An engine compartment 6 mounted behind the upper swing structure 2,

A boom 8 mounted on the upper swinging structure 2 and driven by the boom cylinder 7, an arm 10 driven by the arm cylinder 9, and a bucket driven by the bucket cylinder 11. A work device 13 comprising 12,

It is mounted to the upper swing body behind the engine compartment (6), and includes a counterweight (14) in which a weight body such as mercury is embedded so as to maintain equipment balance during operation.

The above fixing means,

Body 18 consisting of a first fixing plate 16 fixed to the outer surface of the upper swing body 2 by a bolt 31, and a second fixing plate 17 extending at right angles to the first fixing plate 16. Wow,

A first tube 21 formed on the second fixing plate 17 such that a pivoting pin 20 fixed to both sides of the elevating foot plate 19 is rotatably coupled thereto;

Locking is formed on the second fixing plate 17, coupled to the locking hole 22 formed on both sides of the elevating scaffold 19 so as to be locked or unlocked, the handle 23 is formed by the T-shaped outer end The pin 24 includes a second tube 25 in which it is built.

The second tube 25 described above,

Washer-shaped compression plate 28 formed on the outer surface of the locking pin 24,

An elastic member 26 that elastically supports the locking pin 24 when pressing the compression plate 28 toward the locking hole 22 to prevent the locking pin 24 from being separated from the second tube 25;

It further includes a ring-shaped stopper 27 formed on the inner side of the second tube 25 to prevent the elastic member 26 (compression coil spring) from being separated from the second tube 25.

The second tube 25 described above,

A first groove 29 formed at an outer end of the second tube 25 and on which the handle 23 is seated upon unlocking of the locking pin 24 from the locking hole 22 of the scaffold 19;

Cut out in the second tube 25 in a direction perpendicular to the first groove 29, the handle 23 is separated from the first groove 29 by the elastic force of the elastic member 26 when rotated 90 degrees ( 23 further includes a second groove 30 to guide the inside of the second tube 25 so that the locking pin 24 is coupled to the locking hole 22 of the footrest 19.

Hereinafter, with reference to the accompanying drawings an example of the use of an excavator equipped with a cab cap riser according to an embodiment of the present invention.

3 (b) and 4 (b) show a state in which the driver unfolds the elevating scaffold 19 installed on the outer side of the upper swing structure 2 to board the cab 5.

The pivoting pins 20 formed on both sides of the elevating scaffold 19 are rotatably coupled to the first tube 21 formed on the second fixing plate 17, respectively, and the locking pins 24 coupled to the second tube 25. Handle 23) is seated in the first groove 29 formed in the second tube (25). At this time, the elastic member 26 is compressed between the stopper 27 formed on the surface of the second tube 25 and the compression plate 28 formed on the locking pin 24.

Therefore, even when the cab cap riser 4 is mounted on the reinforcing frame 3 mounted on the upper swinging structure 2 and the overall mounting height of the cab cap 5 is increased, the user can raise and lower the footrest 19. And through the stepped footrest (4a) formed in the cab cap riser (4) can easily board or get off the cab (5).

3 (a) and 4 (a) is a state in which the lifting step 19 is installed folded on the outer surface of the upper swing (2) in order to minimize interference due to the exposure of the lifting step 19 for driving. .

Using the pivoting pins 20 formed on both sides of the footrest 19 as a center axis, the footrest 19 is folded up toward the outer side of the upper pivot body 2.

At this time, when pulling the handle 23 seated in the first groove 29 of the second tube 25 described above 90 degrees after turning the handle 23, the locking pin by the elastic force of the elastic member 26 Pull 24 into the second tube 25. The end of the locking pin 24 coincides with the locking hole 22 formed at both sides of the footrest 19 by the user. At this time, the handle 23 is seated in the second groove (30).

At this time, since the locking pin 24 is elastically supported by the elastic member 26 which presses the compression plate 28 toward the locking hole 22 of the footrest 19, the locking pin 24 is not shaken while driving. And preventing the locking pin 24 from being separated from the second tube 25.

Therefore, it is possible to minimize the exposure of the elevating footrest 19 from the outer surface of the upper swing body (2). In other words, when the footrest 19 is folded, it reduces from 220 mm to 75 mm, thereby minimizing interference due to the footrest 19 for elevating during driving.

As described above, an excavator equipped with a cab cap riser according to an embodiment of the present invention has the following advantages.

Even when the cab cap riser is mounted between the upper swing structure and the cab cap, the elevator cab can be easily lifted and lifted by the elevating footrest mounted on the upper swing structure to provide convenience and stability to the user.

In addition, it is possible to minimize the interference caused by the footrest when running by forming a foldable scaffold to be installed due to the cab cap riser mounting.
