Motion Locks for Central Research Laboratories' manipulators are used to lock the manipulator rigidly in any position within the dimensional limits of the manipulator. This allows the manipulator to hold an object in space without requiring an operator, and facilitates the installation and removal of the manipulator.
In general, motion locks come in three distinct units:
The three units can be operated independently, or together (manually or pneumatically actuated.)
The tong/grip lock is a part of all standard manipulator handle assemblies.
