Abstract
A motor driven hydraulic tool including a portable battery is preferably employable for a cable laying operation. To displace a movable die toward and away from a stationary die, a piston is driven by pressurized hydraulic oil fed from a hydraulic pump section. The hydraulic pump section is operatively connected to a driving mechanism including a motor via a cam link mechanism. A plunger of the cam link mechanism includes a ring-shaped fitting portion which has an eccentric shaft fitted therein to rotate freely. The eccentric shaft is made integral with the rotational shaft of a motor for the driving mechanism.
