• Besides the physical protection of hydraulic hoses and composite parts, be aware that the lift runners inside the columns are
equipped with nylon slide pads.
• The heat generated by welding can melt or deform the nylon slide pads. Hot metal chips, welding sparks and slag falling inside
the lift columns can damage the nylon pads, the lift runners, and the chain break protection devices.
• ALWAYS LOWER or LIFT the lift runners and the nylon slide pads as far away as possible from the area to be welded.
• ALWAYS use a welding blanket to prevent hot metal chips, welding sparks and slag from falling inside the columns. Clean out the
columns if required.
• The installer or body builder must make sure that the rear frame of the body is sufficiently strong to sustain the forces exerted by the
column lift and its load at the maximum rated capacity, plus legally mandated safety factors.
• ALWAYS grind off the galvanization or paint from the areas to weld.
• The cylinder beam must be strongly connected to the rear cross member of the vehicle floor. Once in use, this connection will prevent
the cylinder beam from bowing down when heavy loads are transferred from the platform to the vehicle floor or vice versa.
• For column lifts with an aluminum cylinder beam, follow the bolt instructions in 7.3 from page 20 onwards. (unless the rear sill of the
loading floor is aluminum too, and both can be welded together).
• Push the columns and the cylinder beam hard against the rear frame of the body (and shims if necessary).
• Make sure the cylinder beam is level and parallel with the rear sill of the vehicle floor.
• Make sure that the lift frame and cylinder beam are properly centered, square, plumb, level, and true to the vehicle body.
• Use suitable C-clamps to secure the lift columns and cylinder beam in the final working position.
