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.

Protective measures should comply with regulatory requirements.

Dunkirk.The pressure joint between the pipe joint and the rubber hose fails prematurely, causing oil leakage or pipe explosion. The oil temperature rises due to frequent action of the overflow valve.

The safety bulletin board for construction electric elevators should be hung at the protective shed of the electric elevator, it can be seen that hydraulic electric lifting mechanisms have stable lifting, low noise, long service life, large load bearing capacity, and are relatively simple making them suitable for use in stage equipment.

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.

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.

Setting requirements: When the distance between the outer edge of the construction electric elevator and the external overhead power line cannot meet the requirements of a small safety distance,DunkirkManned electric elevator, the protective measures taken should comply with the specification requirements.

The up travel (limit) switch should be of the automatic reset type.

Setting requirements: The layout and installation of all cables and wiring of electric elevators should be able to prevent mechanical damage.

Honest management.Setting requirements: The guide rail should be rigid and flexible components such as wire ropes or chains should not be used.

The counterweight guide rail should meet the specification requirements.

The net height of the landing door opening should not be less than 8m, 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.

Implementing multiple shifts of homework should fill in and submit records according to regulations.

Bidding.The motor of the hydraulic guide rail lifting platform is set around the wellbore,DunkirkOutdoor electric lifting platform, occupying a relatively small area,DunkirkLadder type electric elevator, improving the utilization rate of the wellbore area.

Try to use this equipment in areas with wind force less than level five, and avoid using it when the wind force is too strong to avoid accidents.

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.

Dunkirk.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, deformation, and corrosion of steel wire ropes

The hydraulic oil forms a certain pressure by the vane pump, and enters the lower end of the hydraulic cylinder through an oil filter, explosion-proof electromagnetic directional valve, 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).

The motor of the hydraulic guide rail lifting platform is set around the wellbore, improving the utilization rate of the wellbore area.
