Alvarden2 meteSteel 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
Vertical lead screw electric lifting mechanism: Adopting a lead screw transmission method, it can achieve the lifting of a double-layer tabletop. Multiple lifting platforms can be formed as needed, and different steps can be formed within the travel range to meet the needs of meetings and performances; Pavilion Terrace, Tower Pavilion; Ideal props.
Alvarden.The magnetic directional valve returns to the fuel tank. To ensure stable landing 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 landing speed does not change due to heavy objects. It is adjusted by the saving valve
Electric elevators used in various places.
.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, and
To meet the needs of stage craftsmanship and layout; Product; In the music and dance theater stage arranged in a zigzag pattern, auxiliary lifting platforms are often arranged in front, back, left, and right of the main stage lifting platform. The side and rear auxiliary lifting platforms are used for the smooth opening of the side platform and rear vehicle turntable, while the front auxiliary lifting platform is used to place the rear vehicle turntable near the platform entrance. The leveling lifting platform below the side platform and rear vehicle turntable can be used to level the platform after the side platform or rear vehicle turntable is driven out, so that the entire platform does not have a height difference, ensuring the safety of the cast members.
From the above comparison, it can be seen that hydraulic electric lifting mechanisms have stable lifting, low noise,AlvardenFully self-propelled electric elevator, long service life, large load bearing capacity, and are relatively simple, making them suitable for use in stage equipment.
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.
If the set screw is loose,Alvarden2 meter high electric elevator, be sure to pin it tightly to prevent accidents caused by the shaft pin falling off. Hydraulic oil should be kept clean and replaced every 6 months.
During normal operation, the horizontal distance between the closed cage door and the closed landing door should not exceed 150mm. Otherwise, measures should be taken to make it meet the requirements,AlvardenSmall electric hydraulic elevator, or side protection devices at the entrance of the landing station that meet the requirements should be equipped. The distance between any opening between the side protection device and the hanging cage or landing door should not exceed 150mm.
Quality inspection report.Double layer steel mesh: The diameter of the steel bars is 12mm, hands, and feet out of the shaft and objects from falling into the vertical shaft. Its vertical position should be closed, its cabin should be full of doors, and the height of the hoistway (hall door) should not be less than 8 meters; The electric door opening and closing switches should be removed from the vertical and passenger compartment doors. In order to prevent accidents caused by vertical, passenger car doors, which must open towards the landing platform side and the door bolt must be set on the side next to the construction electric elevator.
Alvarden.Operating cost advantage and low failure rate: Due to the use of advanced hydraulic systems and good methods, the operating failure rate can be reduced to a low level.
During loading and unloading, the horizontal distance between the edge of the cage door and the edge of the landing station should not exceed 50mm.
When a rigid 5000mm2 square or circular flat surface is applied with a normal force of 600N to either side of the door, but safety should be maintained.
