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.
