Patent attributes
A lifting table includes a top plate height adjustment device that performs a height adjustment of all support columns in a synchronized manner. The top plate is supported on the floor by of a leg structure provided with multiple support columns arranged in parallel. Top plate receiving structures attach a column to the top plate and change the length of the support columns. Push valves exposed on the inside of the top plate receiving structures are actuated, changing the length of gas springs provided inside of the support columns. By extending an operation rod unit into the top plate receiving structures from a single handle of an operation lever via a connection fitting, the push valves are operated the same amount and at the same time in all of the columns with a single operation, so that it is possible to smoothly raise and lower the top plate.
