Cable puller
Cable pullers are provided. A cable puller includes a frame, and a boom assembly rotatably connected to the frame. The boom assembly includes a drive assembly, a first arm extending in a first direction from the drive assembly, a second arm extending in a second opposite direction from the drive assembly, and a third arm rotatably connected to the second arm. Rotation of the boom assembly relative to the frame causes rotation of the third arm relative to the second arm to a position wherein a longitudinal axis of the third arm is parallel with a longitudinal axis of the second arm.
1. A cable puller, comprising;
a frame; and
a boom assembly rotatably connected to the frame, the boom assembly comprising a drive assembly, a first arm extending in a first direction from the drive assembly, a second arm extending in a second opposite direction from the drive assembly, a third arm rotatably connected to the second arm, and wherein the drive assembly comprises a handle, the handle rotatably connected to the first arm at a free distal end of the first arm,
wherein rotation of the boom assembly relative to the frame causes rotation of the third arm relative to the second arm to a position wherein a longitudinal axis of the third arm is parallel with a longitudinal axis of the second arm.
2. The cable puller of claim 1 , wherein the boom assembly further comprises a bracket assembly, the bracket assembly rotatably connecting the boom assembly to the frame.
3. The cable puller of claim 2 , wherein the drive assembly comprises a motor, a capstan, and a drive frame, wherein the first arm and the second arm are fixedly connected to the drive frame, and wherein the drive frame is fixedly connected to the bracket assembly.
4. The cable puller of claim 3 , wherein the capstan extends from the drive frame along an axis which is transverse to a longitudinal axis of the first arm.
5. The cable puller of claim 1 , further comprising a channel bracket fixedly connected to a proximal end of the third arm and rotatably coupled to a distal end of the second arm, wherein rotation of the third arm relative to the second arm to the position wherein the longitudinal axis of the third arm is parallel with the longitudinal axis of the second arm causes the channel bracket to fit over at least a portion of the second arm.
6. The cable puller of claim 1 , wherein rotation of the third arm relative to the second arm is limited such that the third arm cannot rotate relative to the second arm past the position wherein the longitudinal axis of the third arm is parallel with the longitudinal axis of the second arm.
7. The cable puller of claim 1 , further comprising a strike plate mounted to the frame.
8. The cable puller of claim 7 , wherein the boom assembly further comprises a fourth arm and a joint assembly rotatably connecting the third arm and the fourth arm, and wherein rotation of the boom assembly relative to the frame causes the joint assembly to contact the strike plate, wherein such contact causes rotation of the third arm relative to the second arm to the position wherein the longitudinal axis of the third arm is parallel with the longitudinal axis of the second arm.
9. The cable puller of claim 1 , wherein the third arm comprises a fixed member and a movable member, the movable member telescopically movable relative to the fixed member.
10. The cable puller of claim 1 , wherein the boom assembly further comprises a fourth arm rotatably connected to the third arm.
11. The cable puller of claim 10 , further comprising a conduit-engagement device rotatably coupled to the fourth arm.
12. The cable puller of claim 11 , wherein the conduit-engagement device comprises a removable insert, wherein the frame defines a slot, and wherein the removable insert is insertable into the slot.
13. A cable puller, comprising;
a frame, the frame comprising a base and a vertical member extending therefrom;
a strike plate mounted to the base; and
a boom assembly rotatably connected to the vertical member, the boom assembly comprising a drive assembly, a first arm extending in a first direction from the drive assembly, a second arm extending in a second opposite direction from the drive assembly, a third arm rotatably connected to the second arm, and a fourth arm rotatably connected to the third arm by a joint assembly,
wherein rotation of the boom assembly relative to the frame causes the joint assembly to contact the strike plate, wherein such contact causes rotation of the third arm relative to the second arm to a position wherein a longitudinal axis of the third arm is parallel with a longitudinal axis of the second arm.
14. The cable puller of claim 13 , wherein the boom assembly further comprises a bracket assembly, the bracket assembly rotatably connecting the boom assembly to the vertical member.
15. The cable puller of claim 14 , wherein the drive assembly comprises a motor, a capstan, and a drive frame, wherein the first arm and the second arm are fixedly connected to the drive frame, and wherein the drive frame is fixedly connected to the bracket assembly.
16. The cable puller of claim 15 , wherein the capstan extends from the drive frame along an axis which is transverse to a longitudinal axis of the first arm.
17. The cable puller of claim 13 , further comprising a channel bracket fixedly connected to a proximal end of the third arm and rotatably coupled to a distal end of the second arm, wherein rotation of the third arm relative to the second arm to the position wherein the longitudinal axis of the third arm is parallel with the longitudinal axis of the second arm causes the channel bracket to fit over at least a portion of the second arm.
18. The cable puller of claim 13 , wherein rotation of the third arm relative to the second arm is limited such that the third arm cannot rotate relative to the second arm past the position wherein the longitudinal axis of the third arm is parallel with the longitudinal axis of the second arm.
19. The cable puller of claim 13 , wherein the third arm comprises a fixed member and a movable member, the movable member telescopically movable relative to the fixed member.
20. A cable puller, comprising;
a frame; and
a boom assembly rotatably connected to the frame, the boom assembly comprising a drive assembly, a first arm extending in a first direction from the drive assembly, a second arm extending in a second opposite direction from the drive assembly, and a third arm rotatably connected to the second arm,
wherein rotation of the boom assembly relative to the frame causes rotation of the third arm relative to the second arm to a position wherein a longitudinal axis of the third arm is parallel with a longitudinal axis of the second arm, and
wherein rotation of the third arm relative to the second arm is limited such that the third arm cannot rotate relative to the second arm past the position wherein the longitudinal axis of the third arm is parallel with the longitudinal axis of the second arm.
21. A cable puller, comprising;
a frame; and
a boom assembly rotatably connected to the frame, the boom assembly comprising a drive assembly, a first arm extending in a first direction from the drive assembly, a second arm extending in a second opposite direction from the drive assembly, a third arm rotatably connected to the second arm, and wherein the drive assembly comprises a handle, the handle connected to the first arm at a free distal end of the first arm,
wherein rotation of the boom assembly relative to the frame causes rotation of the third arm relative to the second arm to a position wherein a longitudinal axis of the third arm is parallel with a longitudinal axis of the second arm.
