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.

Start with the heaviest vehicle, not the average one

Most two-post lifts are specified on the weight of a typical car, then overloaded the first time a loaded van comes in.
Work out the heaviest vehicle you are realistically willing to accept, add a margin, and specify from that number. A 3.2 t
lift comfortably covers passenger cars, SUVs and MPVs; once vans and light commercials enter the mix, a 4.0 t machine is the
more sensible starting point.

The margin is not just about safety. A machine running near its limit every day wears faster, and you will find yourself
turning work away at exactly the moment the bay is busiest.

Ceiling height decides clear-floor or base-plate

Two-post lifts come in two fundamental layouts:

• Clear-floor — no base frame across the floor, so the bay is completely open. Needs more headroom
  because of the overhead beam.
• Base-plate — a low frame connects the columns at floor level. Works under lower ceilings, but the
  plate gets in the way of tool trolleys and can be a trip hazard.

Measure your actual ceiling with the door open, then subtract the height of the tallest vehicle you will lift plus the
working clearance you want underneath. That figure, not the marketing sheet, is what limits your choice.

Arm geometry: symmetric or asymmetric

Symmetric arms place the vehicle centrally between the columns, which gives an even drive-through and works well for cars
and SUVs. Asymmetric arms offset the vehicle rearwards, which suits vans and pickups whose centre of gravity sits further
back, and makes it easier to open long doors in a tight bay.

If your traffic is mixed, choose asymmetric. If you are almost entirely on passenger cars and want the widest possible
drive-through, symmetric is simpler.

Check the floor before you check the machine

A two-post lift concentrates the entire load on two small base plates. The anchor points need a concrete slab of adequate
thickness and strength — if your floor is thin, cracked or has a suspended section, that has to be solved before the
lift is installed. This is the single most common reason an installation is delayed.

Locks, releases and the small details that matter daily

Mechanical safety locks are standard, but the release mechanism is what your technicians touch every single cycle.
Single-point release from one side saves a walk around the vehicle. Look also at the lifting pad material and whether the
extension adaptors reach the chassis points of the vehicles you actually service.
