## Abstract

A cable puller and associated methods are shown. Useful example methods include pipe bursting using cable pullers as shown. Cable pullers and methods shown provide a mechanical advantage that increases an amount of cable pulled in one cycle. Selected examples are shown that include a pulley located on a distal end of a moving portion of an extending and contracting beam. The pulley and the mechanical advantage it supplies helps to improve the efficiency of the cable puller and reduce manufacturing cost of the cable puller.

## Claims

### Claim 1

A cable puller, comprising:
an extending and contracting beam including a first end portion and a second end portion;
a pulley attached at a distal end of the first end portion; and
a single cyclic cable gripper including two gripping jaws, the single cyclic cable gripper attached to the second end portion, wherein the single cyclic cable gripper is configured to pull a cable through a length of pipe by gripping the cable with the gripping jaws on a beam extension, and releasing the cable on a beam contraction.

### Claim 2 (depends on 1)

The cable puller of claim 1, wherein the extending and contracting beam includes a hydraulic cylinder to power the extending and contracting beam.

### Claim 3 (depends on 1)

The cable puller of claim 1, wherein the extending and contracting beam is a hydraulic cylinder.

### Claim 4 (depends on 1)

The cable puller of claim 1, wherein the single cyclic cable gripper is configured to accept side loading of a cable.

### Claim 5 (depends on 4)

The cable puller of claim 4, further including one or more side plates located adjacent to the single cyclic cable gripper.

### Claim 6 (depends on 1)

The cable puller of claim 1, further including a release trigger configured to release the single cyclic cable gripper by bumping one of the two gripping jaws.

### Claim 7 (depends on 1)

The cable puller of claim 1, further including a guide pulley located adjacent to the cable gripping device.

### Claim 8 (depends on 1)

The cable puller of claim 1, further including a reaction plate coupled to the second end portion.

### Claim 9 (depends on 8)

The cable puller of claim 8, further including an angle adjustment pivot located between the soil reaction plate and the extending and contracting beam.

### Claim 10 (depends on 8)

The cable puller of claim 8, wherein the soil reaction plate includes a slot large enough to accept a bursting head.

### Claim 11 (depends on 8)

The cable puller of claim 8, wherein the soil reaction plate includes a vertical and horizontal reaction plate portion.

### Claim 12 (depends on 1)

The cable puller of claim 1, further including a splitter attached to the second end portion before the cable gripper as defined along a cable pulling direction.

### Claim 13 (depends on 12)

The cable puller of claim 12, wherein the splitter is located before the pulley as defined along the cable pulling direction.
