Installation and precautions of hydraulic lifting column

Notes for installation of hydraulic lifting column

1. Digging foundation holes:

Dig the foundation pit according to the outline size of the product. The size of the foundation pit: length: determine the size according to the situation of the road on site;

Width: 600 --80 m;

Depth: 140m m(including a seepage layer of 300mm).

2. Make seepage layer:

After mixing with sand and gravel, make 300mm permeable layer from the bottom of the foundation pit upwards. The permeable layer shall be paved and tamped to prevent the equipment from sinking.

(If possible, choose gravel below 10mm instead of sand.)

According to the different conditions of the region to choose whether to do drainage.

3. Leveling the outer cylinder of the product by unloading:

Remove the outer barrel with hexagon socket and place it on the seepage layer. Adjust the levelness of the outer barrel. Make the upper surface of the outer barrel slightly higher than the ground plane for 3-5mm.

4. Embedded wire pipe:

Embed the threading pipe according to the position of the outlet hole reserved on the surface of the outer barrel.

The diameter of threading pipe shall be determined according to the number of lifting columns. Generally, each lifting column shall require one cable of 3*1.5 power line and one control line of 2* 0.75 pressure relief solenoid valve. If there is a lamp belt, and one more cable of 2*0.5 power line, the specific use shall be determined before construction according to the needs of customers and the difference of distribution.

5. Debugging:

Switch on the circuit of the equipment, operate the rising and falling, observe the rising and falling of the equipment, adjust the rising height of the equipment, and check whether the equipment has oil leakage phenomenon.

6. Fixed equipment and pouring:

Put the equipment into the pit, backfill the appropriate amount of sand, fix the equipment with stones, and then pour the equipment with C40 concrete slowly and evenly until it is level with the upper surface of the equipment.

Notes for use of hydraulic lifting column

1. The remote control controls the rise and fall of the cylinder body :(it can be installed according to different needs of customers)

There are three buttons on the remote control: up, down and stop.

The remote control can be used to make the device rise and fall. The stop key can be used to stop the action of the device before the action is completed.

2. Distribution box buttons control the rise and fall of cylinder body:

The surface of the box body is provided with up, down and stop buttons.

The use of this button can make the device rise and fall, Wuwei lifting column, in the action is not completed during the stop key can be used to achieve the device to stop the action

3. The external button box controls the lifting of the cylinder body:

This button can be used to make the device go up and down. During the action is not completed, the stop key can be used to realize the device action stop.

When the equipment is in the rising state and the power grid is cut off, the distribution box control system cannot be started normally due to the power cut off.

The distribution box is equipped with 12 V lead-acid battery, in order not to affect the normal traffic of vehicles, usually press the pressure relief combination button -- the drop button and the stop button on the box at the same time, if the cylinder does not move or slide down for a period of time, the downward pressure can be artificially applied until the cylinder drops to the ground level.

Daily precautions for hydraulic lifting column

(1) Avoid frequent lifting within a short time, otherwise the motor will be heated and damaged.

(2) Pay attention to pedestrians during ascending operation to avoid injury.

(3) When the cylinder is not working normally, press the stop button once after the rise and fall, so as to avoid the damage of electrical components and the failure to stop, which will cause the motor to burn out.

(4) In the process of use, if it is found that individual lifting column is much higher than other columns, should immediately press the stop button, and observe whether the motor is still working, when the motor has been confirmed to stop, timely contact with the factory.

(5) It is strictly prohibited to fill the gap around the column with silt and debris, so as not to affect the normal lifting of the column.

(6) It is strictly prohibited to carve on the surface of the column. Automatic lifting column will cause damage to the column.
