Operations Manual: Drum winch rope routing

For smooth operations and having the remote control levers

aligned with the directions of the drum winches: make sure the rope ‘leaves’

the drum winches as mentioned in these pictures !

As well, make on all rope ends a ‘loop’

Remark:Make sure the rope loopfits on the ‘wedge belt wheel’of the hook.

Rope leaves winch at rear side Rope leaves winch at rear side

Boom rope set-up

1x Rope ‘medium thickness’

250cm,

Part x77cc250,

See LEGO®

mobile crane sets 8421 & 42009

1) Starting point: Rope with loop

2) Wind rope around wheel, then back to top of A-frame

3) Wind rope on wheel and twist it around the black pins and orange wheels to secure it.

~ 90 degrees !

2) Mount rope loop onto the black pin (temporary remove the green 3L beam thin)

1) Wind the rope over the wheel rims ‘back-and-forth’

3 times

EXAMPLE


Operations Manual: Dragline bucket (1)

Guide rope carefully through

the hole between the ‘black beam’

and the ‘black bar’

EXAMPLE


Operations Manual: Dragline bucket (2)

Rope loop of upper winch

Rope loop of lower winch

Guide rope through ‘pin hole’

and lock the rope within the groove of the ‘towball pin’

Rope distance between locked rope (1) and rope

end (2) is: ~ 47 cm

EXAMPLE


Operations Manual: Double rope lifting

Guide rope of the lower drum winch through the black axles (red circle) to the 2nd

pully at the ‘boom head’

EXAMPLE


Operations Manual: When the boom M-motor ‘slips’

During operations it should NOT occur that the boom winch Power Functions M-

motor for raise/lower the boom slips due to the applied weight of the boom + loaded bucket.

However, if this might be the case (probably due to much load into the bucket, or adding more boom extension frames) it is possible to prevent this from happening.

Just add a black 12 tooth double bevel gear (part 32270) on the blue axle/pin.

EXAMPLE


Operations Manual: Transport readiness

Lock the ‘boom foot’

orange 3L beam with an axle (red arrow) onto the A-frame. As such the boom-foot can be raised / lowered together with the A-frame.
