The RigMaster™ is a five-function, rate-controlled, heavy-lift grabber arm that can be mounted on a wide range of ROVs. The grabber arm can be used to grasp and lift heavy objects or to anchor the ROV by clamping the gripper around a structural member at the work site. Constructed primarily of aluminum and titanium, this manipulator delivers the power, performance, and reliability required for such demanding work. It has interchangeable Jaw Configurations, a boom function which extends or retracts the gripper by 305mm (12in) for a maximum reach of 1,300mm (51.2in) and a depth rating of 6,500msw. The system's standard four-finger intermeshing gripper can handle bulky objects by opening to 284mm (11.2in).
