Abstract
A continuous-operation cargo-transfer equipment. It comprises bulk-cargo uptake mechanisms (4a), an upright conveyor-constituted shaft (4), a boom (5) with a conveyor mounted on it that seesaws up and down on a turntable (6), a gantry (10) that travels back and forth on a pontoon (2), intermediate belts (6b & 6c), and a tender-loading conveyor belt (16) that operates in conjunction with a bulk-goods expulsion spout (17) on a pivoting and displacing beam (12). Such equipment is employed outside ports for transferring bulk cargo from deep-draft ocean-going vessels to shallow-draft tenders. The object is to maintain the cargo-uptake point inside the deep-draft vessel (1) as steady as possible. The equipment is provided with two Counterweights (7 & 15). One counterweight (7) compensates for any listing that occurs when the boom wanders out of position. The other counterweight (15) compensates for any listing that accompanies the sweep of the tender-loading conveyor belt (16). The counterweights are forced by cables (8) into whatever position will counteract the motion of the beam, ensuring the stability of the pontoon.
