Abstract

A work machine includes: a body including: a body frame; a driver's seat at a central portion of the body; a power source at a back portion of the body; and a front-wheel unit disposed at a front portion of the body and extending in a left-right direction of the body, wherein the body has a forward portion provided with at least one first holder configured to hold a rope and/or allowing the rope to pass therethrough. The forward portion is provided with two or more first holders which are each usable as an independent holder or which are usable in conjunction with each other to allow a rope to pass through both holders.

Claims (55)

1 . A work machine, comprising:

a body including:

a body frame;

a driver's seat at a central portion of the body;

a power source at a back portion of the body;

a front-wheel unit disposed at a front portion of the body and extending in a left-right direction of the body, wherein

the body has a forward portion provided with at least one first holder configured to hold a rope and/or allowing the rope to pass therethrough;

the at least one first holder is at a height close to a center of gravity of the power source; and

the center of gravity of the power source aligns in a horizontal plane with a top of a rear wheel at the back portion of the body.

2 . The work machine according to claim 1 , wherein

the front-wheel unit includes:

a left front wheel;

a right front wheel; and

a support frame supporting the front wheels, wherein

the at least one first holder is on a top face of the support frame.

3 . The work machine according to claim 1 , wherein

the at least one first holder is in a U shape.

4 . The work machine according to claim 1 , wherein

the at least one first holder includes two first holders disposed at respective left and right portions of the body and to respective opposite lateral sides of the driver's seat in a front view.

5 . The work machine according to claim 4 , further comprising:

a left front wheel at the front portion of the body; and

a right front wheel at the front portion of the body, wherein

the first holders are within a first width in a front view, the first width being a dimension extending in the left-right direction of the body and defined by respective sides of the front wheels which sides face the center of the body.

6 . The work machine according to claim 4 , further comprising:

a left rear wheel at the back portion of the body; and

a right rear wheel at the back portion of the body, wherein

the first holders are within a second width in a front view, the second width being a dimension extending in the left-right direction of the body and defined by the rear wheels.

7 . The work machine according to claim 1 , wherein

the at least one first holder is below a seat surface of the driver's seat.

8 . The work machine according to claim 7 , further comprising:

a left rear wheel at the back portion of the body; and

a right rear wheel at the back portion of the body, wherein

the at least one first holder has an upper end below respective upper ends of the rear wheels.

9 . The work machine according to claim 7 , wherein

the at least one first holder is at a height close to a height of a step forward of the driver's seat in a front view.

10 . The work machine according to claim 3 , wherein

the at least one first holder includes two first holders disposed at respective left and right portions of the body and each having an opening axis angled relative to a front-back direction of the body.

11 . The work machine according to claim 2 , wherein

the at least one first holder includes two first holders disposed at respective left and right portions of the body,

the support frame includes:

a linear portion fixed to the body frame;

a left extension; and

a right extension,

the extensions extending from respective opposite ends of the linear portion, bent obliquely forward, and supporting the respective front wheels, and

the at least one first holder includes a left first holder on the left extension and a right first holder on the right extension.

12 . The work machine according to claim 1 , wherein

the body has a backward portion provided with at least one second holder configured to hold a rope and/or allowing the rope to pass therethrough.

13 . The work machine according to claim 12 , further comprising:

a bumper extending backward relative to the body, wherein

the at least one second holder includes two second holders disposed at respective left and right portions of the body and forward of and to respective opposite lateral sides of the bumper.

14 . The work machine according to claim 13 , wherein

the at least one first holder includes two first holders disposed at respective left and right portions of the body, and

a third width is larger than a fourth width in a plan view, the third width being a dimension extending in the left-right direction of the body and defined by the first holders, the fourth width being a dimension extending in the left-right direction of the body and defined by the second holders.

15 . The work machine according to claim 1 , further comprising:

a lock mechanism configured to restrict swing of the front-wheel unit relative to the body frame.
