Hu GewenSelf pThe angle between the wall bracket and the horizontal plane should comply with the requirements of the user manual.
The counterweight guide rail should meet the specification requirements.
Hu Gewen.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, can the folding arm electric elevator provide greater torque output, 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?
The foundation production and acceptance of electric elevators for foundation construction should comply with the user manual and regulatory requirements.
.Setting requirements: The foundation and foundation of the construction electric elevator should meet the requirements of the user manual. Before installing the construction electric elevator, 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.
Before installation, the installation unit should confirm that the foundation, foundation bearing capacity, embedded parts, concealed engineering acceptance form and concrete strength report.
According to the needs of different performance genres, the form of the stage can be changed. For example, using an orchestra pit lift can combine a framed stage with a large lip or even an extended stage. In an experimental theater, using a lift can make the theater have various forms such as an end stage, an extended stage, an island stage, an intermediate stage, a T-shaped stage, or a hall.
Tank oil temperature protection: When the oil temperature in the tank exceeds the standard setting value, the oil temperature protection device sends a signal to suspend the use of the elevator. The elevator can only be started when the oil temperature drops
Setting requirements: Construction electric elevators should be equipped with up travel (limit) switches.
Installation and dismantling personnel and drivers should hold certificates to work.
Highly recommended.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.
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, it can achieve the lifting of a double-layer tabletop. Multiple lifting platforms can be formed as needed the side protection device for the landing entrance should be equipped.
Vertical lead screw electric lifting mechanism: Adopting a lead screw transmission method, Terrace, Tower, Pavilion; Ideal props.
Steel 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
Job description.When the door is closed, except for the gap between the lower part of the door that should not exceed 35mm, any through-hole and opening size related to the distance between any door and adjacent moving parts, as well as the gap around the door or the gap between parts,Hu GewenLarge electric elevator, should comply with the provisions of Table 4 of GB 23821-2009.
The upward movement of the hydraulic cylinder involves lifting heavy objects, and the pressure gauge reads the value when observing the pressure gauge
The motor of the hydraulic guide rail lifting platform is set around the wellbore,Hu GewenElectric brick elevator on construction site, occupying a relatively small area, improving the utilization rate of the wellbore area.
Hu Gewen.Installation verticality deviation guide rail frame erection height, h/mH≤ 7070100150H& gt; 200 verticality deviation/mm≤ (1/100h≤ 70≤ 90≤ 110≤ 130 pairs of steel wire rope construction electric elevators, the verticality deviation of the guide rail frame should not exceed (5/1000) h.
The list of materials for making landing doors is as follows: Table 1: List of materials for making landing doors. Landing doors should be installed at the entrance of each landing station, and the landing doors should function properly.
Before installation, the installation unit should confirm that the foundation, foundation bearing capacity, embedded parts,Hu GewenElectric banner elevator, 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.
