B60}, 1/04, 1/64 U.S. Cl. 214-505 4 Claims ABSTRACT OF THE DISCLOSURE The means for lifting a heavy goods container from the ground on to a lorry comprise a tilting chassis on the lorry, a winch with doubled cable on the chassis, a double pulley on the rear of the chassis over which the cable runs, and a pulley block on the end of the cable, the block having two side-ways extending pins at its end. The container has an insert at its front end with hooks to engage the pulley block pins. The lorry is hacked to the container, the block is hooked to the insert, and then operation of the winch draws the container on to the false chassis which is tilted to receive the container.
The present invention concerns a hooking device adapted to lift a large container from the ground onto a lorry. The practise of lifting and transporting containers on to lorries is already known.
The present invention concerns a hooking system which is to be provided on the front of the container so that the hoisting cable of the lorry winch can be removably fixed thereto.
The device according to the present invention is characterised in that it comprises, on the lorry, a tilting or false chassis with a winch at its forward end, a cable whose two ends are secured on the winch drum and which is engaged at the rear in a hooking member which comprises a throated pulley and a pulley block provided with two opposed transverse stubpins; and, on the container, a rigid lower base which carries a reinforced insert located in the centre of the lower part of the front panel of the container, said insert being provided on each side with two rollers for rolling over the false chassis of the lorry at the moment of hoisting, and a rigid centre unit formed in its upper part with two hooks between which the hooking member of the cable may be removably connected and, in its lower part, by a return guide for the cable provided with two throated circular bosses, concentric with the rollers, in each of whose throats one of the runs of the cable is passed, to return in the direction of the lorry.
It will be understood that such a device makes it possible to provide at the rear of the cable only one relatively light member, manipulation of which may be readily effected manually by one workman. Manipulation does not require the use of a special tool and the operator is able to put this member conveniently in position in the insert provided in the front of the container without having to pass under the said container at any time Reference should now be made to the accompanying drawings in which:
FIG. 1 is a perspective view showing a container resting on the ground, in front of which is a member provided on the end of the lorry cable.
FIG. 2 is a side elevation in part section showing the manner in which the lorry cable is secured to the container before hoisting the container.
FIG. 3 shows the device in the course of hoisting.
FIG. 4 is a perspective view of the insert provided on the front of the container.
FIG. 5 is a section in plan taken on the line V-V of FIG. 6 after the engagement of the cable.
FIG. 6 is a front view of the recess in the container in which the member for securing the frame is engaged.
FIG. 7 is a section taken on the line VIIVII of FIG. 6 showing the position of the front of the container relative to the rollers provided on the rear of the tiltable false chassis of the lorry.
FIG. 8 is a section taken on the line VIII-VIII of FIG. 6.
FIG. 9 is a section taken on the line IX-IX of FIG. 7 showing the passage of the cable between the return member of the container and the guide roller of the lorry.
The hooking device shown in the drawings is provided in connection with a container 19 which it is proposed to hoist on to a tiltable false chassis 10 of a lorry 1.
The container 19 is formed in known manner by walls of light sheet metal fixed to a rigid. base. The latter is formed by two main beams 21 connected by tie bars 101 uniformly distributed over the entire length The centre of the lower portion of the front panel 102 of the container 19 is provided with a rigid insert panel 103 of thick crossbraced sheet metal. The insert 103 is recessed in the panel 102 and is directly connected to the base 21.
In its centre portion the recess 103 comprises two strong vertical metal members 104 in the top of each of which a recess 105 is cut, opening obliquely upwardly and forwardly. In this manner two hooks 106 are formed.
Between the plates 104 and the lower portion of the insert a flange 107 of a guide system is welded, the system being constituted by a strong moulded member. The guide system comprises a vertical rib 108 extending forwardly out of the upper portion of the flange 1.07 the front end of which carries two cylindrical lateral bosses 109. Each of these bosses has a circular throat 110 formed in the immediate vicinity of the rib 108. To save weight, it is an advantage to make the bosses 109 hollow and to provide the centre thereof with an opening 111 which is con tinued through the rib 108.
Secured to each side of the insert and in the lower portion thereof is an axle 112 of a roller 113, the two rollers 113 and the bosses 109 being co-axially disposed. The rollers 113 and the bosses 109 are the only members of the insert 103 which extend forwardly beyond the vertical plane defined by the panel 102 of the container 19. The rollers 113 are provided to run on longitudinal rails (not shown) provided on the sides of the false chassis 10 of the lorry 1.
On the lorry 1, the device according to the invention comprises a hooking member 114 provided on the rear end of a cable 15. This cable 15 is doubled and its two runs are secured by their respective ends on a winch drum located at the front of the false chassis 10. The member 114 comprises a metal pulley block 115 between the two side plates of which a throated pulley 128 can freely rotate (FIG. 6). The axle 117 of this pulley is fixed to the side plates of the block 115. In its upper portion the block comprises two stubpins 116116, located transversely to the block. The pins are engageable in the recesses 105 of the hooks 106, whilst the block 115 is disposed'between the two plates 104 of the insert 103. In its lower portion, the block 115 receives two guide plates 129 which are disposed between its two sides, where they are secured by bolts 118. It will be seen, more particularly in FIGS. 6 and 7, that the cable 15 cannot be disconnected from the member 114 after it has been mounted thereon, that is to say, when it passes round the return pulley 128, whilst its two runs are disposed between the two opposing plates 129. To complete the assembly, the rear of the false chassis 10 of the lorry 1 is provided with a centre roller 119 which serves as a guide for the system 107-108409 at the moment when the front .of the container 19 engages the lorry (FIGS. 7, 9). The two runs of the cable 15 then rest in the throats 110 of the bosses 109, and they are prevented from being crushed by the provision of two opposing throats on the roller 119. Contact between the roller and the guide assembly 107-108-109 is established, along a centre line 121 of the roller 119 which bears on the rib 108, and along two inclined lateral lines 122 provided on the opposing taper surfaces of the roller 119 and the bosses 109. The lines 122 could also be parallel to the axis of the roller.
The operation of the device is as follows:
The container 19 is initially laid on the ground, as shown in FIG. 1. To hoist it onto the lorry, the lorry is backed in the direction of the front panel 102. By slackening the cable 15, it is possible to extend the member 114 from the lorry, which the operator brings close to the inert 103, as shown in FIG. 1. Engagement is efiected by placing the two stubpins 116 in the recesses 105 of the books 106 (FIG. 6), then by placing the two runs of the cable 15 into the respective throats 110 of the bosses 109. The runs of the cable 15 also enter the throats 120 of the roller 119 provided on the rear of the lorry 1. The unit is then ready for hoisting (FIG. 2).
The operator starts the winch (not shown) provided on the front of the false chassis 10 and draws the cable in the direction of the arrow 123- (FIG. 3). During all these operations, the bosses 109 hold the runs of the cable 15.
When the front of the container 19* reaches the rear of the lorry, contact is effected between the rollers 119 and the guides 108-109. The rollers 113 begin to run over the longitudinal rails provided on the sides of the chassis 10 until the container 19 is completely hoisted on to the lorry. Thereafter the container may be clamped or locked in position if required. Unloading is elfected in a reverse manner to that described above.
It should be understood that the above description is given only by Way of example and does not limit the scope of the invention. In particular the scope of the in- 4 vention would also include modifications of the form or arrangement of the metal ribs 124, 125, 126 or 127 (FIG. 4) provided to reinforce the insert 103.
