What Are the Advantages of 2-Pillar Hydraulic Car Lifting? 

Small space occupation: Compared to four column elevators, 2-column hydraulic car elevators have a more compact structure, with two columns occupying a smaller area. In places with limited space, such as internal passages in small buildings and small warehouses, they have more advantages.

Easy installation: Due to its relatively simple structure, the installation process is relatively easy. It does not require complex basic engineering and a large number of installation components, which can save installation time and cost. For example, in some existing buildings, a 2-pillar hydraulic car elevator is more likely to meet the site conditions for later installation.

Smooth operation: The hydraulic system drive can enable the elevator car to achieve smooth lifting and lowering movements. By adjusting the flow rate and pressure of hydraulic oil reasonably, the speed of the elevator car can be precisely controlled, and the impact can be reduced during the starting and stopping process, providing passengers or cargo with a comfortable and safe transportation experience.

 

Structural Composition of 2 Pillar Car Lift 

 

Column

 

The two pillars are the main supporting structure of the double pillar car lift. Columns are usually made of high-strength steel, such as high-quality carbon structural steel or alloy structural steel, to ensure sufficient strength and stability. The common cross-sectional shapes of columns are rectangular or square, with tracks or slides inside for the up and down sliding of the lifting arm. The bottom of the column is usually firmly fixed to the ground with anchor bolts to bear the weight of the car and prevent the 2 pillar car lift from tipping over.

 

Lifting arm

 

The lifting arm is a component that comes into direct contact with the car and lifts it up. The shape and structure of the lifting arm vary depending on the model and purpose of the 2 pillar car lift, but generally have adjustable functions to adapt to the chassis structure of different vehicle models. Lifting arms are usually made of high-strength alloy steel, and some lifting arms are also equipped with rubber pads or special fixtures to protect the car chassis and ensure a secure connection.

 

Hydraulic system (taking hydraulic as an example)

 

Oil pump: It is the power source of hydraulic systems, commonly including gear pumps, vane pumps, etc. The oil pump extracts hydraulic oil from the oil tank and delivers it to the cylinder through the pressure oil pipe. For example, gear pumps have a simple structure and low cost, making them suitable for some small or medium-sized 2 pillar car lifts; Vane pumps have the characteristics of uniform flow and stable pressure, and are widely used in high-performance 2 pillar car lifts.

 

Oil cylinder: It is a key component for achieving lifting action. There are pistons and seals inside the oil cylinder. When hydraulic oil enters the cylinder, the piston moves upward under the pressure of the hydraulic oil, thereby driving the lifting arm to rise. The sealing performance of the oil cylinder is very important. Good sealing can prevent hydraulic oil leakage and ensure the normal operation of the 2 pillar car lift.

 

Control valve: used to control the flow direction, flow rate, and pressure of hydraulic oil. Mainly including one-way valves, overflow valves, and throttle valves. The one-way valve ensures that hydraulic oil can only flow in one direction, ensuring the stability of the 2 pillar car lift when it rises; Overflow valve is used to limit the maximum pressure of the system and prevent system overload; The throttle valve can adjust the rising and falling speed of the lifting arm.

 

Oil pipes and oil tanks: Oil pipes are used to connect various components of the hydraulic system, allowing hydraulic oil to circulate within the system. The oil tank is used to store hydraulic oil and also plays a role in dissipating heat and settling impurities. The capacity of the fuel tank depends on the specifications of the 2 pillar car lift and the requirements of the hydraulic system. Generally, it is necessary to ensure sufficient hydraulic oil to complete the lifting action.

 

Inspection of hydraulic components for 2 post hydraulic car lift 

 

Oil pump maintenance: Regularly check the working status of the oil pump. Check if there is any leakage at the inlet and outlet of the oil pump, and if there is any abnormal noise during operation. If a leak is found in the oil pump, it is necessary to promptly check whether the sealing components are damaged and replace them. For abnormal noise, it may be due to wear of components such as gears, blades, or plungers inside the oil pump, which require repair or replacement.

 

Oil cylinder inspection: Check the sealing of the oil cylinder and inspect the surface of the cylinder body for oil stains. If oil stains are found, it may be due to damaged piston seals and need to be replaced in a timely manner. At the same time, check whether the piston rod of the oil cylinder is scratched, bent, etc. If it is damaged, it should be repaired or replaced in a timely manner.

 

Control valve inspection: Check the working status of various control valves, such as check valves, relief valves, and throttle valves. Ensure that the valve operates flexibly without any jamming. It is possible to determine whether the control valve is working properly by testing the system pressure and flow rate. For example, check whether the set pressure of the overflow valve is accurate and whether the throttle valve can effectively regulate the lifting speed of the car.
