Put slightly higher with respect to by support frame marginal position.
Further, described a kind of amplitude variation trolley rope skipping prevention device, including pulley and side wheel, its described pulley and side
Wheel, be distributed on carriage frame by bearing connected symmetrical dendrimer, and outside its bearing formed full closeding state, another side wheel parallel to
Support bone frame rotates in the horizontal direction, pulley vertically rotates perpendicular to support frame.
Further, a kind of described amplitude variation trolley rope skipping prevention device, described guide wheel, edge has for by steel wire rope
Groove.
Further, described a kind of amplitude variation trolley rope skipping prevention device, described support frame, by guide wheel edge have for
By the manhole of steel wire rope, separately it is rotated on tower crane by pulley and side wheel and moves in parallel.
Further, described a kind of amplitude variation trolley rope skipping prevention device；Also include the rope skipping preventing being installed on below guide wheel
Device.
The having the beneficial effect that of this programme：1st, a kind of amplitude variation trolley for derrick crane, by using rope skipping prevention device,
To solve guide wheel in running, the potential safety hazard of guide wheel groove jumped out by steel wire rope, the roller in addition putting Skipping-rope device is rotatable,
Reduce hoist cable to the abrasion putting Skipping-rope device, improve safety；2nd, all bearing seals for connecting pulley and side wheel are protected
Shield, preventing itself and air directly contact, preventing and treating its corrosion, thus increasing the service life of amplitude variation trolley.
