WO1989012145A1 - Stone tongs for excavators - Google Patents
These stone tongs for excavators solve an old problem, namely that large stones present in the excavated earth cannot be lifted with an ordinary excavator shovel. This problem is solved by the invention by means of two additional gripper arms or tong elements (1) which can be mounted on an ordinary excavator shovel (2) and hydraulically controlled.

Excavator vs. Backhoe: What's the difference?
The excavator moves and functions based on a system of hydraulic fluid moving through hydraulic cylinders and hydraulic motors. Due to the use of hydraulic cylinders, their mode of operation is fundamentally different from older cable-operated excavators which used winches and steel ropes to accomplish the same movements and operation.
