Dolly; Tracking Dolly - Vinten HDT Heavy-Duty Operator's Manual

Dolly

The Vinten heavy-duty dolly is designed to provide a steering and castoring base for the two
heavy-duty tripods. It comprises a centre casting with carrying handle (17), a fixed leg (18) and
two folding legs (24). The dolly will support a payload of 160 kg (325 lb). The heavy-duty dolly is
available in studio, outside broadcast (OB) and tracking versions.
Studio
Each leg has a 12.5 cm (5 in.) diameter braked castoring wheel with cable guards (20). A foot sup-
port and clamp wire (22) secures each tripod leg to the dolly. Locking pins (19) in each wheel as-
sembly are engaged or disengaged to provide castor, track or steer modes.
OB
Each leg has a 15 cm (6 in.) diameter braked castoring wheel (20). A foot support and clamp wire
(22) secures each tripod leg to the dolly.

Tracking dolly

The heavy-duty tracking dolly is designed for use on standard gauge (62 cm) track. It comprises
a centre casting with carrying handle (30), a fixed leg (29) and two folding legs (25). The dolly will
support a payload of 160 kg (325 lb).
Two versions are available. One has twin 12.5 cm (5 in.) diameter wheels (27) on each leg. The
second has four 6.2 cm (2.4 in.) diameter wheels (31) on each leg, which provide a smoother pas-
sage over track joints.
The axles of the wheels are set at 90° to each other, thus locating the dolly on the track. The wheel
assembly on the fixed leg is free to move in and out on a slide (28), which allows the dolly to ne-
gotiate curves in the track.
