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,HowardPoitiers, should comply with the provisions of Table of 'Mechanical Safety - Safety Distance to Prevent Upper and Lower Limbs from Touching Dangerous Areas' GB-.In addition to ground protective fences low level doors can be used. Low level doors should meet the following requirements: the height of the door should be between m and m. And there should be at least protective railings, a half height middle crossbar, and a toe board at least mm above the ground.Howard,The working principle of the aluminum alloy lifting platform is that hydraulic oil is composed of a vane pump to form a certain pressure, which enters the lower end of the hydraulic cylinder through an oil filter, throttle valve, hydraulic control one-way valve, and balance valveThe setting of the cable guide frame should comply with the user manual and regulatory requirements.San-Mateo-Ixtatan,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.Steel wire ropes, pulleys, and counterweight steel wire ropes shall comply with the following regulations: the characteristics of steel wire ropes shall comply with the requirements of General Purpose Steel Wire Ropes GB/T; Maintenance, wear, deformation, and corrosion of steel wire ropesThe use of standard section connecting bolts should comply with the user manual and specification requirements.

Electric elevators used in various places.When a suspension cage with a rated load capacity acts on the buffer at a speed greater than the rated speed of .m/s, the average deceleration of the suspension cage should not exceed g, and the time when the peak deceleration exceeds g should not exceedHigh lifting height, using side mounted oil cylinders, stable operation, noise free, easy maintenance, and longer service life.Recommendation and consultation,Many theaters use a lifting platform as a vertical transportation tool for goods. The rear of the main stage or the end of the side stage in many theaters are equipped with a set container transportation lifting platform which is used to vertically transport items from the ground to a designated location or even the stage plane. The lifting platform of the music pool is often used for transporting movable seats, etc.Setting requirements: The anti loosening and anti loosening parts between the connecting parts should comply with the provisions of the user manual and should not be replaced by other objects. For connecting bolts with pre tightening requirements, a torque wrench or special tool should be used to accurately tighten the bolts to the specified torque value according to the specified tightening sequence. When installing standard section connecting bolts, it is advisable to place the screw at the bottom and the nut at the top.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.

Acceptance: Concrete strength grade C,HowardEnnis,The counterweight guide rail should meet the specification requirements.And the decoration team is also using aluminum alloy electric elevators. What safety considerations should we consider during the use process? Many manufacturers have not clearly indicated it. Today the mechanical editor will talk to you about aluminum alloysSetting requirements: The anti loosening and anti loosening parts between the connecting parts should comply with the provisions of the user manual and should not be replaced by other objects. For connecting bolts with pre tightening requirements, a torque wrench or special tool should be used to accurately tighten the bolts to the specified torque value according to the specified tightening sequence. When installing standard section connecting bolts, it is advisable to place the screw at the bottom and the nut at the top.Howard,HowardAvignon,During loading and unloading, the horizontal distance between the edge of the cage door and the edge of the landing station should not exceed mm.Every theater is a public place with a large number of people, and safety considerations should be taken into account in stage design. According to relevant national regulations, in order to prevent accidents caused by the crushing of electric elevators or improper control by drivers. Electric elevators should be equipped with the following necessary safety devices to ensure that the car of the electric elevator stops rising or falling in a timely manner.Setting requirements: The spacing of wall brackets along the vertical direction should comply with the provisions of the user manual.
