Introduction; Single-Stage Tripod (Hdt-1); Two-Stage Tripod (Hdt-2); Elevation Unit - Vinten HDT Heavy-Duty Operator's Manual

®
The Vinten HDT Heavy-Duty Tripod Range includes single- and two-stage tripods with mid-level
spreaders; OB, studio and tracking dollies and an elevation unit.

Single-stage tripod (HDT-1)

The single-stage tripod has a minimum height of 59 cm (23.2 in.). When used with a floor spread-
er, maximum height is 123 cm (48.4 in.). Mounted on a dolly, the height range is 86.2 cm to 142.2
cm (34.0 in. to 56.0 in.).
Each leg has a three-position swivel foot assembly (5), which provides a flat foot for studio use or
a spike for use on soft ground. When set to the third position, the foot and spike are turned inwards
for transit or for installation on a dolly or floor spreader. The innovative leg clamps
a self-limiting mechanism which provides a guaranteed clamping force and prevents overtighten-
ing. Graduations on the legs facilitate deployment. Clips
closed position.
A mid-level spreader (9), attached to each leg, is free to slide on the spreader support tube (8).
The spreader is retained on the tube by a spring-loaded release button
by a clamp (10).
A fold-away carrying handle
ditional security in adverse conditions. One is positioned under the tripod head, the other at the
base of the spreader support tube.
The pan and tilt head is attached to the tripod using four captive mounting bolts
ell-type centre screw. The Vinten Heavy-Duty Quickfix
bubble (2) is provided.
Maximum payload capacity is 140 kg (308 lb).

Two-stage tripod (HDT-2)

The two-stage tripod is basically similar to the single-stage tripod, but with two-stage legs. The
minimum height is 51.1 cm (20.1 in.). Maximum height with a floor spreader is 146 cm (57.5 in.).
Mounted on a dolly, the height range is 78.3 cm to 166.3 cm (30.8 in. to 65.5 in.).
Maximum payload capacity of the HDT-2 is 120 kg (275 lb).

Elevation unit

The elevation unit attaches directly to the single-stage tripod and has a height range of 45.8 cm
(18.0 in.). It will support a maximum payload of 113 kg (250 lb). Elevation is achieved by a geared
handle (15) and an on-shot clamp is provided (16).
The elevation unit should not be fitted to the two-stage tripod, as stability is reduced when the el-
evation unit is fully extended.
The pan and tilt head is attached to the elevation unit with a four-bolt fixing as standard (14), with
provision for Mitchell, Quickfix and 100/150 mm bowl adaptors as options.
