Two Post or Scissor Lift for a General Repair Bay

Start With the Building Not the Vehicle

Both lift types cover the same 4 tonne class of vehicle, so capacity rarely settles the question. What settles it is whether you have the headroom for an overhead beam, whether the slab can take anchors, and whether the floor has to stay clear between jobs.

• Low ceiling or roof obstructions rule out a clear floor two post lift
• A protected, thin or rented floor rules out anchoring and excavation
• Bays that double as walkways favour a lift that sits flush when lowered

Where a Two Post Lift Wins

A two post lift gives completely open access under the vehicle, which is what most repair work needs. Within the type there are two further choices. A base floor lift such as the ATL40B carries the load through a floor plate, so there is no overhead beam and no height restriction above the vehicle. A clear floor lift such as the ATL40C moves the connection overhead and leaves the bay floor completely flat for trolleys and drain trays.

• Full wheels-free access for brakes, suspension and exhaust work
• Base floor models suit high-roof vans and low ceilings
• Clear floor models keep the bay floor flat for equipment
• Electric lock versions keep the lowering procedure identical between technicians

Where a Scissor Lift Wins

A scissor lift supports the vehicle on platforms rather than four pads, and the in-ground versions sit almost flush when lowered so the bay stays usable. Several models, including the ASL40/40S and ASL50T, carry a secondary lifting system, which is what makes the same bay usable for wheel alignment.

• In-ground models leave a clear floor between jobs
• Secondary lifting systems give the wheels-free position alignment needs
• Ultra-thin and mid-rise models avoid excavation entirely
• Mobile mid-rise lifts such as the ASL30M need no installation at all

If You Cannot Touch the Floor

Rented premises and protected slabs are the most common reason a workshop cannot install either type in its usual form. Two models answer that directly: the ASL27M has an initial height of 110 mm and needs no trench, and the ASL30M is designed for free installation and can be moved whenever the layout changes.

A Short Decision Path

Work through it in this order and the shortlist usually comes down to two models.

• Do you need alignment in the same bay? If yes, a scissor or four post lift with a secondary lift
• Is there headroom for an overhead beam? If no, base floor two post or scissor
• Can the floor be cut or anchored? If no, trench-free or mobile mid-rise
• Is the heaviest vehicle above 4 tonnes? If yes, move up to the 5 or 8 tonne models
