Definitions
- the equipment includes a crane and cables pendently supporting the spreader from the crane and shortenable and extendable coupling devices associated with the spreader which may be selectively operated to change the effective lengths of at least certain of the cables while independently of the cable-reeling mechanism on the crane.
- a further aspect of the equipment is linear adjustability of each cable with respect to the spreader and the coupling devices.
- a container being lowered under a condition of longitudinal and transverse levelness will tend to wedge within the ships structure and be abraded along its outer vertical surfaces if lowered into the hatch of a container ship having significant list or abnormal trim deviation.
- This problem is amplified by a practice recently adopted in maritime shipment of cargo containers, i.e., the employment of twin spreaders to lower two containers simultaneously into a ships hold.
- a principal object of the present invention is to provide hoisting equipment of more mechanically simple design than at least some of the mechanisms from the prior art.
- Load hoisting equipment as contemplated by this invention comprises in its simplest form a crane, a spreader in pendent relation with the crane, and cables stored on reels in the crane connecting the spreader therewith and providing at least three points of suspension or connection with a frame.
- the first of such points of connection occurs in a vertical plane containing the longitudinal axis of the frame or the spreader.
- the two other points of connection are spaced lengthwise of the frame from the first point but in spaced relation with the vertical plane at opposite sides thereof.
- the reeling mechanism of the crane is constructed for paying out or reeling in the cables at equilinear rates.
- connections of the cables with the spreader at the two latter points be established through longitudinally extendable or shortenable mechanisms for connecting the cables and the spreader, such as hydraulic cylinders, each being attached at one end to a cable and by its other end to the frame.
- Another feature of the invention occurring in a preferred embodiment resides in the provision of a centrally-pivoted rocking beam pivotally attached to, and extending transversely of, the frame at the first point of suspension and supported directly from the crane by two cables which engage the beam near its ends.
- a preferred embodiment includes, as another feature, adjustable terminal mechanism on the spreader for each cable enabling independent linear adjustment of each cable relative to the spreader frame such as needed in the event of cable stretching to establish the neutral or normal level position of the spreader.

- FIGS. 11 and 12 are schematic, longitudinal and end views of an expandable spreader incorporating two master units attached to an elongate type of slave unit along parallel pivotal transverse axes;
- FIG. 13 is a hydraulic diagram illustrative of a system for a spreader comprising a single master unit and a slave unit.
- FIG. 1 illustrates a typical environment in which spreaders according to the present invention are employed.
- This figure depicts a cargo ship 5 at dockside in position to receive or yield up a container 6 supported by a spreader 7.
- the spreader 7 is supported by cables from a hoist vehicle 8 in track relation with a bridge 9 of a cantilever gantry crane 10.
- This spreader as well as the other spreaders shown in the drawing comprises a frame portion which extends during use as a substantially inflexible unit over the top of a conventional cargo container and interlocks with the container, e.g., by latches entering the top comer castings thereof, such as by latches 145, of the spreader l 1 shown in FIG. 11.
- the spreader 7 is illustrated as of the expandable type comprising a lower frame-like, slave pickup unit 11 and two master slave-support units 12 and 14.
- the slave unit 11 comprises a main chassis or frame 15 and a pair of carriages l6, 17 supported by the frame 15 in relatively movable, longitudinally rectilinear guide relation therewith.
- FIG. 2 illustrates a less complicated version of a master unit than, e.g., the master unit 12 of FIG. 5.
- the unit 20 is attached to a slave pickup unit 21 by four clevisand-eye joints 22 of simple design.
- the entire spreader 24 may be of integral design with the units 21, 22 non-separably merged into one another.
- the spreader 24 is supported by three cables 26, 27, 28 which are connected with the spreader in a manner to establish three-point suspension.
- a first point of suspension is established by engagement of cable 26 with the interior surface of a hollow horn 31 of the cable anchoring fixture 32 shown affixed to the frame structure of unit 20.
- the horn 31 defines a passageway for receiving the cable 26 having about 90 degrees curvature as it extends from its outward entrance to an interior opening 34.
- the upper larger end of the horn flares with accelerating curvature to minimize localized bending of the cable during any angular adjustment of the spreader relative to its cables.
- the cable 26 terminates in a clevis 36 secured to an eye-bolt 37 by the pin 38 with the eye-bolt extending through an end wall 39 of the fixture housing which provides a bearing surface for a nut 41 in threaded relation with the bolt. Adjustment of the bolt 37 relative to the end surface 39 shifts the fixture along the length of the cable 26 and results in vertical adjustment thereof along with adjacent portions of the spreader relative to the cable.
- cables 27 and 28 are attached to extendable and shortenable connecting devices, such as doubleacting hydraulic cylinders 45, 46.
- cylinders as used herein means a power cylinder actuator which includes the actual fluid-containing cylinder, the fluid therein, the piston reciprocating within the cylinder, the connecting rod fixed to the piston and extending outwardly of one end of the fluid-containing cylinder and terminating in a bearing (hereinafter known as the rod end), and a bearing at the closed end of the cylinder (known hereinafter as the cylinder end).
