7) Four post Hydraulic Car lift:-

• Four Post Hydraulic Car Lift , a four post lift is a mechanical lifting system that relies on 4 posts to lift a piece of equipment or vehicle to a specified height to perform work on the product. Free Standing four post lifts are often engineered with large lifting screws at each corner, driven electro-mechanically via the control panel or handheld pendant.
• 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.

7.1) Benefits of Four Post Hydraulic Car Lift:-

The lifting height and table size of the car lifting platform are completely customized according to customer requirements.

★ Adopting high-compact drive hydraulic system, stable lifting and setting anti-overload safety protection device.

★ Adopt double safety device, safe and reliable, novel design, sturdy and durable, strong carrying capacity and so on. .

★ The structure of the car lifting platform is sturdy, the four pivots run synchronously, and the installation and maintenance are convenient.

★ The car lifting platform can be used indoors and outdoors, no foundation pit is needed, and installation is fast.

7.2) Uses of Four Post Hydraulic Car Lift:-

• The load is fully loaded and unloaded, the load of the elevator increases and decreases sharply, and the force of the car is uneven. This is very different from the way that ordinary freight elevators gradually load or unload the load. The structure design of car elevator should be able to adapt to this characteristic;
• There are two control button boxes in the car, the driver can operate the elevator without getting out of the car; the rated load is more than 3 tons, the car area is large enough to carry various small cars; the setting of front and back through doors makes it easy for cars to enter and exit elevator;
• It has a car suitable for carrying cars. The car is the only element that distinguishes the car elevator from other elevators specified in the definition of car elevator, which determines that the internal dimensions of the car elevator should be compatible with the shape of the passenger car.
• According to the new definition standards for economical cars and the “Code for Design of Garages”, the external dimensions and weights of various passenger car design models are determined. Therefore, the car elevator car size should also be determined.
• They are generally customized according to customer needs, but still have to meet the minimum size requirements. After determining the size of the site, feedback to the factory to start production customization. After completion, the factory’s after-sales installer will install it on site. guide.
• 
  The price is extremely high, the price is significantly lower than the car elevator, it is economical and applicable, with a small amount of investment, to achieve the purpose of lifting the car upstairs, suitable for 4S shops, maintenance plants, car sales companies, homes and other places.

7.3) What Kinds of Jobs Can You Perform Using a Four Post Hydraulic Car Lift?

Popular services for this lift are:

• Quick Lube
• Quick Inspection of Issues
• Transmission Service and Muffler Repair

Quick lube service lifts usually have ramps on both ends for a faster and more convenient drive through capability.

• A freestanding four post lift is fixed to the factory floor to increase stability and safety when lifting heavy capacities. A moveable 4 post lift can be transferred from one area to another should the factory floor or assembly line require a redesign.
• Custom four post lifts create an exceptional working experience and require very little maintenance. Capacities and lift heights are all dependent on the 4 post lift’s application requirements.
• Tilt features where two parallel posts lift and lower while the other two remain fixed are also available when requested.
• Options can seriously improve the efficiency of the lift and should be discussed with your technical salesperson. The wide area of access standard with a four post lift allows customers to perform many duties.

7.4) Surface Mount four Post Hydraulic Car Lift:-

Above ground surface mount lifts became popular in the 1970’s. They are mounted completely above the concrete floor. Different lifts have different concrete requirements. Most surface mount lifts require a minimum of 4” depth concrete with a minimum compressive strength of 3000 PSI to support the lift columns and/or anchor bolts (Enthusiast style lifts do not require anchoring, but can still be anchored if desired). Lifts with higher rated capacities can require a minimum of 6” depth of concrete.

Anchor bolts must be torqued to the manufacturer’s specification and checked periodically according to the maintenance guide in the lift’s manual. There are also specifications for the minimum amount of depth the anchor bolt needs to be embedded in the concrete. For example, most 4-post lifts up to 14,000 lb. capacities will require an anchor bolt that is 5.5” length by either ⅝” or ¾” width with a minimum embedment depth of 3.25”. This means once the bolt is torqued to spec, the minimum amount above the floor must be no more than 2.25” to achieve the minimum of 3.25” embedment. Follow the particular lift models manual for exact dimensions.

Ease of installation is one advantage of surface mount lifts. They are also relatively portable (enthusiast models are portable without anchors) and can be relocated in another location in case a business or shop owner decides to move to another location. They also do not have the problem of pollution of the ground water like an in-ground lift, if a hydraulic fluid leak occurs.

A surface mount lift is also easier to maintain or repair because it requires no excavation. Surface mount lifts are also less likely to leak oil into the ground (an environmental concern).

One of the most popular types of surface mounted lifts is the four-post wheel engaging type. It has four posts, two lifting crossrails, each one supporting two drive-on runways. The crossrails are synchronized so that they travel as level and together as possible. To keep the two crossrails moving together, steel cables, chain, synchronized motors or hydraulic circuits are used. The most common synchronization type in the USA is the steel cable.
