Abstract
A lifting device for handling flat racks or containers fitted with ISO corner castings comprising a main support plate having a lifting pin projecting from one face for engagement in an end aperture in an ISO corner casting and a tubular support on the plate carrying a locking pin movable in a direction at right angles to the longitudinal axis of the lifting pin for connection in a further aperture in the side of the corner casting for holding the lifting pin firmly in the end aperture, a pivotal link on the plate for connecting it to a lift strap, and to a spreader bar. The invention preferably also incorporates a special device for varying the effective length of the lifting strap.
Claims12
A lifting device for handling flat racks or containers fitted with ISO corner castings comprising a first support plate;
- a lifting pin having a longitudinal axis extending normally to the support plate for engagement in an end aperture in an ISO corner casting on the flat rack;
- means for connecting said plate to a lift strap;
- support on said plate;
- and a locking pin carried by said support means and radially movable along an axis at right angles to the longitudinal axis of the lifting pin for engagement with and disengagement from an aperture in the side of said ISO corner casting.
A lifting device for ISO corner castings comprising:
- a first support plate;
- a lifting pin having a longitudinal axis perpendicular to the support plate for engaging an end aperture in an ISO corner casting;
- means for connecting said plate to a lift strap;
- support means on said plate;
- a locking pin carried by said support means and movable in a direction perpendicular to the longitudinal axis of the lifting pin;
- and
- spring loaded detent means for maintaining said locking pin in an engaged position;
- and in which said locking pin comprises a radially extending locking handle.
A lifting device for ISO corner castings comprising:
- a first support plate;
- a lifting pin having a longitudinal axis perpendicular to the support plate for engaging an end aperture in an ISO corner casting;
- means for connecting said plate to a lift strap;
- support means on said plate;
- a locking pin carried by said support means and movable in a direction perpendicular to the longitudinal axis of the lifting pin;
