Estimating the term…
A height access device enables motorized access to the driving station of a tower crane atop a mast formed of superposed mast elements. It includes a lift cabin installed inside the mast of the crane and movable vertically along the mast. The height access devices further includes a working platform positioned above and separably connected to the lift cabin. A coupling device provides a non-permanent connection of the working platform to the lift cabin and immobilizes the working platform relative to the mast at a required height. The height access device enables the crane driver to ascend and descend with the lift cabin alone when disconnected from the working platform and with the lift cabin and working platform together, particularly during the assembly and dismantling of the mast.
A motorized height access device for tower cranes that include a mast, the motorized height access device comprising:
A method of assembling and dismantling a tower crane that includes a mast formed by the superpostion of mast elements through the use of a motorized height access device, said method comprising:
A motorized height access device for tower cranes, the motorized height access device including a lift cabin that is installed inside the mast of the crane and that is movable vertically along this mast, the lift cabin being surmounted by a working platform with a guard rail, wherein the working platform is separably connected to the lift cabin, a coupling device being provided for non-permanent connection of the working platform to the lift cabin and for immobilizing the working platform relative to the mast of the crane at a required height, so as to enable use of the lift cabin separated from the working platform, and therefore on its own, for height access.
