Adjacent both ends of the beam there are provided upstanding pairs of parallel plates 12 and to each pair there are adjustably bolted the upper ends of struts 13 which are upwardly convergent from the ends of a beam support 14 spaced transversely below the beam. Adjacent both ends of the beam 10 are attachment lugs 15 apertured for connection to lifting chains 16 which are provided at their upper ends with means (not shown) for connection to a crane or other cargo lifting gear.
  • the beam may be supported on the cargo by its supports 14 and/or the end plates 11.
  • the top of the beam 10 is provided with two saddles 17 arranged to receive the arms of a fork-lift vehicle.
  • the underside of the beam 10 is provided with pairs of spaced retaining blocks 18 and 19 which are coaxially aperture ' d.
  • a temporary holding plunger 20 is slidable, and in each of the blocks 19 a sling locking plunger 21 is slidable.
  • Each temporary holding plunger 20 may be slidably advanced from its block 18 to enter the aperture of the other block 19 and likewise each sling holding plunger 21 may be advanced from its block 19 to enter the aperture of the block 18.
  • each temporary holding plunger 20 may be held releasably in either its advanced position or (as shown in FIG. 3) its retracted position in its block 18 by a spring-loaded ball 22 within the block engaging in either one of two recesses 23 in the retaining plunger, the two recesses being connected by a shallower groove 24.
  • the retaining plunger may be pushed from its retracted to its advanced position manually, and from its advanced to its retracted position by an advancing plungers 21.
  • the plungers 21 are interconnected in pairs, both of the pairs extending perpendicularly from fingers 25 extending downwardly from the ends of an arm 26 within the beam, the fingers passing through reinforced slots 27 in the bottom of the beam 10.
  • the two arms 25 may be simultaneously moved in the same direction, so that all plungers 21 are simultaneously advanced or retracted by connecting rods 28, each pivoted at its outer end to the middle of an arm 26, and both pivoted to an eccentric pin 29 on a pinion 30 rot table within the beam 10.
  • the pinion 30 meshes with a gear wheel 31 rotatable on a stub axle 32 on a bracket 33 fixed on top of the beam, the bottom of the gear wheel passes through a slotted hole in the top of the beam 10.
  • the gear wheel 31 is of twice the radius of the pinion 30.
  • Fixed to and rotating with the gear wheel 31 is a ratchet wheel 34 with four equiangularly spaced teeth.
  • An actuating lever 35 of channelled section is fulcrumed on the stub axle 32 and within its channel there is pivoted a spring-loaded pawl 36 engaging the ratchet wheel 34.
  • the actuating lever 35 may be swung through a right angle, coming to rest at one end of its swing on a saddle 17, and at the other end of its swing on an adjustable stop 37 on the beam 10.
  • the interaction of the pawl 36 with the ratchet wheel 34 results in the gear wheel 31 being given a quarter-turn, so that the meshing pinion 30 is given a half- turn and (assuming the pinion 30 to be initially in the position shown in FIG. 1), the four plungers 21 are simultaneously advanced as shown in FIG. 2 to enter the apertures in blocks 18.
  • a cable 38 is connected at one end to the free end of the actuating lever 35.
  • the other end of the cable is made fast to the connections of the chains 16 to the crane or other lifting gear, in such a way and with such adjustment that as the slack is taken out of the chains 16, but before they apply lift to the beam, the cable 38 is so tensioned as to swing the actuating lever to its fully raised position.
  • the cable may be spring-loaded in any suitable way to avoid stress on the actuating lever 35 if the connections of cable and chains should be out of adjustment.
  • the beam 10 may be lowered onto a palleted assembly of cargo and be supported thereabove by the beam supports 14.
  • the actuating lever 35 is operated to bring all plungers 21 to their retracted positions.
  • Pallet slings as indicated in broken outline at 39 are brought between the pairs of blocks 18 and 19 and the holding plungers 20 are manually advanced, as shown at the two inner pairs of blocks in FIG. 1, to hold the slings. If desired, additional slings may be made fast to D-pieces 40 fixed under the blocks 18.
  • the crane or the like is then operated to commence lifting operations, and before the lifting chains 16 are fully tensioned, the cable 38 is tensioned to lift the actuating lever 35, so that all plungers 21 are simultaneously advanced, engaging the slings 39 previously held by the plungers 20, now displaced by the plungers 21.
  • one of the arms 24 carries an indicator pointer 41 which extends out through a slot in a side of the beam and extends upwardly. Suitable indicia with which the pointer is brought into register give clear visual indication that the sling plungers are in their operative or inoperative positions.
  • each carrying beam has associated therewith an actuating assembly as described above in relation to a single beam, modified whereby the stub axle 32 extends transversely across the spreader and the free end of each actuating lever 35 is connected to a transverse member to which the cable 38 is attached. Raising and lowering of the apparatus will simultaneously actuate all plungers 21.
  • the provision of such a device can lead to significant manpower savings, improved efficiency and greater cost- effectivness. In particular it will be seen that during lifting operations the plungers are positively maintained in their operative positions.
  • the cargo may be lifted by a crane, deposited into a remote location and released from the lifting apparatus automatically by operation of the crane, thus avoiding the necessity of employing personnel at the remote location.
  • the manually operated plungers 20 which are displaced by the plungers 21 ensure positive connection by personal supervision before the load is lifted.
  • Cargo carrying beams according to the invention will be found to be very effective in achieving the objects for which they have been devised. It will of course, be understood that the particular embodiment of the invention, herein described and illustrated by way of example only, may be subject to many modifications of constructional detail and design, which will be readily apparent to skilled persons, without departing from the scope and ambit of the invention as is defined in the appended claims.

Abstract

Volée ou appareil de soulèvement de produits, servant à soulever des marchandises palettisées telles que les balles de papier, les flancs de boeuf, les fûts au analogue. L'appareil peut s'appliquer au soulèvement des produits par hélicoptère et comprend un élément à section en caisson (10) soutenant un certain nombre de paires de blocs de retenue (18, 19) dont chacun renferme une paire de pistons (20, 21) glissants permettant de retenir des élingues pour palette (39) ou analogue. On soulève la volée à l'aide de chaînes (16). Lesdites élingues restent temporairement en place avant le soulèvement de la volée grâce au glissement manuel des pistons de retenue (20) entre les blocs de retenue. Lorsque l'on soulève la volée, un câble (38) se tend et relève un levier (35), afin d'actionner une roue d'engrenage (31), un pignon (30), des tiges de raccordement (28) et des bras (25, 26), de sorte que les pistons de verrouillage (21) déplacent les pistons de retenue (20, 21). Lorsque l'on fait baisser la volée, le câble (38) se retend et retire les pistons de verrouillage afin de libérer les élingues.
