Dynabloc hydraulic & mechanical to 3 point lift.
To overcome the rear lift issues of its first vigneron 509 and 511 tracteurs Ets Patissier developed a manual operated cable rear lift system in the early 1950s. This was a lever system pulling through gears and ratchet a cable to raise the towing hook for the implements required to be towed by the tracteurs. Named the type B it was also used for the 509/511 and later on the 510, 512, 518 tracteurs till 1955.
Mr A Patissier under the brand Energic developed and patented (Brevté S.G.D.G.) a new system of rear tracteur lift known as the Dynabloc. This was available at the time of the type B manual cable rear lift and subsequently took over the role as the rear lift mechanism for all Energic brand tracteurs having a greater lift capability and hydraulically operated.
Under the Dynabloc name 2 types of rearlifts/d’Attelages where available; Revelage automatique and the other revelage méchanique. Mr A Patissier patented this relevage system/mechanism in France and abroad – (Patent/Brevté S.G.D.G.)
The speed of and descent can be regulated from the steering wheel with a pre-selection of the height required for the most effective implement operation.
The system in prototype form was put through rigorous performance trials involving over 200 000 lift of a standard weight of 250 kgs. This usage equates to 15 to 20 years of usage on an average middle size farm of 1950/’60s in France. This weight constituted, at the time, the max. weight of a 2/3 soc plough the heaviest implement that this size of tracteur would normally lift with a rear lift system. The trials proved a great success, the sequence of lifts was concluded without any loss of power or performance. The average annual lifts per hectare are between 100 and 300 when ploughing.
The Dynabloc system, which came into service in 1954, is designed to give you the best and accurate control of depth, force, and height of the implement for all activities from ploughing, to cutting hay, hoeing, drilling etc. The Dynabloc system enables both adjustments in the vertical and horizontal planes of the implements attached to this rear lift system.
****The 3 Rear lifts options that Energic offered on its early tracteurs – (before the universal 3 point hitch)*****
Type A – Manual lift. (here seen on an early Energic 511 tracteur). This is the earliest system operated with a lever system pulling through gears and ratchet a cable to raise the towing hook for the ploughs etc.
You could either pull the implements/outils directly behind the tracteur or set them at an angle to suit the type of agriculture, viticulture you were operating in.
Type B – Dynabloc S (Attelage type S). Low maintenance Mechanic/méchanique, lifting capacity of 250 kgs, The PTO/prise de force comes out of the back of the Dynabloc system when lifted out of the way. You can either tow from the hitch – chap/crochet on the Dynabloc or use the bar to lift implements/outils. This system was fitted to the early 511/510/512 tracteurs as shown on the vigneron 511 photo above.
Type C – Hydraulic lift/revelage hydraulique. Using a bar lift system the type 519 – operating through the pressure of oil through/in the Dynabloc, that can be infinitely variable for height, tolerance and pressure.
Energic l’attelage Dynabloc series 500 tracteur.
Energic patented attachment procedure for implements on the Dynabloc lift/revelage, from 1, the positioning the tracteur lifting bar in – to the final hitch on position 5.
Finally, the Energic tracteurs used the universal conventional set up of the 3 point linkage. Often made by specialist manufacturers like MGF. These were a stand-alone block with lifting arms that was run from a hydraulic pump directly from the engine/ fan belt set up. These were later replaced by a system that was integral in the rear section of the tracteur (tracteur Steyr based 430, 540, 550, 560 and 580 badged Energic from 1965) with their own internal high-pressure hydraulic pumps. They could lift lifting 1 to 3+ tons – not just the 250/400kgs Dynabloc of the early Energic brand tracteurs.
Adapted the Dynabloc with a welded top point link (as in the left-hand photo above) gave a 3 point system. Or the newer independent bolt-on lifting bloc with a 3 point hydraulic lift. (in the right-hand photo).
The universal/conventional set up of the 3 point linkage. Made by specialist manufacturers such as MGF and Ramus – see below. As advertised for the Series 2 Energic 519 tracteur diesel of the late ’60s. These were a stand-alone block with lifting arms that was run from a hydraulic pump directly from the engine/ fan belt set up.
These were later replaced by a system that was integral in the rear section of the tracteur (tracteur Steyr based 430, 540, 550, 560 and 580 badged Energic from 1965) with their own dedicated internal high-pressure hydraulic pumps. They could lift lifting 1 to 3+ tons – not just the 250/400kgs Dynabloc of the early Energic brand tracteurs.
