers materials are not stainless steel. If the rust is not serious， sandpaper can be used to polish the rust.
It is strictly forbidden to connect the lifting platform motor to the wrong power supply. It must be v or v voltage to do a good job of daily cleaning， and timely clean the dust and debris on the motor.
yThe development history and current situation of scissor-type aerial work platform With the increasingly widespread use of vehicle-mounted aerial work platform in production it has gradually been recognized by various industries and began to be applied in other industries with similar working conditions. With the continuous expansion of the scope of application， some shortcomings are gradually revealed in the process of use in some occasions， such as its huge size is difficult to use in a narrow working space，Scissor lift_ Hydraulic lifting table_ Guide rail lift - scissor lift manufacturer and the high-speed drive function cannot play its role in a narrow space. In addition， if the hydraulic stabilizer configured on the old vehicle-mounted platform fails， the equipment can not continue to be used. These limitations greatly reduce the working efficiency of the equipment. In order to meet market demandThe remote control aerial work platform was launched. Since the birth of this new product， the field of aerial work platforms has grown rapidly. It is also from this beginning that the global aerial work platforms have begun to develop in the direction of serialization. The structure and production process of this self-propelled remote control aerial work platform are relatively simple. A large number of improved aerial work platform products have entered the American market in large quantities. With the popularity of this product， some new contradictions have emerged. In some special occasions， such as gypsum process， lead process， live working and fire rescue， people urgently need a more compact and portable product. Driven by this demand， the scissor-type aerial work platform can move freely in a narrow space， and even can be used on some fragile ground and bearing ground. At present， the demand for scissor-type aerial work platform is increasing， and its proportion in the rental industry has even reached %.
PThe size of oil cylinder shall be reduced as much as possible under the condition that the design requirements are met. The smaller the cylinder size is， the faster the lifting speed is.
PWorkshop costWhen the distribution box is used， the difficulties will be solved. The above is the companys arrangement of the problems that need to be considered during the transportation of the lift. These factors are the factors that need to be considered for each lifting platform. Therefore， we should try our best to be perfect and impeccable for the lift Many operators of the user units have no way to solve the problems that often occur in the lifting platform. They must apply for professional personnel to carry out on-site maintenance. However， due to the restriction of the working environment and time factors of the equipment， the normal maintenance of the equipment failure can not be carried out comprehensively， and only some special measures can be taken to maintain the basic working performance of the equipment.
: Small-scale pneumatic or electric derusting， which uses the principle of friction generated by air compression or electromagnetic effect to polish and remove rust on the rusty surface of the spiral elevator， can be used for the push rod of precision instruments or for enterprises requiring micro-operation of the spiral elevator.
Drain the hydraulic oil of the hydraulic elevator and discard it. For the outdoor guide rail elevator， tighten the connector and take out the oil filter. After cleaning， clean it with compressed air， and then put it back into the oil tank and connect the pipeline.
Customer firstrThe folding boom elevator is mostly driven by hydraulic mode， and the source of power for the hydraulic system is hydraulic oil. Only when the hydraulic oil is sufficient and the oil quality is high can the folding boom elevator provide greater torque output， thus improving the working efficiency. How can we judge whether the newly filled hydraulic oil is sufficient? What is the hydraulic oil quantity standard?
SSafety performance: The lifting structure is made of high-strength manganese steel rectangular tube， and the scissor-type mechanical mechanism is easy to maintain， with strong stability and high bearing capacity. The large lifting height is about meters， and the large load is about tons of goods.
It seems simple to install the bearing for the elevator， but it is also necessary to pay attention to some details as follows: it is difficult to drive them into the shaft pin when installing the bearing excessively. However， sometimes， some people think of using a hammer to hammer the bearing for the convenience of the device， and use brute force when installing the bearing. In fact， directly hitting the bearing with a hammer causes great damage to the bearing， which is the main reason for causing bearing damage and reducing the service life of the bearing. So we must not go too far when installing bearings. Before doing good， put some soft cloth or cardboard on them， and then install them.
zSmall automatic elevatorSmall elevatorRegularly add lubricating oil to maintain the lift: during the use of the lift， the friction between various components is also relatively large due to the heavy load， especially the lift chain and the lift pivot pin. It is necessary to ensure that the appropriate amount of lubricating oil is added before each use to ensure that the operation is flexible and not blocked. If the elevator is running， let alone carry things. For this reason， people invented the elevator which can easily reach the floor they want to go. But if it rains， it will be very troublesomeWhat should be done properly after water?
Talking about the daily maintenance and use of the motor of the hydraulic lifting platform. Overload is strictly prohibited. Overload will increase the burden of the motor and cause the motor to burn out in serious cases.
