Japanese Patent JP2016088732
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a jack device for a high place work vehicle capable of preventing the damage of a road surface when the jack device is installed, saving troubles for installing a jack base, and preventing the sliding movement of a vehicle when the jack is installed on an inclined surface to carry out high place work.SOLUTION: A jack device for a high place work vehicle includes: a jack portion provided on a vehicle side part and extending in a lower side of a vehicle and a diagonal outside direction; a ground portion provided under the jack portion to ground with a road surface; and a connecting portion which rockably connects the ground portion to the jack portion. The ground portion has a ground surface structure having a hard member with small sliding resistance with the road surface, and an elastic member with larger sliding resistance with the road surface than the hard member. The ground surface structure slides toward the outside of the vehicle on the road surface during the extending action of the jack portion, and fixes the ground portion on the road surface by catching the road surface with the elastic member part, when the jack portion stops the extending action.SELECTED DRAWING: Figure 4
