Devices are safety appliances that keep your hands away from the danger area during operation.
Presence-sensing devices cause the machine to stop working when a body part enters a certain danger field.
Restraints use cables attached to a worker's hands and to a fixed point behind the worker to prevent hands from coming too close to the machinery.
Pullback devices also use cables attached to the operator's hands or arms. During the dangerous part of the operation (when a slide or ram is descending) the worker is forced out of the way.
Safety trip controls are used primarily for emergencies. If a worker falls or trips against a pressure sensitive bar, the machine will stop automatically.
