The full height landing door should meet the following requirements: the net height of the landing door opening should not be less than 0m. In special circumstances, it is allowed to lower the height of the lower door opening, but in any case, the net height of the lower door opening is not less than 8m. (Article 1 of GB26557-2011)
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, so that they are not afraid of the goods during the lifting process; Careless; Scattered down
The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve and the return oil from the lower end of the hydraulic cylinder returns to the oil tank through the balance valve, hydraulic control one-way valve, throttle valve, and explosion-proof electromagnetic directional valve. To ensure a smooth descent of heavy objects and safe and reliable braking, a balance valve is installed on the return oil circuit to balance the circuit and maintain pressure, so that the descent speed does not change due to heavy objects. The throttle valve regulates the flow rate and the ascending and descending speed.

When a rigid 5000mm2 square or circular flat surface is applied with a normal force of 600N to either side of the door, the door may not meet the above requirements, but safety should be maintained.
recommend.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: The installation and dismantling workers electricians, and other operators of construction electric elevators should have special construction operations.
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, rather than in the shaft; A buffer should be installed that can absorb the energy of the moving mechanism and reduce impact.
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.
Respect for customers.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.
Electric lifting machinery, as an important product of social development in China, has a high social status and has now become an irreplaceable operational tool in our mainstream goods. The hydraulic pump station is the heart position of electric lifting machinery, which greatly tests the professionalism and attention of operators. It is our common responsibility to inspect it and ensure the daily use of machinery. Let's take a look at a few common sense issues: the manufacturer of electric elevators is to ensure the correctness of the power connection, and there should be no misconnection or leakage; Pay attention to cleaning work in daily life and do not allow stains to corrode it; When standing still, regular maintenance should be carried out to prevent the impact of rain and snow weather; Overloading is the first thing that operators must comply with; Iron Law&# quo;; The adjustment of the solenoid valve cannot be done arbitrarily and must be checked and certified by a professional organization; Especially when conducting outdoor operations under high temperatures, it is necessary to always pay attention to the abnormalities of the pump station; It is very normal for us to encounter some problems when using hydraulic boarding bridges, as long as these problems are not very serious, we don't have to worry too much. However, when there is a problem with the hydraulic boarding bridge, only a timely solution is the correct response. Below is an introduction to some common faults of the hydraulic boarding bridge and specific solutions: the hydraulic boarding bridge must be repaired while hanging and supporting the working platform of the lifting platform to avoid sudden descent of the lifting platform, causing unnecessary casualties; 2. Do not adjust the overflow valve arbitrarily. Because every component in the hydraulic system operates at a specified pressure, once the relief valve is adjusted, it may cause abnormal operation of the hydraulic system, causing unnecessary damage to people, and objects; Non professional personnel are not allowed to disassemble electrical appliances at will to prevent electric shock or incorrect connection.
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.
Proskov.When the horizontal distance between the edge of the cage and the edge of the landing or between the cage and the landing door is greater than 150mm and there is no effective protection from other structures, the main feature is that the equipment occupies a small foundation pit and has a large stroke. The equipment has a height of only 200-500mm and a travel distance of up to 14m. It is particularly suitable for buildings with stages built on two or more floors due to space constraints.
