The foundation base or embedded parts should be fully embedded in the concrete foundation plate.Before operating the construction electric elevator, routine inspections should be carried out according to regulations and inspection records should be filled out.Middleburg,The up travel (limit) switch should be of the automatic reset type.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 movementHus,Operating cost advantage and low failure rate: Due to the use of advanced hydraulic systems and good methods, the operating failure rate can be reduced to a low level.When the landing door is closed, the full width of the lifting passage opening should be covered.Flat screw mechanical electric lifting mechanism: The lifting platform of this structure has the advantages of small civil engineering coordination, stable operation large stroke, 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.

When the foundation is set on the roof or floor structure, the bearing capacity of its supporting structure should be checked.The pressure joint between the pipe joint and the rubber hose fails prematurely, causing oil leakage or pipe explosion. The oil temperature rises due to frequent action of the overflow valve.During normal operation, the horizontal distance between the closed cage door and the closed landing door should not exceed mm. Otherwise, measures should be taken to make it meet the requirements,Acceptance: Concrete strength grade C, strength testing report.Setting requirements: Before starting work every day and changing shifts, the driver of the construction electric elevator should inspect the construction electric elevator according to the requirements of the user manual and specifications, record the inspection results, and report any problems found to the user unit.The hydraulic oil forms a certain pressure by the vane pump, and enters the lower end of the hydraulic cylinder through an oil filter, explosion-proof electromagnetic directional valve, throttle valve, and balance valve,MiddleburgDetroit, causing the hydraulic cylinder to move upwards and lift heavy objects. The return oil at the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve, and its rated pressure overflow valve is adjusted. The pressure gauge observes the reading value on the pressure gauge. The downward movement of the hydraulic cylinder (i.e. lowering of heavy objects).

Before operating the construction electric elevator, routine inspections should be carried out according to regulations and inspection records should be filled out.Recommendation and consultation,It is reported that a fixed electric elevator has good lifting stability and can only be used for fixed operations, making high-altitude operations easierThe impact load can cause early wear, fracture and fragmentation of mechanical structural components,MiddleburgWobzhe, as well as generate impact pressure in the hydraulic system, which in turn can damage hydraulic components, oil seals, and high-pressure oilThe foundation base or embedded parts should be fully embedded in the concrete foundation plate.Middleburg,Model Example: Hanging Cage Specification: LABSC/TDx Type I: ~ Type II: ~ Type V: ~ Technical Requirements: The load-bearing capacity of the foundation should be greater than P: P=(hanging cage weight+outer cage weight+total weight of guide rail frame+counterweight+load) x. (kN).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.The counterweight guide rail should meet the specification requirements.
