The oil cylinder and sealing components are made of imported components to solve the problem of unstable oil pressure and oil leakage of components for customers.Buffer. In order to increase the energy for the car to hit the top or sink to the bottom. Remove rubber or sponge from the buffer and cabin to increase their impact energy; Rope groove slipping and other accidents caused the car to suddenly fall, resulting in a safety clamp. To prevent breakage of the lifting wire rope. A safety clamp that can simultaneously cut off the power supply and stop the car from falling should be removed from the car. A car without safety tongs is not allowed to ride or carry people. If it is a simple electric elevator, there should be a safety device (such as a safety stop pin) to prevent people from suddenly falling when loading and unloading goods in the car; Electric elevators with three or more floors (including three floors) for passengers or passengers.Maastricht,The usual operation of landing and docking.Principle of electric elevator rotary valve: When the electric elevator rises, the rotary valve will automatically open. To close the plug valve, it is necessary to first turn the handle to turn the plug to a degree position until it is closed, and then turn the transmission handwheel to lower the plug and achieve sealing.Berovo,When the wall bracket cannot meet the requirements of the construction site, it should be designed and calculated separately.Setting requirements: For construction electric elevators that operate in multiple shifts, the handover system should be implemented,MaastrichtThree meter electric elevator, and drivers should fill out the handover record form according to the standard requirements. The driver should conduct a pre shift inspection and confirm that there are no errors before starting the machine for operation.The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve, and the return oil from the lower end of the hydraulic cylinder returns to the oil tank through the balance valve, hydraulic control one-way valve, throttle valve, and explosion-proof electromagnetic directional valve. To ensure a smooth descent of heavy objects and safe and reliable braking, a balance valve is installed on the return oil circuit to balance the circuit and maintain pressure, so that the descent speed does not change due to heavy objects. The throttle valve regulates the flow rate and the ascending and descending speed.

Small safe operation distance: Circuit voltage (kV) of external power lines<~~~ Small safe operation distance (m) Setting requirements: A small safe distance should be maintained between the outer edge of the construction electric elevator and the edge of the external overhead power line.Unloading platform and attached electric construction platform, etc.The entrance of each landing platform must be equipped with a landing door, which must open towards the landing platform side, and the door bolt must be set on the side next to the construction electric elevator.Management Department,Braking. The brake limit switch for partial motion control of the electric hoist traction machine. Assembly that restricts the operation of the lift car when it is opened to a high or low position; If the limit switch controls the overtravel switch. When the car travels to a high or low position, it will take on the function of raising or lowering. In order to prevent the lift car from crashing or sinking, stage equipment should be dismantled with over travel switches that can cut off power and cannot be automatically reset, it will take on the function of raising or lowering. In order to prevent the lift car from crashing or sinking rather than in the shaft; A buffer should be installed that can absorb the energy of the moving mechanism and reduce impact.The end height of the guide rail frame above the high attachment point should comply with the provisions of the user manual.Braking. The brake limit switch for partial motion control of the electric hoist traction machine. Assembly that restricts the operation of the lift car when it is opened to a high or low position; If the limit switch controls the overtravel switch. When the car travels to a high or low position, stage equipment should be dismantled with over travel switches that can cut off power and cannot be automatically reset, rather than in the shaft; A buffer should be installed that can absorb the energy of the moving mechanism and reduce impact.

The connection method and angle between the wall bracket and the building structure should comply with the requirements of the user manual.Create brilliance,Drainage measures need to be considered around the foundation. (Drain the accumulated water on the foundation).The isolation and buffering rubber in various parts of the aluminum alloy electric elevator drive device are intact and tightly fitted.During normal operation,MaastrichtElectric light lift, the horizontal distance between the closed cage door and the closed landing door should not exceed mm. Otherwise,MaastrichtElectric small elevator, measures should be taken to make it meet the requirements, or side protection devices at the entrance of the landing station that meet the requirements should be equipped. The distance between any opening between the side protection device and the hanging cage or landing door should not exceed mm.Maastricht,Safety performance: Electric elevators not only have the safety device of traditional traction elevators, but also have an overflow valve to prevent excessive system pressure during upward movementIn addition to ground protective fences, low level doors can be used. Low level doors should meet the following requirements: the height of the door should be between m and m. And there should be at least protective railings, a half height middle crossbar, and a toe board at least mm above the ground.Emergency manual valve: In case of power failure it can cause the car to descend to the nearest floor position and open the door
