摘要： PURPOSE: To make compact a mobile crane in size in a force-and-rear direction by a method wherein two retaining arms are erected on a rotary rim, provided rotatably at a center between fore and rear wheels on a body frame, while the base part of a crane mast is supported swingably between both retaining arms. CONSTITUTION: Lateral beams 2, 3, contractable in the widthwise direction of a vehicle, are provided at both end parts 1a, 1b of a box type vehicle frame 1 or a crane retaining body while wheels 5, 6, supported at respective positions of fore-and-rear and left-and-right through spring legs, are fixed through bearings. Supporting legs 4, movable into the vertical direction, are provided on the tip end parts of respective lateral beams 2, 3 so as to be contacted freely with the earth. On the other hand, a rotary rim 8, rotatable about and axial line 8a, is arranged on the retaining body 1 at the center between the fore-and-rear wheels 5, 6 both retaining arms 9 are erected in parallel with an interval on the rotary rim 8 while a telescope crane mast 11 is supported swingably about an axial line 10 on the horizontal crane section of both retaining arms 9 and an operating cabin 15 is arranged on the rotary rim 8.
