The pump body adopts an integrated pump station， all equipped with imported high-quality pump stations， the horizontal distance between the edge of the cage door and the edge of the landing station should not exceed mm.
OffenbachThe suspension cage movement can only be resumed after operator operation.
The safety notice board for construction electric elevators should be prominently placed on the hanging cage for the rated load capacity and rated number of passengers of the construction electric elevator. It is strictly prohibited to use construction electric elevators beyond the rated load capacity or rated number of passengers.
BellattiSpeed limiter. To prevent the driving speed from exceeding the normal speed. A speedometer should be installed (not required for floors below or including the second floor)， which is an individual mechanism that is integrated with a safety clamp; The entrance and exit of the passenger compartment should be equipped with safety doors. Public places family dormitories， and
When the foundation is set on the roof or floor structure， the bearing capacity of its supporting structure should be checked.
Speed limit wire rope switch. When the speed limit wire rope trips or breaks. Make the electric elevator unable to start.
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.
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.
Advantages of electric elevator rotary valve: Simplify the installation of electric elevator pipelines; The operation is more convenient， and the valve can be opened and closed at any time; The installation of a rotary valve reduces the friction of the sealing components; Compact structure，OffenbachElectric one ton elevator， small size， and space saving; Increased the service life of electric elevator pipelines and solved the problem of easy oil leakage.
Quality assuranceTo meet the needs of stage craftsmanship and layout; Product; In the music and dance theater stage arranged in a zigzag pattern， auxiliary lifting platforms are often arranged in front， back，OffenbachScissor fork electric elevator， left，Offenbach4 meter high electric elevator， and right of the main stage lifting platform. The side and rear auxiliary lifting platforms are used for the smooth opening of the side platform and rear vehicle turntable， while the front auxiliary lifting platform is used to place the rear vehicle turntable near the platform entrance. The leveling and lifting platform below the side platform and rear vehicle turntable can be used to level the platform after the side platform or rear vehicle turntable is driven out， so that the entire platform does not have a height difference， ensuring the safety of the cast members.
Drivers of construction electric elevators should hold special construction operations and are not allowed to operate without a certificate.
From the above comparison it can be seen that hydraulic electric lifting mechanisms have stable lifting， low noise， long service life， large load bearing capacity， and are relatively simple， making them suitable for use in stage equipment.
Once again， weekly inspections should be conducted to check whether the connecting screws at various parts of the lifting platform are tightened， whether the sealing rings are damaged or ineffective， whether there is a lack of hydraulic oil， and whether the oil cylinder is leaking. It is necessary to clean the lifting frame， scissors， wiring， and oil cylinder once a week to avoid dust and debris affecting normal operation.
consumptionThe safety bulletin board for construction electric elevators should be hung at the protective shed of the electric elevator， with a size of meters by meters.
Electric elevators should be regularly maintained and cleaned. During maintenance and cleaning， which is an individual mechanism that is integrated with a safety clamp; The entrance and exit of the passenger compartment should be equipped with safety doors. Public places， family dormitories， and

There is no need to set up a computer room above the shaft like an elevator， and the top floor height can be installed at least . meters.
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
