Jacks are provided to immobilize and level the support base at a desired location. A platform assembly is secured over the support base on extendable supports. Braces are secured between the support base and the platform assembly and are extendable with the movement of the platform assembly over the base whereby to maintain the platform assembly substantially stable during its displacement and at a stationary desired working elevation with respect to the support base. A displaceable worker support platform is secured to the platform assembly for supporting workers thereon.
