PONT ELEVATEUR 4 COLONNES
PE 4101T
CHEMIN PLAT OSCILLANT 400V 5T
Installation and principle of safety strip
The hanger plate 5 is suspended in the post, and has a screw at the upper end thereof, and can be
adjusted up and down by adjusting the nut; the hook 4 is hinged in the cross beam, and enters
the hole of the hanger plate under the pulling force of the spring 8. When the work platform rises,
the hook also rises along with the cross beam; when the hook rises to the required height, lower
the work platform slightly so that the hook can be supported in the rectangular hole of the hanger
plate to ensure that the work platform is safely at the required height during the repair. At this
time, the hanger plate bears the weight of the work platform and the vehicle, and the wire rope is
not loaded temporarily for the purpose of safe operation.
To lower the work platform, fi rst press the UP button to raise the work platform slightly, then turn
the safety handle on the longitudinal beam clockwise (and lock the handle), and pull the hook
off the hanger plate by the pull rod 7. Then press the lowering handle on the pump station, open
the oil return passage to drain oil from the cylinder, and then the work platform will be lowered
under the action of gravity. Please note that if the work platform is lowered to a certain height and
other repairs are required, it is still necessary to support the hook in the hole of the hanger plate
to ensure safety.
The eccentric wheel 2 is hinged on the cross beam, and the roller 1 rests on the wire rope 3
under the tensile force of the spring 6. During the operation, the roller moves up and down along
the tensioned wire rope to maintain a certain gap between the eccentric wheel and the hanger
plate. When the wire rope breaks, the roller loses its support, and the eccentric wheel 2 rotates
rapidly under the tensile force of the spring to lock the cross beam on the hanger plate, eff ectively
preventing the work platform from falling.
