I he cattle lifter in accordance with this innovation - invention comprises of two custom designed lifter frames 1-2 which are hent to specific angles. to fit a suitable. removable and adjustable two way hydraulic ram 3. This ram 3 is fitted to the lifter frames 1-2, onto two metal tabs 4-5 The tabs 4-5 have up to three aligned holes a-b-c so the ram 3 can be set to the appropriate opening and closing distances according to the cattle size. These tabs 4-5 are centered and then welded to two bars 6-7. One end of four pipe hinges 8-9-10-11 are blocked by welds, and one pipe hinge is placed on each end of the two bars 6-7. Both bars 6-7 are then welded in place.( level) onto each of the lifter frames 1-2. Welds arc placed upon the cylinder pipe hinges 8-9-10-l1. The tabs 4-5 in which the ram 3 is fixed to can now rotate 360 degrees this allows the ram 3 enough play to fully extend and fully retract. This also allows the ram 3 to be set to the desired appropriate length using the holes in the tabs 4-5. The lifter frames 1-2 are permanently welded in place onto four pipe hinges 12-13-14-15. -hese hinges are placed onto the outside of a lathed countersunk steel bar 16 Two pipe rings 17-18 are placed eachside of the bar 16 and welded in place to hold the hinges 12-13-14-15 onto the bar 16 These hinges 12-13-14-15 allow the frames 1-2 to open and close quickly accordingly. to the use if the ram 3 which is connected to the tractor by hydraulic hoses 19-20. The lifters may now be worked by means of the tractors hydraulic system, and clamped upon down cattle and put into effect as in illustrations. I is an elevation of the quick hitch and release cattle lifters, without the ram fitted. With parts separated 2 is a diagram of the ram and hoses with optional pressure control device's fitted. Showing where the ram is fitted to the lifters and other fittings dotted in red. 3 and 4 are examples of where the lifters are placed onto the animal, by means of the front end loader and hydraulic system of the tractor. |
