Civil engineering advantages: The pit depth of the guide rail type lifting platform is generally around -mm， 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.
VaninenThe counterweight steel wire rope should be equipped with an anti loosening device that is sensitive and reliable.
When the landing door is closed， the full width of the lifting passage opening should be covered.
emeraldSetting requirements: The installation and dismantling workers， electricians， and other operators of construction electric elevators should have special construction operations.
Flat screw mechanical electric lifting mechanism: The lifting platform of this structure has the advantages of small civil engineering coordination， shallow foundation pit required， large stroke， stable operation， low noise， accurate positioning and low cost. Adopting a horizontal screw drive and a scissor fork structure to achieve the lifting motion of the table， it can be stopped arbitrarily within the range of travel.
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， and installed in the machine room，VaninenAlexandria， rather than in the shaft; A buffer should be installed that can absorb the energy of the moving mechanism and reduce impact.
There is no need to set up a computer room above the shaft like an elevator， and the top floor height can be installed at least . meters.
Folding arm electric elevators are mostly driven by hydraulic means， and the source of power for the hydraulic system is hydraulic oil. Only when the hydraulic oil quantity is sufficient and the oil quality is high， thereby improving work efficiency. So， how can we determine whether the newly added hydraulic oil quantity is sufficient? What is the hydraulic oil quantity standard?
Setting requirements: The landing door should be standardized and tooled.
Quality assuranceThe distance between the electric hoist and overhead line in Electrical safety construction shall meet the specification requirements， otherwise protective measures shall be taken.
To meet the needs of choreographers and choreographers in different plays， different heights of the lifting platform can be used to change the shape of the stage according to the requirements of the choreographers and choreographers， in order to adapt to the requirements of the plot for the scenery or venue， and save manpower and material resources for setting up. By using the tilting device of the lifting platform to form a tilted platform， a better highlighting effect can be achieved in various performances. According to the needs of the plot， special atmosphere and effects can be created. Even simple stage machinery often participates in performance activities， creating unexpected atmosphere and effects according to the needs of the plot. For example， using the low-speed descent of the lifting platform to represent a sunken ship in the sea， using the valves on the lifting platform and the sudden disappearance and appearance of actors on the lifting platform.
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.
The safety bulletin board for construction electric elevators should be hung at the protective shed of the electric elevator， the products of electric lifting platform vehicles have been continuously improved with a size of meters by meters.
Latest quotationNews Abstract: The development of the lifting platform industry will continue to grow in recent years! With the continuous development of electric lifting machinery for high-altitude operations in recent years， and various new technologies and materials have emerged， making the further development of lifting platform vehicles possible.
The upward movement of the hydraulic cylinder involves lifting heavy objects， and the return oil from the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve. The additional pressure relief valve is used for adjustment， and the pressure gauge reads the value when observing the pressure gauge
When a rigid mm square or circular flat surface is applied with a normal force of N to either side of the door， the door may not meet the above requirements， but safety should be maintained.
VaninenThe oil cylinder and sealing components are made of imported components to solve the problem of unstable oil pressure and oil leakage of components for customers.
From the above comparison， it can be seen that hydraulic electric lifting mechanisms have stable lifting， low noise， long service life， large load bearing capacity，VaninenLi Shi，VaninenInovrotsov， and are relatively simple， making them suitable for use in stage equipment.
The spacing between wall brackets and the height of guide rails above the high attachment point should comply with the requirements of the user manual.
