Schilling Robotics RigMaster

The RigMaster is a five-function, rate-controlled, heavylift grabber arm that can be mounted on a wide
range of subsea ROVs

Description

It is engineered for the strength needed to withstand the industry’s harsh and repetitive needs
day after day. 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

It is constructed to be reliable in situations that require rugged operation.
The arm’s linear actuators have been life tested under full load for 250,000 cycles
with minimal wear.

The actuators use the latest cap seal technology to minimize leakage, ensuring long life
and minimal maintenance.
Its construction is of primarily titanium for structural strength, light weight, corrosion resistance,
and extraordinary resistance to damage from collisions.

RigMaster manipulators have a proven track record of reliability in the world’s most
demanding subsea environments
