Emergency manual valve: In case of power failure it can cause the car to descend to the nearest floor position and open the doorBefore installation, the installation unit should confirm that the foundation, foundation bearing capacity, embedded parts, and foundation drainage measures of the installed construction electric elevator and auxiliary heavy equipment comply with the requirements of the special construction plan for the installation and dismantling of the construction electric elevator based on the construction electric elevator foundation acceptance form, concealed engineering acceptance form, and concrete strength report.Washington DCThe cargo is .m.Installation and dismantling personnel and drivers should hold certificates to work.Savalou,From the perspective of the safety performance of the machinery itself, mechanical components may fall off or be damaged due to various factors. This problem depends on regular inspection and maintenance of the machinerySafety 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 movementEmergency manual valve: In case of power failure, it can cause the car to descend to the nearest floor position and open the door

Setting requirements: The foundation and foundation of the construction electric elevator should meet the requirements of the user manual. Before installing the construction electric elevator, cargo elevator, double column aluminum alloy, three column and four column aluminum alloy. Can be used in factories automated warehouses, parking lots, municipal facilities, docks, buildings, and installationsPipeline rupture valve: When the hydraulic system pipeline ruptures and the car stalls and descends, it can automatically cut off the oil circuit and stop descentproperty right,Washington DCHollingole,The safety distance between the outer edge of the upper part of the landing door and the moving parts of the electric elevator during normal operation should not be less than .m; If the rated speed is not greater than .m/s, the safety distance can be .m.Installation and dismantling personnel and drivers should hold certificates to work.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.

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, strength, stability, etc., and the production should meet the design requirements.Variable cost,Washington DCInner Mongolia,Mechanical devices controlled by cage movement should not be used to open or close the landing door.Check whether the sealing of components such as the oil cylinder, oil pipe, and motor of the aluminum alloy electric elevator is good and whether there is any air leakage.To ensure safe and reliable braking of the lifting platform and prevent accidents, a hydraulic control one-way valve, also known as a hydraulic lock, is added to ensure safe self-locking in the event of an accidental rupture of the hydraulic pipeline. An overload sound control alarm has been installed to distinguish between overload or equipment failure. Electrical system explosion-proof button SB&flash; The rotation of the SB motor and the commutation of the explosion-proof electromagnetic directional valve are used to maintain load increase or decrease, and; Program adjustment time delay to avoid frequent movement of electric elevators that may affect their service life.Washington DC,The net height of the landing door opening should not be less than m, and the difference between the net width and the outlet width of the cage door should not exceed mm. When the floor door is closed, except for the gap between the lower part of the door that should not exceed mm, the size of any through-hole and opening related to the distance between any door and adjacent moving parts, as well as the gap around the door or between parts,Washington DCDalian, should comply with the provisions of Table of 'Mechanical Safety - Safety Distance to Prevent Upper and Lower Limbs from Touching Dangerous Areas' GB-.After the electric elevator passes the inspection, the user unit shall organize the leasing unit, installation unit, and supervision unit to conduct acceptance. For the implementation of construction general contracting, the acceptance shall be organized by the construction general contracting unit. The acceptance form should be signed by the relevant responsible person.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, rather than in the shaft; A buffer should be installed that can absorb the energy of the moving mechanism and reduce impact.
