  • Wheeled vehicle for stringing a cable
    Patent number: 4643370
    Abstract: A vehicle for stringing cable from a spool. A motor may be used to rotate the spool, and a multibrake system may be used to inhibit the rotation of the spool. The brake system includes a variable, light resistance brake capable of being activated when the vehicle is either moving or parked and includes a nonvariable, strong resistance brake capable of being actuated only when the vehicle's parking brakes are used. When the strong resistance brake is applied and thereafter the motor is used to rotate the spool to take in or pay out cable, the strong resistance brake is automatically disengaged during such rotation and is automatically reapplied when such rotation ceases.