- the cylinders may be ordinarily reversibly oriented within a use situs.
- the cylinder ends of the cylinders are connected to the frame of the unit 20 by clevis-and-eye joints 47 which permit limited universal pivotal movement of the cylinders relative to the frame of unit 20.
- an eye appendage 48 of the cylinder 45 may pivot universally about a spherical bearing block through which a clevis pin 51 extends.
- the cylinder 46 may be attached as shown by similar clevis-and-eye connection.
- a cable 55 which collects within a basket 56 mounted on the unit 20 as the spreader is lifted toward the crane carriage 8 contains many wires for energizing the valves, lights, and a motor-pump unit 59 connected with the reservoir tank 61 for maintaining pressure on the supply lines to the various hydraulically-actuated valves or other devices.
- the electrical circuitry for energizing the various electrical devices on the spreader resides within a well developed electrical art and is not deemed to contribute patentable significance to the invention claimed herein since the circuitry required is easily understood and provided by skilled electricians once the sequences in the operation of the hydraulic equipment is understood.
- the double acting cylinders 45, 46 may be selectively or si multaneously operated to effect movements of the spreader about the various axes shown.
- list adjustment is made about an axis MM which extends in the longitudinal direction of the spreader through the horn 31 and through a point H located halfway between the clevises 64,65. Tilting of the spreader about the axis MM occurs when one of the cylinders 45,46 is linearly contracted while the other is linearly expanded an equal amount.
- Trim adjustment is effected by tilting of the spreader and its load about the axis NN and occurs when the cylinders 45,46 are simultaneously extended or contracted to an equal extent in the embodiment shown in FIG. 2.
- the axis NN passes through the cable 26 and the horn 31 along an'interior area 69 of the horn where the cable first engages the horn. At this point the cable and the horn form a hinge joint for trim adjustment.
- the vertical locus of axis NN shifts slightly through an angling range of the spreader as the cable 26 varyingly engages the horn area 69.
- Tilting adjustment is also available along axes P--P and QQ.
- the spreader and its load may be tilted about the axis P-P by linearly contracting or extending the cylinder 46 without adjustment of the cylinder 45.
- tilting adjustment may be made about the axis 0-0 by actuating the cylinder 45 while restraining the cylinder 46 from any linear adjustment.
- the various axes just described with respect to which tilting may be effected pass approximately through a point J within the cable 26 and the horn 31.
- FIGS. 5 and 6 illustrate another embodiment wherein a slave-carrying master unit 12 is supported on four cables 71,72,73,74 depending from the mobile carriage of an overhead crane such as shown in FIG. 1.
- FIG. 1 shows, two of such master units 12,14 are attached to one slave pickup unit 11.
- the master unit 12 is shown as attached to a slave pickup unit which is served by a single master-slave support unit.
- the single master unit is secured, e.g., at four points, to the master unit to eliminate any relative movement between the master and slave units.
- the capability of the master unit 12 for trim and tilt adjustment is substantially similar to but differs slightly from that of the earlier described slave unit to effect a minor difference in the relative locations of the tilting axes.
- the cables 71,72 are normally in fixed adjustment with the rocker beam.
- the point J occurs along the horizontal longitudinal axis M'M of list adjustment.
- Tilting with respect to axes PP' or QQ' occurs freely only if the connection between the beam 78 and the frame 79 permits universal pivotal movement therebetween.
- the beam 78 has pivotal freedom only about axis MM' and trim adjustment then occurs along a transverse axis N'N' located approximately at two thirds the height of the beam 78 and at a higher level than point J.
- the three basic points of suspension then reside at point J and points S and T which occur approximately midway along the length of sheave block anchor pins 84,85, respectively, of sheave blocks 86,87 which include sheaves 81,82, respectively.
- the axis UU of the sheave pins 88,89 in neutral position is approximately in the same plane as the longitudinal list adjustment axis MM (see FIG. 9).
- axis M 'M approximately intersects axis UU at point H.
- Tilt adjustment of the master unit 12 about the axis M'M' involves, in effect, lengthening of one cable 73,74 and shortening of the other without any change of position of the cables relative to the hoist vehicle 8 in the crane bridge. Such movement is accompanied by tilting of the sheave blocks 86,87 about respective pins 84,85. Such shortening and lengthening of the effective cable length is accomplished in unit 12. by operation of hydraulic cylinders 91,92.
- each cylinder 91,92 comprises av cylinder body 93, piston rod 94, a piston 95 and a'clevis cap 96.
- the clevis cap occasionally referred to herein as the cylinder end is joined by a pin 97 to an eye bolt 98.
- the bolt extends through a frame portion 99 of the unit 12 with nuts. 101 establishing a seating relationship of the eye bolt with the frame portion99'.
- the rod end of the cylinder comprises the outer eye'portion of the connecting rod 94 which is joined by a pin 103 to a clevis terminal 1040f the cable 73 or 74.
- the pin 103 extends also through upstanding webs 105,106 of a runner 108 having a plate-likefoot 109 adapting it to slide along the top flange of frame channel 111 or 112'.
