Four post car lifts have many advantages, including its ability to withstand high duty cycles, making it ideal for use in auto assembly plants and repair shops and for applications in other industries that require the day-to-day maintenance of vehicle fleets. Have you ever wondered what is the procedure to lift a vehicle on a four-post lift?

How to select the easiest post lift model for loading

It's easy to be confused about the type of car lift to select for vehicle repair and maintenance activities.

There are two primary types of car lifts; the 2 post car lift and the 4 post lifter.

Two Post Car Lift

The two post car lift is designed to lift vehicles for easy access to the wheels and the motor vehicle's underside. The two posts are made from heavy-duty material consisting of 2 upright pillars with four adjustable supporting arms to evenly support the car when lifted.

The two columns are mounted on a solid surface, and the arms are raised and lowered using a screw mechanism, hydraulic cylinders, chains, or by cable and pulleys.

Due to its small size, the two post car lift is suitable for small commercial garages or personal use. It's also ideal for operation in smaller spaces and are available as portable models.

There are two types of 2-post car lifts, namely;

1. Symmetrical two post car lift

The two columns are parallel to each other, the arm is equal in size, extending out at a similar angle. Symmetrical two post car lifts are easy to identify as their columns directly face each other.

2. Asymmetrical two post car lift

 The two pillars assume varied angles; one can be at 45 degrees while the other can be 90 degrees. 

A potential downside of a two post car lift is that a vehicle can topple on either side and cause injuries or damage to the vehicle if not positioned correctly.  

The four post car lift is designed to lift heavier loads for heavy-duty work cycles, such as larger trucks and heavy machinery. The 4 post car lift can handle more oversized loads compared to the two post car lift due to the additional support. A four post car lift can handle a load capacity ranging from 9,000 lbs to 40 000 lbs and more.

There are two categories of 4 post car lifts:

1. Four Post-commercial-Grade Lifts

The commercial standard four post car lift dimensions can be designed with a custom lifting capacity and is suitable for large-scale automotive activities. Due to its capacity to handle duty work cycles, the commercial lift is fitted with numerous safety measures to protect the operator, such as air release safety locks, cable-breaking ability, and self-locking mechanical capabilities.

2. Four Post Hobby Car Lifts

This category targets customers who want to use a four post car lift in their home garages and use the lift for storage to save on valuable floor space thanks to the adjustable ladder leveling system. The equipment comes with a caster kit, jack tray, and drip pans and can handle a capacity of 9,000 lbs.

Advantages of a Four Post Car Lift - Four Post Car Lift

The four post lift boasts numerous advantages over the two post car lift. They are:

  • It can handle higher load capacity due to its greater stability, allowing for safer operations and fewer injuries to the operator.
  • The four-post car lift can be used with vehicles and machinery across various industries, not just the automotive sector. For example, the airline industry uses the four-post lift to hoist aero engines. The power generation sector uses the lift to support a rotating assembly elevated by the four-post lift.
  • The four-post lift can also include a technician's lift to elevate an individual to the desired height to work on the machinery comfortably.
  • It can be customized for all customer types, from customers working in their home garages to large-scale companies across various industries.

Portable 4 Post Car Lift

Caster kits can transform immobile stands into portable lifts that can be repositioned, relocated and allow for easy repair and cleaning.

You can modify your four-post car lift into a mobile 4 post car lift by using a caster kit. Most often, when you're operating machinery from a four post car lift, you need to connect it to other components that may not be located close to your position.

A portable four post car lift allows you to move the work station to wherever you need it to avoid unnecessary dismounting.

A 4 post car lift with casters can turn your garage or plant into an adaptable shop that accommodates any vehicle from whichever location you need. The portable four post garage lift can be moved outside while still having access to your equipment.

A four post car lift with wheels lets you move machinery quickly without straining your body or incurring injuries if you're a one-person operation.

4. Custom Vertical Assembly Station

This four post lift is used to position technicians at the position as they build turbines. The iris opening lets technicians build the turbine through the exceptional placement around the opening's diameter powered by a hydraulic system.

Lifting and lowering are actualized by four ball screws placed at each column, driven by mechanically synchronized motors. Technician's safety is incorporated through the 48-degree pitched staircase.

Fall safe and limit switches protect operators and machinery from injury and damage.

Handling has successfully customized vertical assembly stations for rotor assembly and vertical assembly.

8. Pit Mounted Four Post Lift for Transformer Assembly

In the past, transformer coil winding assumed a horizontal position, but that has changed in recent years to vertical winding. This scenario presented a challenge because the coils can stand up to 20 feet, making them inaccessible to workers. Handling's four post lift for transformer assembly solved this problem by installing the four post lift system in a pit where technicians could access the coil at whichever height through a unique open-center platform.

Another challenge was the coil winding increased the diameter, so Handling Specialty designed the platform center to adjust as the size increases. The four post lift for transformer assembly handles 20,000 lbs. and is equipped with a smooth self-locking drive.
