A door and board lifter is used to temporarily lift and hold a rigid sheet of material, vertically, while it is secured. It is generally used when fitting doors or sheets of plasterboard, which are usually fitted flush to the top of a frame or ceiling, rather than with the floor.
They are often just called door lifters but can also be called plasterboard lifters, drywall lifters, wallboard lifters, or panel lifters. The names given to individual lifters is sometimes a reference to the types of sheet material they are designed to be used with.
The maximum weight lifters can be used with is usually between 60kg and 120kg. Some heavy duty lifters can lift up to 200kg. Most lifters can only raise a sheet by a few centimetres, with some being able to lift as high as 9.5cm (4″).
For lifting sheet material much higher, and for assembling in a wider range of positions, there are mechanised board lifters. These are usually called board lifts or board hoists. They can hold sheets at various angles and can be lifted up to ceiling height.