- each sheave periphery, the runner 108, and the longitudinal axis of the cylinder and eye bolt assembly associated with the sheave are constructed and arranged within the unit 12' to provide rectilinear alignment of such partsalongthe upper portion of the unit.
- the effective length of cables 73,74 may be changed in two ways.
- Thecables are adjusted in a semipermanent manner by chang* ing the position of the nuts 101 alongthethread of the eye bolts .98to allow the-respective assembly consisting: of the eye bolt, the cylinder 91 or 92, the runner 108,
- the two cylinders 91,92 are operated equilinearly and simultaneously in the same direction to tilt the spreader about the axis N'N' to effect trim adjustment.
- the cylinders 91,92 are operated equilinearly in opposite directions in a manner similar to that explained with respect to the operation of cylinders 45,46 of the earlier described embodiment.
- FIGS. 6 and 10 depict details of the construction of the rocking beam 78.
- a central eye projection 115 apertured along axis MM' is connected with upstanding clevis elements 116,117 of the master unit frame by a clevis pin or bolt 118.
- the eye projection has side walls 121,122 apertured in the horizontal transverse direction of the spreader to support an eye bolt 123 above the axis M-M' and the eye bolt 124 immediately below such axis. Eye bolts 123,124 are in pin connection with clevis terminals 125,126, respectively, of cables 71,72, respectively. As shown in FIG.
- the cables are supported in a 90 turn by curvate walls 127,128.
- the walls 127,128 are preferably grooved along a transverse vertical plane containing the cables 72 to provide circumferential grooves in the outer surfaces of these walls which partially receive the cables 71,72.
- the effective length of cables 71,72 with respect to points of cable engagement with the beam 78 may be changed by linearly adjusting the cable relative to the beam through rotation of the nuts 131,132 to the different points along the threads of bolts 123,124. Such adjustments are made only if necessary to establish the neutral position of the spreader.
- FIGS. 11 and 12 illustrate a spreader comprising two master units 12,14 and a longitudinally extendable slave pickup unit 11.
- the master units are pivotally connected to the slave unit along a pair of transverse axes X X and Y-Y. As shown, the axes X-X and Y-Y are separated along the length of the base frame 15 of the spreader to separate adjacent ends of the units 12,14.
- the pickup unit 11 is provided with columns 141,142,143,144 terminating upwardly in eye elements which are pinned to clevis elements fixed in respective master units to provide relativepivoting between each master unit and the slave unit.
- the slave pickup unit further comprises carriages 16,17'which are supported on the base frame 15 in longitudinally telescoping guide relationship to suitably spaced latches 146 carried on the carriages at opposite ends of the spreader for entering the corner castings of various length cargo containers.
- FIG. 13 identifies the various hydraulically operated units by numerals found in the other figures.
- the symbolism for valves, lines, etc. is in accordance with that sponsored by the American Society of Mechanical Engineers and should be selfexplanatory.
- This diagram is merely exemplary of a hydraulic system which may be used to effect operation of a spreader such as illustrated in FIGS. 6 to 9.
- the motor-pump unit 59 maintains pressure to trim and lift adjusting cylinders 91 and 92 of FIG. 5.
- the cylinders 45,46 of the first described embodiment may be readily substituted in this diagram for cylinders 91,92.
- the crane operator has available certain hydraulic circuitry including the electrically-actuated solenoid valves shown.
- the portion of the hydraulic system carried on the master unit is a pressure source for that portion of the system carried on the slave unit.
- the supply and return lines 151,152 respectively, connect the system portions through quick disconnect couplings 153.
- the hydraulic system can actuate hydraulic motors 155,l56,157,158 which raise and lower a corner guide 159 at each corner of the spreader.
- the system further actuates cylinders 161,162 which are mounted in the opposite ends of the slave unit to actuate through a mechanical linkage system the latches 145. If used on the spreader of FIG. 11, the cylinders 161,162 could be mounted on the carriages 16,17.
- the diagram shows that the cylinders 161,162 are operated simultaneously, whereas the guide motors 154-158 may be operated selectively.
- the spreader of FIGS. 11 and 12 is controlled with respect to trim adjustments by simultaneously lowering or raising in an equilinear manner all cables of one master unit. Minor trim adjustments are possible, if the operator prefers, by simultaneously actuating the hydraulic cylinders 91,92 of one master unit in the same direction. List adjustments of the spreader as a whole are made by actuating cylinder 91 of one master unit along with cylinder 92 of the other master unit to simultaneously effect cable shortening on both Spreaders or cable lengthening on both spreaders of cables associated with the actuated cylinders, i.e., at one side of the spreader. Cylinder 91 of the one spreader and cylinder 92 of the other spreader will always occur on the same transverse side of the spreader.
- List adjustments may be accomplished (l) by using one pair of cylinders including a cylinder 91 from one master unit and cylinder 92 of the other master unit, or (2) by actuating one of such pairs to lengthen respective cables while actuating the remaining pair of cylinders to shorten respective associated cables.
