How to Install the Ultra-thin Scissor Lift

Ultra-thin scissor lift is a type of scissor lift, ultra-thin series scissor lift can be installed on the ground surface, without the need for pit pre-burial. Applicable to any repair shop, is the future mainstream products, foreign large-scale use of this type of products. Ultra-thin scissor lifts in the maintenance process bear the burden of lifting the vehicle, many times maintenance technicians need to work under the vehicle lifted up, ultra-thin scissor lift installation safety is particularly important. The following is to introduce the ultra-thin scissor lift on the ground requirements and installation process.

First, ultra-thin scissor lifts on the ground requirements

Situation one, the ground has ceramic tile and sand below: when the surface of the cement floor has ceramic tiles and ceramic tiles below the sand, ceramic tiles and sand accounted for a total of 3 centimeters thick, at this time we must test the thickness of the cement below, if it can reach 10-15 centimeters, and strength qualified, it can be directly installed, but the ground screws must be longer than 14 centimeters, the ground screw fixing requirements to grip the cement floor to reach at least More than 10 centimeters.

Situation two, store below the parking lot or basement: when the store below the basement or parking lot, this time to check whether the following buried rebar, the thickness of at least 10 centimeters, in the case of unburied rebar, the thickness of the cement floor at least 20 centimeters, in the case of buried rebar to reach more than 10 centimeters on the case, always remember that the strength of the cement floor is the most important, it must be reached! 210KG/MM, you can use the impact drill hole to see if it is a flour-like powder, if it is granular strength is unqualified!

Situation three, the strength of the cement floor failed (no basement and parking lot below): When we test the strength of the cement floor found to be unqualified, do not worry, ask the manufacturer or distributor to install the size of the map, in accordance with the size of the map will be dug out of the original cement and re-pouring of cement to achieve the strength will be qualified.

Situation four, the strength of the cement floor is unqualified (below the basement and parking lot): When we test the strength of the cement floor is found to be unqualified, first of all, we should check whether there is reinforcing steel underneath, such as reinforcing steel directly to the original cement dug up, must be in accordance with the manufacturers or dealers to provide the installation dimensions to dig up, digging up and directly after the pouring of the new qualified cement, after the drying out of the qualified. If there is no rebar, this case is more troublesome, you need to dig out the original unqualified cement, and then re-pour a layer of qualified cement, and must be thicker than before, pouring range in the installation location within a block.

In fact, compared to the double-column lifter, thin small shear for the foundation requirements or not high, it is mainly by the following block of steel plate base force, the four sides of the ground screws installed just to play a role in fixing the equipment to maintain a non-moving state, if you intend to buy a thin small shear first of all you have to dealers or manufacturers to communicate with the foundation of a good problem, such as determining that there is no problem with the foundation and then purchased and installed, in order to use a more assured and safer. Safety.

Second, the thin shear lifter installation process

First of all, prepare the tools you need to use: ultra-thin small shears, hydraulic oil 46 # 12kg, impact drills (with Φ19, Φ10, Φ4 drill bit), bucket, sledgehammer, screwdriver (a word, cross), level ruler, tape measure (7.5 meters), adjustable wrenches (12 ″), sharp-nosed pliers, spring pliers, plum wrenches: (8 #, 17 #), strong pliers, grease gun, socket wrenches: (28 #). )

Must have a voltage of 220V or more, power capacity must be greater than 2.2kw, wire diameter greater than 2.5mm, and must be well grounded.

Ground and concrete requirements: check the location where the lifter is to be installed, and check for cracks and broken concrete, the equipment must be installed in the bearing force of not less than 3,000 pounds / inch 2 (210kg / c ㎡), the thickness of not less than 100mm of concrete. After determining, start counting the accessories and put them in a sorted place.

Lifter location: According to the foundation plan requirements and installation size requirements, select a location that best suits your application, ensure that the space used is suitable for your lifter model and prepare the foundation.

Oil line installation: Set up the equipment according to the selected foundation and connect the oil line. Note: The position of the changeover valve handle is the normal working position.

Oil pipe quantity and parameters: 1/4 * 3720mm oil pipe (two straight), 1/4 * 3570mm oil pipe (two straight), 1/4 * 3480mm oil pipe (always a bend), 1/4 * 4730mm oil pipe (two straight), 1/4 * 4920mm oil pipe (two straight), 1/4 * 4980mm oil pipe (always a bend).

Circuit installation: Users adjust the current rating of the thermal relay in the electric control box according to the different configurations of the hydraulic station. In general, the set current of the thermal relay should be equal to or greater than the rated current of the motor. Adjust it to 12A when the voltage is 380V and 18A when the voltage is 220V.

Installation of high and low limit switches: High limit switch installation: the machine rises to 2000mm, when the slider touches the limit switch drive lever, the limit switch acts to stop the machine from rising, which is the highest height of lifting.

Installation of low limit switch: when the machine descends to 300mm and the buffer linkage touches the limit switch drive lever, the limit switch acts to stop the machine from descending, at this time, the machine can only descend and alarm by pressing the descent button and the bypass button at the same time.

Adjust the level of the machine: Measure with a leveling tape, and then pad the leveling pad to adjust the level until the two top plates are level before and after.

Installation of Scissor Lifter Ground Screws: Lift the machine to 1000mm to facilitate the drilling and installation of ground screws. Drill all the holes with an impact drill and install the ground screws, hammer the ground screws into the ground, and tighten the ground screws with a torque wrench to tighten the nut. *Note: The torque of fastening the ground screw is 150N.m, and the ground screw is knocked into the ground at least 90mm.

Installation of the oil pipe cover and install the control cabinet ground screws: organize the oil pipe and wires, cover the oil pipe cover and the control cabinet will be set up, the control cabinet installation position can be selected as shown in the figure, the use of screws and adhesive particles to fix the oil pipe cover.

Equipment commissioning:

1, first check the installed oil circuit and then turn on the power, press the up button UP ↑, to see whether the motor rotation is correct (lifter has upward lift for the correct. Otherwise, the motor rotates in the reverse direction without oil supply). If the rotation is not correct, first disconnect the power supply to change the phase, the motor rotation is correct, make up oil exhaust adjustment.

2, the tank will be filled with hydraulic oil, in order to ensure that the service life of the hydraulic system and to ensure that the equipment operates in the best state, please fill 46 # quality anti-wear hydraulic oil.

3, Equipment synchronization leveling:
