GF-Primo Dolly

The "one touch" selector allows for an immediate, one handed, switchover to crab, front or rear wheel steering. The maintenance free gear box also functions as a fifth, central steering position in addition to the steering positions found on each of the 4 wheel arms.

This system, among central post dollies unique to the GF-Primo, improves its mobility and maneuverability. By steering from the central position it is easier to make a straight dolly shot because the usual dolly drift, common to central post dollies, is eliminated. By pushing on centre, the dolly is easier to direct. Surface unevenness can be counteracted in either the front or rear wheel steering modes.
With a choice of 5 steering positions working on tight sets and fast dolly direction changes become a lot more manageable.

The telescopic and inclining steering rod perfects the GF-Primo's maneuverability and puts it in a league of its own. It's stability as a push or pull bar is second to none. The tilt angle can be locked off at set positions or kept in stepless, quick adjustment mode for immediate in-move position changes.

In stepless mode, even the drag can be set to individual preferences. The steering rods unique telescopic adjustment helps make the GF-Primo Dolly more user-friendly as it allows each Dolly Grip to set their own preferred individual working height.

The hand control unit fits snuggly into the steering handle to enable a comfortable and user friendly operation of the GF-Primo.
To perfect the operational comfort, the Dolly Grip can adjust the hand control unit's position to suit his own individual needs and in doing so, can be positioned at just the right angle to provide clear visibility of the informative display.

During the dolly's development stage major consideration was given to the design and functionality of the hand control unit. Coupled with cmotion's experience with their own lens control systems and GFMs knowledge and feed-back from dolly grips, the decision was made to go for a state of the art, wireless radio control.
The result is an ergonomic wireless hand control unit that rests comfortably in the user's hand, providing reliable, interference free control. Cable operation is also incorporated.

The familiar rocker switch was selected as the drive mechanism and is set at a level to give the operator ultimate control of the column. The display is clear and easy to understand, giving even first time operators confidence and guidance.
All functions can be activated from the hand control and the status of each mode is shown on the LCD display.
