Pipeline rupture valve: When the hydraulic system pipeline ruptures and the car stalls and descends, it can automatically cut off the oil circuit and stop descent
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),MaceElectric fixed elevator, 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, and the return oil from the lower end of the hydraulic cylinder passes through the balance valve, hydraulic control one-way valve, energy-saving valve, and explosion-proof electric valve
According to the needs of different performance genres, the form of the stage can be changed. For example, using an orchestra pit lift can combine a framed stage with a large lip or even an extended stage. In an experimental theater, using a lift can make the theater have various forms such as an end stage, an extended stage, an intermediate stage, a T-shaped stage, or a hall.
.Installation verticality deviation guide rail frame erection height, h/mH≤ 7070100150H& gt; 200 verticality deviation/mm≤ (1/100h≤ 70≤ 90≤ 110≤ 130 pairs of steel wire rope construction electric elevators, the verticality deviation of the guide rail frame should not exceed (5/1000) h.
Monthly maintenance and inspection of hydraulic lifting platform rollers, oil cylinder pin 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 40-50 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 (32 # 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.
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.
Drainage measures need to be considered around the foundation. (Drain the accumulated water on the foundation).
Alarm devices can be divided into fixed and mobile platforms, rail type and scissor type (curved arm type) to distinguish between overload or equipment malfunction. Fixed types include: scissor lift cargo elevator, chain electric elevator, and installation
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/T20118; Maintenance, wear, deformation, and corrosion of steel wire ropes
resources.The distance between the electric hoist and overhead line in Electrical safety construction shall meet the specification requirements, otherwise protective measures shall be taken.
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 0.75m; If the rated speed is not greater than 0.7m/s, the safety distance can be 0.40m.
Advantages of electric elevator rotary valve: Simplify the installation of electric elevator pipelines; The operation is more convenient, and the valve can be opened and closed at any time; The installation of a rotary valve reduces the friction of the sealing components; Compact structure, small size, and space saving; Increased the service life of electric elevator pipelines and solved the problem of easy oil leakage.
Civil engineering advantages: The pit depth of the guide rail type lifting platform is generally around 150-300mm, and the top layer is not affected. It can be customized according to the location and environment.
device management.When the door is closed, except for the gap between the lower part of the door that should not exceed 35mm, any through-hole and opening size related to the distance between any door and adjacent moving parts, as well as the gap around the door or the gap between parts, should comply with the provisions of Table 4 of GB 23821-2009.
Savings, rate of increase and decrease. To ensure safe and reliable braking and prevent accidents, a hydraulic control one-way valve,MaceElectric pull rod elevator, also known as a hydraulic lock, is added to prevent hydraulic pipelines from exploding and self locking safely. Installed overloaded voice control alarm
Before installation, the installation unit should confirm that the foundation, foundation bearing capacity, 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.
Mace.Then, the lifting platform platform platform that carries the load needs to be balanced and no deviation of one side is allowed. The lifting of goods does not allow people to stand on both sides of the platform, and the lifting of goods should try to maintain a stable and uniform speed.
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, and concrete strength report.
The connection method and angle between the wall bracket and the building structure should comply with the requirements of the user manual.
