The wall bracket of the construction electric elevator should be intact and reliably fixed， and its attachment distance， wall bracket spacing， and end height must comply with the requirements of the "User Manual". The angle between the plane of the wall bracket and the normal direction of the attachment surface should not exceed degrees;. When the attachment device does not meet the requirements of the "User Manual" due to conditions， its calculation sheet， design， and production materials should be confirmed by the manufacturer or reviewed by the technical leader of the installation unit， 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， 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，VigvanoHimsk， 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.
VigvanoThe movement of its related components is direct.
Mechanical devices controlled by cage movement should not be used to open or close the landing door.
Abu DhabiThe motor of the hydraulic guide rail lifting platform is set around the wellbore， occupying a relatively small area， improving the utilization rate of the wellbore area.
Setting requirements: Each landing entrance should be equipped with a landing door， which should cover the opening with its full width， and should not open towards the lifting passage.
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 and installed in the machine room， remove any obstacles or debris near the electric elevator that may hinder operation， and check whether the operating handle can be used normally.
The foundation production and acceptance of electric elevators for foundation construction should comply with the user manual and regulatory requirements.
new productThe verticality of the guide rail frame should meet the requirements of the specifications.
Especially suitable for steel structured factories， suitable for both indoor and outdoor installation.
Steel wire ropes， pulleys， and counterweight steel wire ropes shall comply with the following regulations: the characteristics of steel wire ropes shall comply with the requirements of General Purpose Steel Wire Ropes GB/T; Maintenance， wear， deformation， and corrosion of steel wire ropes
Setting requirements: The quality of the standard section should meet the requirements of the product manual. Before installing the construction electric elevator， all components should be inspected， and standard sections and other components with severe wear and deformation should be replaced.
Total quality assuranceMany theaters use a lifting platform as a vertical transportation tool for goods. The rear of the main stage or the end of the side stage in many theaters are equipped with a set container transportation lifting platform， which is used to vertically transport items from the ground to a designated location or even the stage plane. The lifting platform of the music pool is often used for transporting movable seats， etc.
The body in the lateral adjustment device of the driving plate should ensure a compressed state， so that the gear has a certain radial constraint， and ensure that the gear and rack always mesh well throughout the entire operation.
Steel wire ropes， pulleys and counterweight steel wire ropes shall comply with the following regulations: the characteristics of steel wire ropes shall comply with the requirements of General Purpose Steel Wire Ropes GB/T; Maintenance，VigvanoLamezia Terme， wear， deformation， and corrosion of steel wire ropes
VigvanoWhen applying a normal force of N to any position on either side of the door using a rigid mm square or circular flat surface in the locked position of the landing door， the door should be able to withstand and have no deformation; - Deformation not exceeding mm; After the test， it worked normally.
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.
Secondly，VigvanoStrasbourg， for the replacement of hydraulic oil on the lifting platform， it is recommended to replace it every three months. If the frequency of use is not high， it can be replaced once a year. The hydraulic oil must be clean and after changing the hydraulic oil， it must be automatically lifted and lowered to times to ensure that the air in the oil cylinder is completely discharged， maintain sufficient space， and ensure that the lifting platform can be lifted to the rated lifting height.
