1. De kraan bestaat uit een vertikale mast (A) en tuee gieken(B,C) opgehangen aan trekkabels of stangen (D,E) Het geheel draait op een centrale kroon of spil (F)
Er zijn twee of meerdere takels (G,H,)voorzien om de last te hij- sen of te dalen,daarbij is een of meer takels (I) voorzien om de gieken gelijktijdig te hijsen of te dalen.Dit alles tot nu toe gekend. De nieuigheid volgt: Om de hijskracht over grotere afstand

De last (J)word naar de geuenste plaats gebracht door de gieken

Er is dus volkomen evenwicht.De inhoud van container (L) uord overgeheveld of overgepompt in container (M)tot dat het geuicht van de last (K) bereikt is.De container (L) moet leeg zijn.

1. The crane consists of a vertical mast (A) and tuee booms (B, C) suspended from pull cables or rods (D, E). The whole unit runs on a central crown or spindle (F).
Two or more hoists (G, H,) are provided to lift or lower the load, and one or more hoists (I) are provided to simultaneously hoist or lower the booms. All this known so far . The novelty follows: For the lifting power over greater distances
<EMI ID = 2.1>
counter-weight that always approaches the weight of the load and thus does not lose a moment in crown or pivot (F) and in the vertical mast
(A), so that the whole without end is always in balance.
<EMI ID = 3.1>
is on site with an empty container on top. On the other side hangs a container (L) with e.g. b. a liquid filled whose weight corresponds to the load (J), since the self weight of (L) is equal to (M) and the filling of (L) has the same weight as the load (J), so everything is in balance.
The load (J) is brought to the desired position by the booms
(B, C) and by turning the yoke, then put the load (3) and container (L) down at the same time, the first at the predetermined position and the tether on the newly applied load (K ). So there is perfect equilibrium. The contents of container (L) are transferred or pumped into container (M) until the level of the load (K) is reached. The container (L) must be empty. The load (K) is hooked on and the load (J) is released. Both sides are lifted simultaneously (sides = loads) So that
<EMI ID = 4.1>
provided with a switch that prevents movement under uneven load. The containers can also be located in the boom (B, C) or replaced by solids which make the use of a container unnecessary.
