A wire rope or cable stabilizing system for applying a balancing force to a suspended load to maintain vertical movement of the load perpendicular to the surface upon which the load is to be placed. The balancing force is effected to balance the lateral loading forces which may be applied to the suspended load such as may be due to, for example, the list or trim of a vessel, or the wind loading forces encountered when removing or replacing a hatch cover during a loading or unloading operation of a ship.

Suspended load positioning stabilizing system

A straddle-type mobile hoist having loading slings operatively connected to automatically equalize the loading applied through the slings and adapted to vary the lateral spacing between slings.

Mobile hoist

A straddle carrier consisting of an inverted U-shaped frame, having a pair of vertically extending legs that define an elongated container carrying bay with each leg supported by a plurality of wheels is disclosed herein. First and second engines are respectively supported on the legs and each engine drives a plurality of pumps which supply pressurized fluid for driving and steering the vehicle, as well as pumps for supplying fluid to a plurality of other functions. The hydraulic circuit for performing the plurality of other functions as well as the steering function is designed so that all of the functions may be operated from the pumps driven by one of the engines in case of power failure in the other engine.

Straddle carriers for containers

A hoisting mechanism for a spreader of a straddle carrier is disclosed herein. The hoisting mechanism includes two fluid rams respectively located at diagonal corners of a generally inverted U-shaped frame. One fluid ram is connected to one end of the spreader through three parallel flexible members with the intermediate flexible member connected to one corner of the spreader and the two outer flexible members are connected to the opposite corner of the spreader. The disclosure also shows a unique steering linkage for steering all eight wheels that support the straddle carrier.
