Hydraulic system: mainly oil cylinders, self-made external integrated pump stations Japanese NOK seals oil pipelines, gear pumps, solenoid valves, etc. The Japanese NOK seal used in the oil cylinder has good wear resistance which ensures that the oil cylinder series will not leak oil for a long time. The gear pump pumps the oil in the oil tank into the oil circuit and enters the oil cylinder, thereby driving the top of the rod and raising the equipment; The valve is used to adjust the oil output the ascending and descending speed, and contains an emergency descending device to ensure that the guide rail hydraulic lifting platform can descend safely in case of an emergency.Low cost: The cost is much lower than that of the scissor-type mobile lifting platform, so when purchasing a lifting platform, you must consider the scope of use of the lifting platform, the frequency of work, the load and other factors to choose a lifting platform that suits the work requirements .Shanhaiguan,Improper use of oil: Inadequate maintenance of mobile lifts and other high-altitude work platform equipment will cause the fitting clearance of parts to be small,ShanhaiguanGuide rail lifting cargo elevator, and the oil is not easy to form a uniform oil film on the friction surface. In addition, due to assembly and other reasons, it is difficult to ensure the uniformity of the fitting clearance. Thereby reducing the efficiency and causing early abnormal wear of equipment parts; in severe cases, it will cause scratches or bites on the precisely matched friction surfaces resulting in abnormal noise of the equipment.Features of hydraulic lifts: According to the working mode, hydraulic lifting platform products are divided into crank arm hydraulic lifting machines, scissor hydraulic lifting machines, mast type hydraulic lifts, and straight arm hydraulic lifting machines. The hydraulic lift is a replacement product of the folding arm lift (lifting platform) and the scissor lift (lifting platform). It can be widely used in stations, docks, airports, post and telecommunications, municipal gardens, garages, cleaning companies, public building facade decoration, decoration or installation and maintenance of power systems, etc. The lift has the advantages of light weight, self-propelled, electric start, self-supporting legs, simple operation, large working area, especially the ability to cross obstacles for high-altitude operations and the like.Dresden,Guide rail lift (also known as freight elevator) is a non-scissor hydraulic lifting platform, which is mainly used in industrial plants, restaurants, warehouses,ShanhaiguanWarehouse elevator, docks,Shanhaiguan10 meter cargo elevator, workshops and other places that need to move goods vertically between high-rise buildings above the second floor. The low height is especially suitable for sites where the site is not suitable for digging pits. What problems do we need to pay attention to in these places where elevators are used?In addition to the fixed mode, the elevator also has a vehicle-mounted mobile type. As the name implies, and of course it is more useful. For example There is this kind of lifting equipment in the airport, and it is also possible to install this kind of equipment in stations or stadiums. Since it can be moved, the scope of operation is not limited to a certain place, and it can be used wherever lifting operations are required. It can be used. For example, when installing outdoor advertisements, the height of some advertisements is relatively high. At this time, mobile lifting equipment can be used to send billboards or staff to the designated height to work. This kind of equipment can also be divided into two types according to the driving mode: hydraulic lifting and electric lifting. The so-called hydraulic lifting is driven by hydraulic oil to reach a specified height. The electric mode is driven by a motor or geared to lift to A certain height, but at present, hydraulic lifting platforms are more widely used.Knowledge popularization of scissor-type fixed lifting platform Superior performance: equipped with safety devices to prevent overloading of the lifting platform; equipped with protection valves to prevent hydraulic oil pipes from breaking; equipped with emergency descending devices for sudden power failures; Lock safety device.

In addition, during installation, it is strictly forbidden to use hammers, etc. to prevent damage to bearings or gears due to excessive axial force or radial force. Be sure to tighten the mounting bolts before tightening the force bolts. Before installation, clean the anti-rust oil on the motor input shaft, the positioning boss and the connection parts of the elevator with gasoline or zinc and sodium water. Its purpose is to ensure the tightness of the connection and the flexibility of operation, and to prevent unnecessary wear and tear.When the distribution box is used, the leakage switch meets the requirements for construction elevators. If the installed fixed elevator is frequency conversion, the leakage switch should be adapted to the frequency converter when selecting the leakage switch.Test the freight elevator every day to see if the freight elevator can operate normally.How many?,After the goods are transported, clean up the debris on the platform.The motor winding is short-circuited. When a short-circuit fault occurs in the motor winding, the short-circuit current is much larger than the normal operating current, which increases the copper loss of the winding, causing the winding to overheat and even burn out.Test the freight elevator every day to see if the freight elevator can operate normally.

The wrong connection of the motor of the elevator When a coil, coil group or one-phase winding is reversed, it will cause a serious imbalance in the three-phase current and cause the winding to overheat.Inspection requirements,It is strictly forbidden to switch the electric control switch with wet hands. Many people tend to ignore this detail. Although the safety voltage of the hydraulic lifting platform is below V, if you touch the power supply with your hands, it may cause lifting failure in light cases, or electric shock accidents in severe cases.Usually check the connection status of each part, if it is loose, it should be tightened. The tightness of the connecting bolts of the body should be checked when the body is under pressure, and all connecting shafts must have cotter pins and must be fully expanded.The scissor-type fixed lifting platform is a kind of transportation and handling equipment for transporting goods from a certain height to another height. After the operation is completed, does not occupy the ground space, and does not affect the passageway.Shanhaiguan,As for the guide rail elevator installed outdoors, it is often exposed to rain and sunlight, so special attention should be paid to regular maintenance and inspection to avoid accidents.This kind of fixed lifting equipment can also be used in the warehouse. For example, a certain floor in the warehouse needs to be lifted to send goods or personnel into the designated warehouse.Today, the editor will talk about a series of safety devices and their uses on the guide rail hydraulic lifting platform.
