Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a man-1-lorry complete crane.

[Prior art]

When transporting cargo such as a container with a man trolley type crane, as shown in Fig. 5, in order to block the view E of the operator in the operator's cab 2 of the top tier cargo C1 or the man 1 to the trolley crane 1. During the r-grip or r-release operation of the load, the load C2 located in the shadow of the load C4 or the hanging tool 3 that is ready to hang the load C2 may not be visible from the driver's cab 2.

In particular, in the conventional man trolley type crane 1, the operator's cab 2 is fixed to the trolley 4 and its position cannot be changed, so if the above situation occurs, the efficiency of cargo transportation work will be significantly reduced.

[Purpose of the invention]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to improve the efficiency of cargo transportation work using a man trolley type crane by configuring the operator's cab of the man trolley type crane so that it is not obstructed by obstacles.

[Structure of the invention]

That is, the present invention is a crane having a movable trolley, which is characterized in that a driver's cab is movably attached to the trolley, and the orientation of operating equipment in the driver's cab can be changed.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view of the man trolley type crane according to the present invention, and the crane body 15 of the man trolley type crane IO is no different from conventionally known crane bodies.

That is, the crane main body 15 has two gate-shaped structures 16 at the front and rear, and these structures 16, 16 are connected together at the lower part near the wheels 17 by a connecting structure (not shown).

The wheels 17 are pneumatic tires, and are configured to be able to run on the road surface 20 in the front and rear directions relative to the plane of the paper.

Then, as shown in FIG. 3, rails 19 are laid on the tops of the beams 18 of each gate-shaped structure 16, and the trolley 14 runs on these two rails 19.

Two rails 22.22 for moving the driver's cab are provided below the trolley 14, and the driver's cab 12 is placed on these rails 22.22.
be arranged so that it can be run. The driver's cab 12 is equipped with wheels 23 and is movable, but normally stands still on the left side of the rail 22, as shown in FIG. Each of the above rails 22
is fixed by an arm 21, as shown in FIGS. 1 and 2.

The driver's cab 12 is equipped with a number of windows 24 around the perimeter, providing good visibility, but as shown in FIG. 27
It is configured so that it can rotate 180 degrees.

Further, the wires Y1 to Y4 for raising and lowering the hanger 13 are installed outside the passage of the driver's cab 12 so as not to obstruct the movement of the driver's cab 12.

Here, the reference numeral 30 is a winding drum provided on the trolley 14;
Reference numeral 33 indicates a pulley provided on the hanging tool 13.

Next, the cargo C2 carried by the man trolley type crane 10 is
This section explains the lifting work.

As shown in FIG. 1, when lowering the hoist 13 from the trolley 14 of the man trolley type crane 10 directly above the load C2, as shown by the solid line, the driver's cab 12 is placed on the moving rail 2.
2, the field of view E1 may be obstructed by the topmost luggage C1.

At that time, the driver's cab 12 is moved to the right side of the moving rail 22, as shown by the two-dot broken line.

45, when the floor 17 of the driver's cab 12 is rotated 180 degrees in the direction shown by the arrow A, the operating device 25 and the seat 26 are moved together with the floor 17 by 180 degrees in the direction shown by the arrow A. Rotate.

Then, as shown in FIG. 1, the field of view from the driver's cab 12 becomes as indicated by the symbol E2, and it becomes possible to work while completely monitoring the cargo C2 and the hanging equipment 13 without being obstructed by the cargo C7. .

Further, when the driver's cab 12 returns to its original position as shown by the solid line in FIG. 1, the operating device 25 and seat 26 are rotated in the direction of arrow B together with the floor 27.

〔Effect of the invention〕

2, the present invention provides a crane having a movable trolley, in which the operator's cab is movably attached to the trolley and the orientation of the operating equipment inside the operator's cab can be changed, thereby preventing obstacles. The field of vision in the operator's cab is no longer obstructed by objects, and the efficiency of cargo transport work using the man trolley crane is greatly improved.

In the above explanation, we have explained the trackless man trolley type crane, but the track type man trolley type crane,
It is also effective for bridge type cranes in container yards, ship gantry cranes, etc.
