is equipped with a front arm main body 24, and a pair of support arms 25 are protruded from the front arm main body 24.
Rollers 26 are pivotally supported on the support arm 25, and these rollers 261'j are connected to the rails 2 of the reach frame 13.
2', the front arm 23 is movable in the front and rear directions along the reach frame 13.

A bracket 27 is provided on the reach frame 13, and a front arm cylinder 2 is attached to this bracket 27.
The base end of 8 is attached with a pin 29, and the front arm 23 is a 30-piece piston rod with a 2g cylinder for the front arm.
It is connected by a bin 32 to a bracket 31 provided in the
These constitute a front arm actuation mechanism 33.

・ Also, a rubber pad 34 is placed on the lower rear surface of the front arm 23.
is installed interchangeably.

35 is a rear arm, and this rear arm 35 is provided with an arm body 36. A pair of support arms 37 are protruded from the rear arm body 36, and a roller 38 is pivotally supported on the support arms 37. By inserting these rollers 38Vi into the rails 22 of the reach frame 13, the rear arm 35 is movable in the front-rear direction along the reach frame +3.

The reach frame 13 is provided with a bracket 39, and the base end of a rear arm cylinder 40 is attached to this bracket 39 with a pin 41. It is connected to a bracket 43 by a pin 44, and these constitute a rear arm actuation mechanism 45.

Further, a rubber pad 46 is attached to the lower front side of the rear arm 35 so as to be replaceable.

Next, the operation will be explained.

The movement range of the front arm 23 is Ll, and the movement range of the rear arm 35 is Lt.

The front arm 23 is moved rearward by contracting the front arm cylinder 2B, and the rubber pad 34 of the front arm 23 is moved backward.
Press it against the front of the fC baggage person. Then, the cylinder 40 for the rear arm is contracted, the rear arm 35 is moved forward, and its rubber band 46 is pressed against the rear surface of the person carrying the baggage, so that the front arm 23 and the rear arm 35 sandwich the person carrying the baggage from the front and back.

Next, the support 3 is raised by operating the lifting mechanism to lift the person carrying the luggage via the swing frame 5, the reach frame 13, the front arm 23, and the arm 35.

In this state, the swing cylinder B is fully extended and retracted to tilt the swing frame 5 around the swing bin 4, thereby tilting the baggage person.

Furthermore, the reach cylinder 15 is operated to expand and contract to move the reach frame 13 in the front and rear directions, thereby moving the person carrying the baggage back and forth.

By carrying out the above-mentioned operations, cargo handling of long objects is carried out.

As described above, the cargo person can be moved in the longitudinal direction by the operation of the reach cylinder 15, so there is no need to move the vehicle body 2 forward or backward to adjust the longitudinal position when loading or unloading the cargo.

In addition, the front arm 23 is activated by the operation of the swing cylinder g.
And by tilting the rear arm 35, these front arms 2
3 and the rear arm 35 are placed on a sloping ground parallel to a fellow baggage person and can hold this person, making it possible to work on a sloping ground (see Fig. 6).

Effects of the Invention As described above, the present invention provides a support 3 which is provided in the vehicle body 2 and moves up and down on the companion mast device 1, and a swing frame 5 is provided on the support 3 so as to be tiltable. A swing operating mechanism 12 that performs a tilting operation is provided, a reach frame 13 is provided on the swing frame 5 so as to be movable back and forth, and a reach actuator w19 is provided on the swing frame 5 that allows the reach frame 13 to move back and forth. This is because the front arm 23 and the rear arm 35 are provided so as to be movable back and forth, and the reach frame 13 is provided with a front arm actuation mechanism 33 that moves the front arm 23 back and forth, and a rear arm actuation mechanism 45 that moves the rear arm 35 back and forth. , the front arm 23 and rear arm 35 are moved by the front arm actuation mechanism 33 and rear arm actuation mechanism 45 to grasp the baggage A from the front and back, and in this state, the support 3 is raised to lift the person carrying the baggage, and further, The reach actuation mechanism 19 moves the reach frame 13 to move the person carrying the cargo, and the swing actuation mechanism 12 tilts the swing frame 5 to handle the person carrying the cargo.

In this way, by holding the baggage person from the front and back without using a fork, and picking up and placing the baggage, the baggage person and the baggage A can be easily separated.
It is possible to improve the loading efficiency by eliminating the need for square timbers between the containers, and by eliminating the need for auxiliary workers, it is possible to save labor and improve work efficiency.
