otherwise protective measures shall be taken.Secondly

The distance between the electric hoist and overhead line in Electrical safety construction shall meet the specification requirements 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, 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.Preacher,The top of the hanging cage is accessible; d) During installation/disassembly/maintenance/inspection of the device; e) Inside the hanging cage.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.Muktagacha,The use of standard section connecting bolts should comply with the user manual and specification requirements.The scaffolding of the parking platform should be laid tightly and firmly.Electric elevators used in various places.

Before 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,PreacherThree wheel electric elevator,PreacherElectric cargo elevator, and concrete strength report.Normal operation starts. Click on this free download of construction technical information. Safety limit devices should be installed on electric elevators for construction, with upper and lower limit switches that are sensitive and reliable.Setting requirements: The main connection methods between the wall bracket and the building include: connecting the wall bracket with the embedded parts on the wall; Fix with wall bolts; Embedded bolts; Welding with steel structures.ranking,Double layer steel mesh: The diameter of the steel bars is mm, with a spacing of mm.High lifting height, using side mounted oil cylinders, stable operation, noise free, easy maintenance,PreacherFully automatic electric elevator, and longer service life.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 hydraulic control one-way valve, and balance valve, 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).

Monthly maintenance and inspection of hydraulic lifting platform rollers, intermediate shafts and bearings, boom hinge shafts and bearings for wear. Add some oil to each part to extend the service life of the lifting platform bearings. The quality and level of hydraulic oil. The lifting platform should be raised throughout the entire process, and at this position, the hydraulic ground should be - millimeters higher than the bottom of the box. If the hydraulic oil becomes dark, sticky, or has foreign objects such as gravel, and the joints must not be loose. All joints must be tightened. Remove and disassemble the lowering valve of the lifting platform, blow out the plunger with compressed air, then install it and reinstall it. Drain and discard the hydraulic oil, tighten the joint, clean it with compressed air, and then return it to the oil tank and connect the pipeline.reform,The distance between the electric hoist and overhead line in Electrical safety construction shall meet the specification requirements, otherwise protective measures shall be taken.Setting requirements: A limit switch should be set at both the upper and lower ends of the stroke, which should be able to cut off the power supply before the suspension cage and other mechanical stop devices (such as buffers), so that the suspension cage can stopDrivers of construction electric elevators should hold special construction operations and are not allowed to operate without a certificate.Preacher,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.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 distance between the outer edge of the construction electric elevator and the edge line of the external overhead power line cannot meet the requirements in the table above, effective protective measures should be taken.
