Two-Post vs Four-Post vs Scissor Lifts: Which Bay Layout Fits You?

The question is really about access

Every lift type lifts a vehicle. What differs is what you can do once it is up — how much of the underside is
reachable, how much floor the machine occupies when it is down, and which vehicles it can physically accept. Work backwards
from the jobs you want to sell.

Two-post lifts: maximum access per square metre

A two-post lift leaves the underside almost completely open, which is why it dominates general mechanical repair. The
trade-off is that the vehicle hangs on four arms, so very long-wheelbase vehicles and anything that needs the wheels to
move freely are awkward. Space requirement is small; access is excellent.

Best for: general repair, brakes, suspension, inspection, tyre service on cars and SUVs.

Four-post lifts: drive-on stability and alignment

A four-post lift puts the vehicle on two runways. Nothing hangs, the wheels stay on their own level, and you can fit
turnplates and slip plates for wheel alignment. The penalty is floor area — a drive-on platform is a large object
— and the runways sit between you and parts of the underside.

Best for: four-wheel alignment, long-wheelbase vans and pickups, vehicle storage, pre-delivery
inspection.

Scissor lifts: an empty bay when you are not using it

A scissor lift is a low platform that sits flat on the floor. Drive over it, raise it, work on it, lower it and the bay
is clear again. That property alone makes it the default for tyre and bodywork shops where the floor is shared with other
tasks. Flush-mounted versions give a genuinely flat floor.

Best for: tyre and wheel work, bodywork and preparation, quick service, any bay that has to do two
jobs.

Single-post lifts: when floor space is the constraint

A single column lifts a full car. It exists for one reason: floor area. Fast-fit bays, tyre shops and mobile service
units use them because a second column simply would not fit.

Best for: high-density fast-fit layouts, mobile units, container workshops.

How to decide in practice

• Write down the five most common jobs in your workshop and the five heaviest vehicles you will accept.
• Measure the bay: ceiling height, available floor, column positions and door swing.
• Eliminate any architecture that physically cannot accept your heaviest vehicle.
• Of what remains, pick the one that gives the best access to the work you sell most of.
