The majority of hydraulic lift tables have one set of scissor legs installed in a lower frame with an upper platform. Tandem hydraulic lift tables have 2 or more sets of scissor leg sets installed end to end in a common lower frame under a common upper platform.

Excessively extending the platform length over one single scissor leg assembly could create a teeter totter effect resulting in an unstable load; multiple scissor legs under a common platform spread the load out over the length of the platform improving the overall load stability.

The primary purpose of a tandem hydraulic lift table is to lift, lower or support longer loads. Common applications are to lift, lower or support longer lengths of lumber, steel or plastic pipe during the manufacturing process.

Tandem lift tables can also be used as an adjustable height work platform during the assembly of long equipment or machinery. For example a tandem lift table platform provides a continuous elevated walk way enabling assemblers quick and easy access the area that they are working on during the assembly of over the road trailers, modular homes, recreational vehicles etc.

Tandem lift tables are also used as adjustable height work platforms that are positioned beside a moving production line. For example at an automotive assembly plant a tandem lift table enables an elevated assembler to walk along at the same pace as the moving automobile during upper vehicle inspection or when installing a sun roof, roof racks etc.

Tandem lift tables that are used as an adjustable work height platform are often equipped with a checker plate deck surface for improved traction, 42” high guard rails c/w a mid-rail and 4” high kick plate and access chains or an interlocked gate for employee entrance/exit to the platform.

For ease of operator access it is also common for the lift tables up and down push button controls to be installed on a post on the platform with a secondary lowering control valve installed on the power unit located at the floor level. The secondary lowering valve allows personnel at floor level to lower the elevated platform in the case of a power failure or in the event of an emergency on an elevated platform.
