The above-mentioned aerial work vehicles have excellent maneuverability, but because they are integrated with moving vehicles such as trucks and cranes, it is impossible to use the vehicle for other purposes, and it is difficult to use when working at heights. This was not reasonable because the vehicle or crane would be tied up. Furthermore, when working, it is necessary to stop the worker in close proximity to the columnar object, which poses problems such as blocking traffic.

(Function) By bending the bending joint of the support arm that has clamps at the top and bottom at right angles, the lower half of the support arm can be placed horizontally, allowing it to be held firmly on the platform of a transport vehicle such as a truck. Have your body grip the clamp at the bottom of the support arm. In this transportation state, the vehicle is positioned so that the clamp on the upper part of the support arm faces the columnar object to be worked on, and the columnar object is clamped with the upper clamp. Therefore, by releasing the lower clamp from the holder on the vehicle and extending the bending joint, the lower clamp also becomes capable of clamping the columnar object. When the columnar object is clamped with the upper and lower clamps, the entire device is stabilized, and the column is raised with the worker on the bucket, and at the same time, the tilting joint is actuated as necessary to secure the columnar object. It is possible to lift a worker on a bucket cart to any position and height.

As shown in FIG. 3, with the bending joint 2 of the support arm 1 bent at right angles, the lower clamp 4b of the lower half part 1b of the support arm is attached to a holder H fixedly attached to the loading platform of a truck T, for example. hold it in place. As a result, the entire device including the column 8 and the bucket 12 is moved to the track T.
It can be transported because it is reliably loaded. In this way, the high-altitude working device is carried to the work site and positioned so that the upper clamp 4a faces the columnar object S to be worked on. Therefore, the columnar object S located between the clamping members 5a and 5b of the upper clamp 4a is removed from the clamping member 5.
The device is fixed to the columnar object S by clamping it with a and 5b.

When the apparatus is to be moved to a truck bed or the like after the work is completed, the above work procedure may be reversed. Also,
When removing the lower clamp 4b from the holder H of the truck loading platform, the upper clamp 4a is fixed to the columnar object S with the extendable upper half 1a of the support arm 1 extended, and the lower clamp 4b is released. By contracting the extendable upper half portion 1a of the support arm, movement from the truck bed becomes relatively easy. Furthermore, by utilizing the telescoping function of the upper half of the support arm 1a, one clamp is in a clamping state, the other clamp is released, and the upper half of the support arm 1a is repeatedly extended and shortened to hold the columnar object S. It is possible to climb or descend on your own.

(Effects of the Invention) As explained above, according to the present invention, an extendable column having a bucket and a rotating device is connected to the upper end of a bendable support arm having upper and lower clamps via a tilting joint. By bending and driving the support arm, it is possible to move the workpiece from a transportation vehicle such as a truck to the columnar object under one's own power. Since it can be moved to any height, the transport vehicle can be released when working at heights, and it also functions usefully even in narrow work sites. By appropriately operating the tilting joint provided on the column, the bucket can be positioned freely within a wide range of space above the fixed location where the support arm is attached to the column, so even if there is a column with an obstacle above it, the bucket can be positioned freely. Applicable. Furthermore, since it is independent from transportation vehicles such as trucks, storage management and handling can be performed easily.
