EvlerHand prop
EvlerElectric 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), and
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,Evler1 ton electric elevator, 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.
Evler.Afterwards, it should be scrapped.
The counterweight guide rail should meet the specification requirements.
.The foundation production and acceptance of electric elevators for foundation construction should comply with the user manual and regulatory requirements.
The end height of the guide rail frame above the high attachment point should comply with the provisions of the user manual.
Drivers of construction electric elevators should hold special construction operations and are not allowed to operate without a certificate.
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.
The isolation and buffering rubber in various parts of the aluminum alloy electric elevator drive device are intact and tightly fitted.
Setting requirements: The spacing of wall brackets along the vertical direction should comply with the provisions of the user manual.
Marketing Department.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.
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.
From the perspective of the safety performance of the machinery itself, 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
Principle of electric elevator rotary valve: When the electric elevator rises, the rotary valve will automatically open. To close the plug valve,EvlerElectric fork lift table, it is necessary to first turn the handle to turn the plug to a 90 degree position until it is closed, and then turn the transmission handwheel to lower the plug and achieve sealing.
Create brilliance.Once again weekly inspections should be conducted to check whether the connecting screws at various parts of the lifting platform are tightened, whether there is a lack of hydraulic oil whether the sealing rings are damaged or ineffective, and whether the oil cylinder is leaking. It is necessary to clean the lifting frame, scissors, wiring, and oil cylinder once a week to avoid dust and debris affecting normal operation.
.
Work is essential, and the main protective accessories include safety belts, guardrails, protective covers, platforms and stairs, etc.
Evler.The net height of the landing door opening should not be less than 8m,EvlerElectric tripod elevator, and the difference between the net width and the outlet width of the cage door should not exceed 120mm. When the floor door is closed, except for the gap between the lower part of the door that should not exceed 35mm, 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, should comply with the provisions of Table 4 of 'Mechanical Safety - Safety Distance to Prevent Upper and Lower Limbs from Touching Dangerous Areas' GB23821-2009.
When the foundation is set on the roof or floor structure, the bearing capacity of its supporting structure should be checked.
The hydraulic oil forms a certain pressure by the vane pump, and enters the lower end of the hydraulic cylinder through an oil filter, throttle valve, hydraulic control one-way valve, and balance valve, causing the hydraulic cylinder to move upwards and lift heavy objects. The return oil at the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve, and its rated pressure overflow valve is adjusted. The pressure gauge observes the reading value on the pressure gauge. The downward movement of the hydraulic cylinder (i.e. lowering of heavy objects).
