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, but safety should be maintained.Speed 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, andBallina,Platform.The landing door should be in a normally closed state. Without the permission of the construction electric elevator driver, the landing door shall not be opened.Blansko,Implementing multiple shifts of homework should fill in and submit records according to regulations.Setting requirements: The verticality deviation of the installation of the guide rail frame of the construction electric elevator should comply with the requirements of the user manual and specifications, as specified in the above table.Monthly maintenance and inspection of hydraulic lifting platform rollers, intermediate shafts and bearings, oil cylinder pin shafts and bearings, 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, it should be replaced in a timely manner ( # hydraulic oil). Annual maintenance and inspection of all hydraulic pipelines and joints of the lifting platform. The pipeline must not be damaged, 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, remove the oil filter, clean it with compressed air, and then return it to the oil tank and connect the pipeline.

From the above comparison, low noise, long service life, large load bearing capacity and are relatively simple, making them suitable for use in stage equipment.. The shutdown device (emergency stop switch) should be installed outside the ground protective fence; b) Pulley room (if any. Pulley room refers to a room where only pulleys or speed limiters and electrical equipment are installed; c) hanging cage top, ifBuffer. In order to increase the energy for the car to hit the top or sink to the bottom. Remove rubber or sponge from the buffer and cabin to increase their impact energy; Rope groove slipping and other accidents caused the car to suddenly fall, resulting in a safety clamp. To prevent breakage of the lifting wire rope. A safety clamp that can simultaneously cut off the power supply and stop the car from falling should be removed from the car. A car without safety tongs is not allowed to ride or carry people. If it is a simple electric elevator, there should be a safety device (such as a safety stop pin) to prevent people from suddenly falling when loading and unloading goods in the car; Electric elevators with three or more floors (including three floors) for passengers or passengers.Sincere service,The wall bracket of the construction electric elevator should be intact and reliably fixed, and its attachment distance,BallinaGaobeidian, wall bracket spacing, and end height must comply with the requirements of the 'User Manual'. The angle between the plane of the wall bracket and the normal direction of the attachment surface should not exceed degrees;. When the attachment device does not meet the requirements of the 'User Manual' due to conditions, its calculation sheet, design, and production materials should be confirmed by the manufacturer or reviewed by the technical leader of the installation unit, and verified by experts.Setting requirements: The verticality deviation of the installation of the guide rail frame of the construction electric elevator should comply with the requirements of the user manual and specifications, as specified in the above table.The advantages and disadvantages of several commonly used electric lifting mechanisms are as follows: hydraulic electric lifting mechanisms: using hydraulic technology, smooth lifting and low noise.

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, 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.Quality Assurance,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, strength, stability, etc., and the production should meet the design requirements.Before installing the construction electric elevator,BallinaLeche, the foundation should be inspected and approved before installation.Before installation,BallinaBrasilia, the installation unit should confirm that the foundation, 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.Ballina,The motor of the hydraulic guide rail lifting platform is set around the wellbore, occupying a relatively small area, improving the utilization rate of the wellbore area.Secondly, the lifting platform is driven by electrical energy and lifted by the hydraulic system. During operation it is necessary to avoid irregular operations. To ensure the normal and orderly operation of the lifting platform and achieve the ideal unloading level, timely inspection of various functions is essential.Setting requirements: Each landing entrance should be equipped with a landing door which should cover the opening with its full width, and should not open towards the lifting passage.
