Abstract: When handling panel-shaped objects, such as glass panes, a gripping device (4) is used in order to remove the objects from stacks (1, 2), in which the objects are inclined towards the vertical, or to position the objects onto stacks (1, 2), wherein the gripping device allows at least two stacks (1, 2) of objects to be formed on bearing blocks, the stacks (1, 2) differing from each other. The gripping device (4) has at least two grippers which are independent of each other. Suction heads (7) are provided as the grippers of the gripping device (4), the suction heads being pivotal independently of each other into and out of the suction head working position associated with the objects. In the process, gripping device (4) suction heads (7) pivoted out of their operating position are arranged above the stacks (1, 2).

Abstract: The present invention relates to a self-propelled type crane that has outriggers, provided at both ends of the front area and both ends of the rear area of the vehicle body, inclined downward from the top to the outside, thereby helping simply manufacture each outrigger with one cylinder, helps prevent each outrigger from falling down while the crane is operated to lift heavy loads, reduces electrical loss by operating only one of the electric motors and one of the hydraulic pumps when a small amount of power for operation is needed, and increases power output by using both the two electric motors and the two hydraulic pumps when a large amount of power for operation is needed.

Abstract: In a crawler crane of the present invention, a plurality of winches 11-14 for winding wire ropes are disposed on a rotating frame 6 of an upper rotating body 3 in a row in a plane view. A cabin 17 and a power unit 18 are disposed on the front and rear portions of either a right side or a left side of the rotating frame 6 of the upper rotating body 3. A working oil tank 36 of the power unit 18 is disposed between the cabin 17 and a driving section 31-34 of the power unit and in close proximity to a rear surface of the cabin 17. The working oil tank 36 is formed in a size which covers the substantially whole area of the rear surface of the cabin 17. In the crawler crane of the present invention, it is possible to take an anti-sound measure for the cabin to a satisfactory extent without causing cost increase. In the crawler crane of the present invention, moreover, it is possible to improve the transportability because the width of the upper rotating body can be shortened.

First, second, and third control circuits responsive to varied positions of the control are optionally connected to the control to provide first, second, and third sets of control signals each with differing responses to the control in a given position so as to move the components in a manner which mitigates instability or inaccuracy due to the physical acuity of the operator.

Abstract: A boom truck is provided which has optimum operating and transport positions. In the operating position an operator's cab is mounted substantially centrally of the chassis of the boom truck, with the boom above the cab and pivotally mounted to the rear of the cab (over the rear axle) for rotation about a first horizontal axis to provide a lifting force when the boom is pivoted by a hydraulic cylinder or similar linear actuators. In transforming the boom truck to an ease of transport position, the cab is slid on rails to one side of the chassis (preferably in the direction substantially parallel to the axles of the chassis), the support for mounting the pivot for the boom is itself pivoted about a second substantially horizontal axis so that the boom lowers, and ultimately the boom moves to a position next to the cab, with at least part of the boom, and perhaps substantially all of the boom, below the top of the cab.
