Clear Floor or Base Floor Two Post Lift

The Only Real Difference Is the Connection

A two post lift has to link its two columns so they stay synchronised. A base floor lift runs that connection through a plate across the bay floor. A clear floor lift runs it overhead. Everything else about the two designs, including the 4000 kg capacity, the laser cut 5 mm columns and the large base, is shared across the ATL40 range.

Choose Base Floor When Headroom Is Tight

With nothing above the vehicle, a base floor lift such as the ATL40B, ATL40BS or ATL40BA takes high-roof vans and tall vehicles that would foul an overhead beam. The trade-off is the plate crossing the bay floor.

• No height restriction above the vehicle
• Suits low ceilings and roof obstructions
• The floor plate has to be crossed by trolleys and drain trays

Choose Clear Floor When the Bay Floor Matters

With no plate between the columns, a clear floor lift such as the ATL40C, ATL40CS or ATL40CA leaves the bay completely flat. Jacks, drain trays and transmission tables roll straight under the vehicle, and the floor is easier to keep clean.

• Nothing crossing the bay floor
• Easier sweeping and washing down
• Requires enough ceiling height for the overhead beam

Then Choose the Lock Type

Within both families there are three release arrangements, and they change the working procedure more than they change the price.

• Bilateral manual lock (ATL40B, ATL40C): release from either side
• Single side manual lock (ATL40BS, ATL40CS): both columns released from one position
• Electric lock (ATL40BA, ATL40CA): released at the control box, with the 24V safety control box supplied as standard

Safety Lock Engagement

On the base floor models the safety lock works from within 500 mm of the ground, so the vehicle is protected early in the lift rather than only at working height. That is worth confirming on any lift you compare, because the first part of the lift is where a mis-set arm is most likely to show up.
