Rest Adjustment; Ratchet Crank Operation And The Ratchet Crank-Lever - Brano 15-00 Operation Manual

6.2 REST ADJUSTMENT

(only design - VK).
Position of the adjustable rest can be changed in the
range given by a number of mounting positions on the
jack bar (see fig.1)
After removal of the breaking piece (2) and shifting of
the rest in the direction indicated by an arrow,
fastening pin (1). 2 get loose in the jack bar and rest
can be put out. Carry out rest fitting-on to other position
by opposite procedure.

6.3 RATCHET CRANK OPERATION AND THE RATCHET CRANK-LEVER

(only design – RK and – RKP).
6.3.1 Raising or lowering
Before raising
changeover lever and set on the
mark of raising – up-arrow (see fig.5).
Carry out the raising by oscillating
(eventually rotation) motion of the
ratchet crank.
At the beginning of the raising before
the loading of the rack jack will take
place, hold the knurled nut so that it
would not be carried away by the
crank at its backwards motion.
Before lowering the load, shift the changeover lever to the position on the lowering
mark – down arrow (see fig.5). Lower down the load by oscillating (eventually
rotation) motion of the ratchet crank.
Make sure at each change of the position of the changeover lever, whether the lever
gets fitly to the socket in the ratchet crank.
First motion of the ratchet crank after reversing (after shifting of the changeover
lever) is slightly blocked. This state arises by an influence of stronger follow-through
of the brake namely at manipulation with heavier loads. In this case release the brake
by more point-blank motion, thereby you will coincidently release the ratchet crank.
6.3.2 Ratchet crank-lever
The manipulation with the ratchet crank-lever during the lifting and lowering of loads
is performed in the same way as is stated in article 6.3.1 and 6.3.2.
The ratchet crank is changed to an extended lever by folding the crank-lever handle
0
by 90 (into the lever position - see fig.3). We use this position for decreasing the
control force during the manipulation with loads that are close to the nominal lifting
capacity of the lifter.
The ratchet crank-lever is equipped with a safety shear pin against overloading (see
fig.3)
If the shear pin is sheared during the manipulation with a load, it is still possible to
lower the load even if the shear pin is sheared (after moving the reverse lever to the
lowering position).
