Tiltable cab assembly
A cab assembly is disclosed for use with a machine having a frame. The cab assembly may include an operator cab with a first side and a second side, a plurality of cab mounts connecting the operator cab to the frame, and a hydraulic cylinder connected at one end to the operator cab and at an opposing end to the frame. The plurality of cab mounts may be selectively disconnected from the operator cab to allow the hydraulic cylinder to tilt the operator cab toward the first side or the second side of the operator cab.
1. A cab assembly for a machine having a frame, comprising:
an operator cab with a first side and a second side;
a plurality of cab mounts connecting the operator cab to the frame;
a hydraulic cylinder connected at one end to the operator cab and at an opposing end to the frame, wherein the plurality of cab mounts may be selectively disconnected from the operator cab to allow the hydraulic cylinder to tilt the operator cab toward one of the first side and the second side of the operator cab; and
a lock bar configured to secure the operator cab in a tilted position, wherein the lock bar includes a stowed position in which opposing ends of the lock bar are both secured to the frame.
2. The cab assembly of claim 1 , wherein the plurality of cab mounts includes four cab mounts positioned at corners of the operator cab.
3. The cab assembly of claim 1 , further including a plurality of retaining pins configured to removably connect the operator cab to the frame at the plurality of cab mounts.
4. The cab assembly of claim 3 , wherein each of the plurality of retaining pins includes a protrusion at one end.
5. The cab assembly of claim 3 , further including a plurality of linchpins configured to secure the retaining pins at the plurality of cab mounts.
6. The cab assembly of claim 1 , wherein the hydraulic cylinder is generally positioned at a lateral and lengthwise center of the operating cab.
7. The cab assembly of claim 1 , wherein an extension of the hydraulic cylinder tilts the operator cab to an angle of about 35-45° relative to the frame.
8. The cab assembly of claim 1 , wherein opposing ends of the lock bar are selectively connectable one at a time to the plurality of cab mounts to secure the cab assembly.
9. A cab assembly, comprising:
an operator cab;
a frame;
a plurality of cab mounts connecting the operator cab to the frame;
a hydraulic cylinder connected at one end to the operator cab and an opposing end to the frame, wherein the plurality of cab mounts may be selectively disconnected from the operator cab to allow the hydraulic cylinder to tilt the operator cab relative to the frame toward one of the first side and the second side of the operator cab; and
a lock bar selectively connectable between the frame and the plurality of cab mounts to secure the operator cab in a tilted position, wherein the lock bar includes a stowed position in which opposing ends of the lock bar are both secured to the frame.
10. The cab assembly of claim 9 , wherein the plurality of cab mounts includes four cab mounts positioned at corners of the operator cab.
11. The cab assembly of claim 9 , further including a plurality of retaining pins configured to removably connect the operator cab to the frame at the plurality of cab mounts.
12. The cab assembly of claim 11 , wherein each of the plurality of retaining pins includes a protrusion at one end.
13. The cab assembly of claim 11 , further including a plurality of linchpins configured to secure the retaining pins at the plurality of cab mounts.
14. The cab assembly of claim 9 , wherein the hydraulic cylinder is generally positioned at a late al and lengthwise center of the operating cab.
15. The cab assembly of claim 9 , wherein an extension of the hydraulic cylinder tilts the operator cab to an angle of about 35-45° relative to the frame.
16. The cab assembly of claim 9 , wherein opposing ends of the lock bar are selectively connectable one at a time to the plurality of cab mounts to secure the cab assembly.
17. A ballast regulator, comprising:
a frame;
a plurality of wheels configured to support the frame on a railway track;
an operator cab with a first side and a second side;
a plurality of cab mounts connecting the operator cab to the frame;
a hydraulic cylinder connected at one end to the operator cab and at an opposing end to the frame, wherein the plurality of cab mounts may be selectively disconnected from the operator cab to allow the hydraulic cylinder to tilt the operator cab toward one of the first side and the second side of the operator cab; and
a lock bar selectively connectable between the frame and the plurality of cab mounts to secure the operator cab in a tilted position, wherein the lock bar includes a stowed position in which opposing ends of the lock bar are both secured to the frame.
