Description

       

  INRICHTING TOT HET IN EVENWICHT

BRENGEN VAN GIEK EN LASTOPNAMEMIDDEL

BIJ HYDRAULISCHE KRANEN OF BAGGERS

  
 <EMI ID=1.1> 

  
in evenwicht brengt in iedere stand door verplaatsing

  
van het zwaartepunt.

  
2) dit zelfde tegengewicht is verbonden door stangen met

  
de voorarm of knikarm en lastopnamemiddel. Door deze

  
stangen wordt het zwaartepunt een tweede maal verplaatst

  
teneinde ook deze knikarm met lastopnamemiddel in evenwicht

  
te brengen.

  
3) de laatste en juiste correctie wordt verkregen door de druk

  
in de knikarmcylinder over te brengen op een hulpcylinder

  
die een derde automatische correctie geeft aan het tegengewicht.

  
4) daar het geheel altijd in iedere stand in evenwicht is,

  
wordt alleen energie verbruikt om de netto-last te

  
verplaatsen en deze energie-besparing kan bij dit type

  
 <EMI ID=2.1> 

  
van 50 PK hetzelfde werk verrichten. 

  
5) door deze inrichting wordt ook de hoofdarm gebruikt

  
 <EMI ID=3.1>  

  

 <EMI ID=4.1> 




  DEVICE FOR BALANCING

BRINGING THE BOOM AND LOADS

FOR HYDRAULIC CRANES OR BAGGERS

  
 <EMI ID = 1.1>

  
balances in any position by displacement

  
from the center of gravity.

  
2) this same counterweight is connected by rods with

  
the forearm or articulated arm and load handler. By this

  
rods, the center of gravity is moved a second time

  
so that this articulated arm is also in balance with the load handler

  
to bring.

  
3) the last and correct correction is obtained by the pressure

  
in the folding arm cylinder to transfer to an auxiliary cylinder

  
which gives a third automatic correction to the counterweight.

  
4) since the whole is always balanced in every position,

  
energy is only used to calculate the net charge

  
and this energy saving is possible with this type

  
 <EMI ID = 2.1>

  
of 50 HP do the same work.

  
5) the main arm is also used by this device

  
 <EMI ID = 3.1>

  

 <EMI ID = 4.1>
