## Abstract

A lifting bale is mounted on top of an injector head for handling the injector head. The lifting bale includes a lifting arm attached to the injector head, an articulated member attached between the injector head and the lifting arm, the articulated member having a knee joint, and a cylinder, having an extendable and retractable arm, attached between the injector head and the knee joint. The cylinder arm is configured to be moved to raise the lifting arm, and is further configured to be extended and retracted to provide load balancing of the injector head.

## Claims

### Claim 1

A method of handling an injector head, the method comprising:
pivotally attaching a lifting arm at a first end to the injector head and at a second end to a lifting cable extending downward from a crane;
attaching an articulated member having a knee joint between the lifting arm and the injector head;
attaching a cylinder having an arm between the injector head and the knee joint;
manipulating the cylinder arm and raising the lifting arm;
positioning the injector head over a wellbore; and
extending or retracting the cylinder arm to balance the injector head.

### Claim 2 (depends on 1)

The method of claim 1, further comprising extending or retracting the cylinder arm as required to vertically align the injector head with the wellbore.

### Claim 3 (depends on 1)

The method of claim 1, wherein the cylinder is hydraulic.

### Claim 4 (depends on 1)

The method of claim 1, wherein the cylinder is electric.

### Claim 5

A method of positioning an injector head over a wellbore, the method comprising:
pivotally attaching a lifting arm at a first end to the injector head and at a second end to a lifting cable extending downward from a crane;
attaching an articulated member having a knee joint between the lifting arm and the injector head;
attaching a cylinder having an arm between the injector head and the knee joint;
retracting the cylinder arm, and thereby raising the lifting arm;
positioning the injector head over the wellbore; and
extending or retracting the cylinder arm to vertically align the injector head with the wellbore.

### Claim 6 (depends on 5)

The method of claim 5, wherein the cylinder is hydraulic.

### Claim 7 (depends on 5)

The method of claim 5, wherein the cylinder is electric.
