Abstract
A load gripping hand cart includes a wheel supported frame with a projectionless load abutment surface that can be positioned adjacent to one side of an elongated load. Arms are selectively pivoted on the frame by a manually operated actuator mechanism to converge against sides of the load and secure it to the load abutment surface. The actuator mechanism includes self-locking features that facilitate locking of the arms against the load in a closed orientation. The actuator mechanism is situated separate from the handle end of the cart frame so the load can be secured to the cart frame and so the arms can be locked in an operation separate and independent from the lifting and transport operation which is controlled from the handle end of the frame.
