TwinDolly
Tools: 13 mm open wrench and 5 mm Allen key
Operation Instructions
-
Precautions and Notes
Using common sense nothing can go wrong.
-
Whenever possible use Tip Protection. [1]
-
Always use clamps or junior studs as end
stoppers if our End-Stops are not available.
-
Two of the side wheels of a TwinDolly/TrussDolly
are mounted on offset axles. This makes it
possible to adjust the track width 6mm per axle,
thus 12mm per TwinTube or truss. Remember to
use the same setting for each axle, otherwise the
dolly will run obliquely along the rails.
General Remarks
All bolts that are not intended to be removed are
factory treated with Loctite 2701.
Excluded are: Brake, Tip Protection, Wheel shafts.
The top wheels have a diameter of 62mm and a
hardness of 78A.
The TWD side wheels have a hardness of 94A.
These values are the result of extensive testing.
Deviating from these values may negatively effect
the operation of the TwinDolly.

Tools: 13 mm open wrench and 5 mm Allen key
Operation Instructions
Offset Axle Adjustment Procedure
Fully release the brake.
Locate the Offset wheels opposite of the
Brake.
Loosen the Allen bolts of the wheel sets half
a turn. [2]
Use a 13mm wrench between the wheel
and the dolly to turn the axle to the desired
position. [3]
When the desired position is achieved re-
tighten the axle with an Allen key.
Check that the dolly can run freely in a
straight line without play but also without
too much pressure.
If the wheels are over tightened flat spots
can occur resulting in a bumpy dolly
movement.
If the wheels are too loose there will be play
in the dolly which will be felt at camera
pans.

Operation Instructions
-
Set up for use on a standard Rigging Truss.
When using wider truss or rigging, the offset
axles can be placed in the outer holes.[4].
Further adjustment is similar to the previous
described process.
BNC Arm
The hinged arm is intended to hold BNC or power
cables at a comfortable distance from the
dolly.[5]
4 Way Leveler
Installation of the SolidGripSystems 4-Way-
leveler goes best when following the next
suggestion:
first turn three of the leveling bolts of the leveler-
head maximum out and the remaining bolt fully
inwards before starting to assemble.
