The assembly 2 comprising a first arm 8 rotatable on a first fixed pivot 4; a second arm 10 rotatable on a second fixed pivot 6; a third arm 12 pivotably connected to the second arm. A first connecting arm 16 extends between the first arm and the third arm and a second connecting arm 22 extends between the first arm and the second arm. Furthermore, a first counterbalance assembly 40 pivotably connected to an arm of the assembly and a second counterbalance assembly 50 pivotably connected to an arm of the assembly. Movement of the assembly from a retracted to an extended position causes at least a portion of one of the first and second counterbalance assemblies to be raised and at least a portion of the other of the first and second counterbalance assemblies to be lowered. The weight of the first counterbalance assembly is at least partially counterbalanced by the weight of the second counterbalance assembly.
