Title:
LIFTING MECHANISM FOR SUPPORTING LEG OF TRAILER
Document Type and Number:
Japanese Patent JPH01111555
Kind Code:
A
Abstract:
PURPOSE:To simplify the lifting operation of a supporting leg by making it possible to oscillate the supporting leg vertically oscillatably supported in the lower part of a trailer by the operation of an operating lever, and determining a direction of the oscillation of the supporting leg according to a disconnected state between the trailer and a tractor. CONSTITUTION:In a trailer connected to a tractor through engaged couplers 4, 5, a supporting leg 18 is fixed to a lower part of the front end of the trailer through a supporting case 19 and oscillatably round a supporting shaft 20, to which ratchet gears 23, 24 are fixed. When a disconnecting lever 12 is rotated into an unlocked state, a claw piece 35 is meshed with the ratchet gear 34 through a rod 41 and a cam 38 to regulate the upward rotation of the supporting leg 18. In this state, a movable claw 30 is clockwise rotated through a rod 27 by pushing a push button 29 of a parking lever 24 functioning as an operating lever to allow the clockwise rotation of the ratchet gear 23. The dead weight of the supporting leg 18 therefore makes it oscillate downward, resulting in an earthed wheel 21.
