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,HenanElectric boom elevator, 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.
Safety grounding device. In order to protect against electrical equipment. The metal casing of electrical equipment and the metal structure of electric elevators should be equipped with a safety grounding device. The grounding wire should operate multiple wires, and the neutral wire should not be arbitrarily held as a safety grounding wire. Its grounding resistance should not exceed 4 ohms; The power supply of the electric elevator can be cut off.
Henan.After the limit switch is activated,HenanElectric folding elevator, only professional personnel can restore the movement of the suspension cage; Limit switches and travel switches should not share the same triggering element; Limit switches should be either suspended or
With the continuous improvement of urbanization level in China, the number of high-rise buildings in urban areas has sharply increased, and the height of buildings has also continued to grow. This has created a demand for high-altitude lifting platform vehicles. Therefore, in order to meet the needs of the domestic market and the public, efforts will inevitably be made to design and produce high-altitude lifting platform vehicles.
.The landing door should meet the requirements of the specifications and achieve standardization.
Setting requirements: The quality of the standard section should meet the requirements of the product manual. Before installing the construction electric elevator, all components should be inspected and standard sections and other components with severe wear and deformation should be replaced.
The safety bulletin board for construction electric elevators should be hung at the protective shed of the electric elevator, with a size of 8 meters by 2 meters.
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.
Installation position of upper limit switch: Under normal working conditions, and 0.15m for SS type construction electric elevators (person)
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.
Finance Department.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), 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,HenanElectric passenger lift, and
Installation and dismantling personnel and drivers should hold certificates to work.
Low power consumption: When the hydraulic guide rail lifting platform descends, the foundation should be inspected and accepted according to the requirements of the specifications. Only after passing the inspection can the installation be carried out.
Quality inspection report.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.
Construction electric elevators should be equipped with lower limit switches that are sensitive and reliable.
Secondly, for the replacement of hydraulic oil on the lifting platform, it is recommended to replace it every three months. If the frequency of use is not high, it can be replaced once a year. The hydraulic oil must be clean and after changing the hydraulic oil, it must be automatically lifted and lowered 2 to 3 times to ensure that the air in the oil cylinder is completely discharged, maintain sufficient space, and ensure that the lifting platform can be lifted to the rated lifting height.
Henan.The L distance depends on the selected wall mount model.
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.
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.
