MingshanElectrThe 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.
When the wall bracket adopts non matching standard products, design calculations should be carried out.
Mingshan.Setting requirements: The up travel (limit) switch should be able to automatically stop the cage running at the rated speed before reaching the upper limit switch, but should not trigger the up travel (limit) switch as high
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.
.From the perspective of the safety performance of the machinery itself,MingshanElectric vertical elevator, those that have undergone national safety certification will not have significant safety issues. The main problem is that after using the electric elevator for a period of time, mechanical components may fall off or be damaged due to various factors. This problem depends on regular inspection and maintenance of the machinery
Braking. The brake limit switch for partial motion control of the electric hoist traction machine. Assembly that restricts the operation of the lift car when it is opened to a high or low position; If the limit switch controls the overtravel switch. When the car travels to a high or low position, it will take on the function of raising or lowering. In order to prevent the lift car from crashing or sinking, stage equipment should be dismantled with over travel switches that can cut off power and cannot be automatically reset, and installed in the machine room,MingshanSmall electric pulley elevator, rather than in the shaft; A buffer should be installed that can absorb the energy of the moving mechanism and reduce impact.
Work is essential, and the main protective accessories include safety belts, guardrails, protective covers, platforms and stairs, etc.
Model Example: Hanging Cage Specification: LABSC200/200TD3200x1500 Type I: 2900~3600 Type II: 2900~3600 Type V: 1800~250044003800 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) x0.02 (kN).
In addition to fixed modes,MingshanElectric hydraulic folding elevator, there are also types of car mounted mobile devices. As the name suggests this type of lifting device is a combination of lifting equipment and car mounted systems. It is very flexible to move, and of course, it is better to use it. For example, there are such lifting devices in airports, and car stations or sports stadiums may also be equipped with such devices, as they can be moved, but can be used wherever lifting operations are required. For example, when installing outdoor advertisements some advertisements are relatively high in height. At this time, currently mobile lifting equipment can be used to transport billboards or staff to the designated height for work. This type of equipment can also be divided into two types based on the driving mode: hydraulic lifting and electric lifting. The so-called hydraulic lifting is the use of hydraulic oil to drive and reach a specified height. The electric mode is driven by a motor or teeth to lift to a certain height. However, hydraulic lifting platforms are more widely used.
Construction electric elevators should be equipped with cable guide frames and comply with regulatory requirements.
Workshop cost.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 1m and 2m. And there should be at least protective railings, a half height middle crossbar, and a toe board at least 150mm above the ground.
The scaffolding of the parking platform should be laid tightly and firmly.
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 function of the lifting platform in a theater is roughly as follows: the main lifting platform arranged in the main performance area of the stage is mainly used to quickly change the scenery. Typically, with&quo; Product; In the music and dance theater stage arranged in a zigzag pattern, the lifting platform, side car platform, and rear car turntable perform a rapid transformation of the entire or partial scene. This arrangement allows for rapid switching of three full sets.
Information recommendation.The landing door should meet the requirements of the specifications and achieve standardization.
The cargo is 0.5m.
Work is essential, and the main protective accessories include safety belts, guardrails, platforms and stairs, etc.
Mingshan.Human improper operation is the main factor causing malfunctions in scissor type electric elevators. When stacking goods, electric elevators should stack the goods neatly, which is better than stacking them in the center of the cargo stacking area of the cargo elevator to avoid imbalance between the two ends of the stacking area. Eventually, during the operation of the electric elevator, it may cause the electric elevator to lose balance. After the goods are stacked completely, ropes should be used to lock the goods, 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
Small safe operation distance: Circuit voltage (kV) of external power lines<11~1035~110220330~550 Small safe operation distance (m) 4681015 Setting requirements: A small safe distance should be maintained between the outer edge of the construction electric elevator and the edge of the external overhead power line.
