Stage equipment safety door. To prevent personnel from extending their heads, hands, and feet out of the shaft and objects from falling into the vertical shaft. Its vertical position should be closed, its cabin should be full of doors, and the height of the hoistway (hall door) should not be less than meters; The electric door opening and closing switches should be removed from the vertical and passenger compartment doors. In order to prevent accidents caused by vertical, passenger car doors, and car roof doors not being closed.; Door interlocks should be installed on both the vertical and passenger compartment doors.The end height of the guide rail frame above the high attachment point should comply with the provisions of the user manual.Philadelphia,The magnetic directional valve returns to the fuel tank. To ensure stable landing 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 landing speed does not change due to heavy objects. It is adjusted by the saving valveNews Abstract: The development of the lifting platform industry will continue to grow in recent years! With the continuous development of electric lifting machinery for high-altitude operations in recent years, the products of electric lifting platform vehicles have been continuously improved, and various new technologies and materials have emerged, making the further development of lifting platform vehicles possible.Luchingu,Use floor doors and cage door devices on construction sites where conditions permit.Low level doors should be equipped with interlocking devices that can verify their closed and locked positions. The action of this interlocking device should be at the entrance of the cage. Simple use should not interfere with the operation of the interlocking device. The attached wall bracket should use matching standard products. When the wall bracket cannot meet the requirements of the construction site it should be designed separately. The design of the wall bracket should meet the requirements of component stiffness,PhiladelphiaSan Severo , strength, stability, etc., and the production should meet the design requirements.The foundation production and acceptance of electric elevators for foundation construction should comply with the user manual and regulatory requirements.

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.Correct use can also greatly improve work efficiency. So how should it be used?Work is essential, guardrails, protective covers, platforms and stairs, etc.Workshop cost,Flat screw mechanical electric lifting mechanism: The lifting platform of this structure has the advantages of small civil engineering coordination, shallow foundation pit required, large stroke, stable operation, low noise, accurate positioning, and low cost. Adopting a horizontal screw drive and a scissor fork structure to achieve the lifting motion of the table, it can be stopped arbitrarily within the range of travel.High lifting height, using side mounted oil cylinders stable operation, noise free, easy maintenance and longer service life.The use of standard section connecting bolts should comply with the user manual and specification requirements.

Pipeline rupture valve: When the hydraulic system pipeline ruptures and the car stalls and descends, it can automatically cut off the oil circuit and stop descentQuality assurance,PhiladelphiaUdinese, 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, small size, and space saving; Increased the service life of electric elevator pipelines and solved the problem of easy oil leakage.The upward movement of the hydraulic cylinder involves lifting heavy objects, and the return oil from the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve. The additional pressure relief valve is used for adjustment,Setting requirements: The wall bracket should use the manufacturer's matching standard products.When a rigid mm square or circular flat surface is applied with a normal force of N to either side of the door, the door may not meet the above requirements,PhiladelphiaMannheim, but safety should be maintained.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.
