5) Hydraulic Two Post Car lift:-

• In Hydraulic Two Post Car Lift, a Hydraulic Two post lift consists of two upright columns with four adjustable arms attached to a carriage assembly and two hydraulic cylinders. The power unit delivers hydraulic fluid to the cylinders. Cables installed between the carriages ensure the arms move together and are synchronized.
• The hydraulic fluid pushes the piston up that causes the platform to rise. To move downwards, the valve opens and the fluid is allowed to flow back into the reservoir and is pushed back using the gravitational force of the lift.
• It is mainly used in the vertical transportation of vehicles in various environments such as two-story or three-story auto repair shops, three-dimensional parking lots, car 4S shops, etc., especially for low-rise buildings.
• Car lift, car hydraulic lift, 2 post lift or 2 column lift, a device which mechanically lifts a car up, so that the mechanic can work underneath. Car Ramp, a device which raises a car from the ground for access to its undercarriage.
• Car hydraulic are equipment installed in an automobile that allows for a dynamic adjustment in height of the vehicle. These suspension modifications are often placed in a i.e., a vehicle modified to lower its ground clearance below that of its original design.

5.1) Benefits of Hydraulic Two Post Car Lift:-:-

Two-post parking lifts, including models like TP-270, TP-320, TP-270H, and TP-230H, boast an array of features that differentiate them from other types of parking lifts. Some of these unique features include:

• Single or double telescopic hydraulic cylinders for direct drive
• Laser cutting technique for the entire structure and components
• Preassembled components for effortless installation
• Integrated control box for streamlined wiring
• Adjustable parking heights
• Safety features such as full-range dynamic anti-fall lock slots, emergency stop button, safety key switch controller, hydraulic overload protection, over-height limit switch, and photocell sensor for obstacle detection
• Anti-skid ramp and platform
• Anti-rust smooth powder coating finish.
• The sturdy and durable design of hydraulic lift has made them popular in auto workshops.
• They are economical and have low maintenance. They can be easily installed and operated.
• They are reliable and produce impeccable results that lead to high productivity rates.
• Low maintenance
• No of components is very less
• Very low annual maintenance cost
• Base Free design makes working beneath the vehicle easy.

5.2) How to operate a Two Post Lift?

• Park the vehicle between two posts
• Lift until wheels are off the ground
• Raise the lift to desired working height
• Next release the lock from both side columns
• Always ensure that the lift is in lock position
• Push the button on the power unit raising the arms until the adaptors make contact
• The extension can be used to help reach lifting points and to help level the vehicle
• Use appropriate adaptors for lifting the vehicle
• Finally, remove the arms from vehicle loading points
• Ensure that the vehicle is level & stable on the lift
• Lower the vehicle, first raise it off the lift’s locks
• Position adaptors at the manufacturer’s recommended lifting points
• Ensure the vehicle’s individual axle weight must not exceed half of the lift’s capacity
• Push the manual lever on the power unit until the vehicle is safely down the ground level.

5.4)Hydraulic Lift Maintenance

• The maintenance you’ll need to perform on your hydraulic lift depends upon the model and configuration. Basic maintenance includes monthly visual safety inspections and replacing the hydraulic fluid on an as-needed basis.
• The oil filter and hydraulic oil only need changing once per year. Fittings and hoses require replacement every five years. Read more about hydraulic lift preventative maintenance in our knowledge base.

5.5)Four Post Lift Model

• The 4 post lift can be used in a variety of roles. Perhaps its best-known usage is as a four post car lift. These units are an excellent option for maintenance and repair work on any vehicle ranging from motorcycles to RV’s to tractor-trailers. In this capacity, a four post lift would include a ramp for easy loading and unloading.
• Another widespread use of the 4 post lift includes the assembly and manufacturing industries where the lift suspends a piece of equipment, like, for example, an aero-engine as it goes through its assembly processes. In this example, the engine would be moved from work cell to work cell via an automated guided vehicle (AGV), and the four post lift would elevate the engine with specialized tooling for the technicians to work on it.
• This same example is seen in the power generation manufacturing of diesel engines, where the massive engine is supported by a rotating assembly hanging from the four post lift. In this capacity, technicians can control the rotation to reach any part of the engine for assembly purposes. The energy industry also uses 4 post lifts to assemble turbines vertically.
• Four post lifts also include personnel lifts that bring technicians to heights required to meet their tasks. These lifts can be found in nuclear power plants and are built large enough to take on parts and product for change out processes.
• 4 post lifts are also used in the insurance industry as moveable ceilings for fire testing and other high-risk scenarios that require a resilient platform for testing insurable materials and the optimal height for sprinkler systems.
• Rail assembly is another industry that uses 4 post lifts extensively to test and assemble railcar bogies – also called wheelsets or trucks. In these facilities, 4 post lifts must be built to stand the rigors of heavy industry and stand up to the stresses of an extreme working environment.
• Theatre four post lifts are a staple in the industry to elevate people and props on stage. There can be one or several per stage, usually built to conform to a particular play or musical.
