Introduction
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 spreader, 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 (11) incorporate
a self-limiting mechanism which provides a guaranteed clamping force and prevents overtightening. Graduations on the legs facilitate deployment. Clips (4) on each leg retain the tripod in the
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 (7) and locked in position
by a clamp (10).
A fold-away carrying handle (3) is fitted at the top of one leg. Two tie-down hooks (6) provide additional 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 (12) or by a Mitchell-type centre screw. The Vinten Heavy-Duty Quickfix
bubble (2) is provided.
Maximum payload capacity is 140 kg (308 lb).
®
Adaptor may also be used. A levelling
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 elevation 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.

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 support and clamp wire (22) secures each tripod leg to the dolly. Locking pins (19) in each wheel assembly 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 negotiate curves in the track.

Studio and OB dollies
Assembling the dolly
Turn the dolly upside-down, depress the leg locking plungers and pull each folding leg out until
the plungers lock the legs in the open position.
Set the dolly on the ground on its wheels and apply the wheel brakes.
Brakes
Each of the dolly wheels is fitted with a foot operated brake (21). The brakes are applied by press-
ing down on the lever situated above the wheel and released by pressing down on the centre
`pop-up' lever (21.1) which is raised when the brake is on.
Cable guards - studio version only
The cable guards (20) are height adjustable and should be set as required. Adjustment is carried
out by slackening the knobs (20.1), setting the cable guard at the required height and re-tightening
the knobs.
Dolly movement - studio version only
The wheels on the dolly can be locked in the straight-ahead position or set to castor freely. The
castor/lock changeover is effected by spring-loaded track lock pins (19) on each wheel assembly.
The pins on the folding legs have black knobs and the pin on the fixed leg a red knob. To engage
or disengage a pin, pull it up against the spring and turn through 90°. The pin will only engage with
the wheel when the wheel is properly aligned. This arrangement provides castor, track and steer
motion.
Castor motion
For castor motion, disengage all three track locks. The dolly can now be moved freely in any direction.
Tracking motion
For tracking motion, engage all three track locks. The dolly can now track backwards and forwards
in a straight line.
Steer motion
For steer motion:
Position the dolly so that the fixed leg (with the red knob) is in the direction of travel. Disengage the red track lock.
Engage the black track locks.
With the fixed leg of the dolly facing forwards the dolly can now be moved with a `steering-type' motion.

Servicing
General
Vinten products are robustly made to high engineering standards and little attention is required to
maintain serviceability save regular cleaning. Attention to the following points will ensure a long
and useful service life with minimum need for repair.
Cleaning
During indoor use, the only cleaning required should be a regular wipe over with a lint-free cloth.
Dirt accumulated during storage may be removed using a semi-stiff brush. Particular attention
should be paid to the leg clamps and the tripod mounting face.
Use out-of-doors under adverse conditions will require special attention. Salt spray should be
washed off with fresh water at the earliest opportunity. Sand and dirt acts as an abrasive and
should be removed using a semi-stiff brush or vacuum cleaner.
NOTE: Use only detergent-based cleaners. DO NOT use solvent- or oil-based cleaners,
abrasives or wire brushes to remove accumulations of dirt, as these damage
the protective surfaces.
Clamp sleeves
The leg clamps are fitted with removable clamp sleeves. In the event that sand, d irt or other contaminants have entered the clamp the sleeves may be removed for cleaning, as follows.
NOTE: Figure shows a top clamp. Other leg clamps are of similar construction.
Remove any payload from the tripod.
Release the leg clamp.
Grip the knob (11) and remove the retaining screw (11.3).
Unscrew the knob (11) until the clamp plate (11.2) and spherical clamp nut (11.4) can be
removed from the clamp housing (11.5).
Rotate the clamp sleeves (11.6) inwards so that the lugs on the sleeves line up with the cut-
outs in the clamp housing (11.5).
Slide the clamp sleeves up the tripod legs until they are clear of the clamp housing.
Using a semi-stiff brush or vacuum cleaner, remove any dirt from the faces of the clamp
sleeves and the inside of the clamp housing.
WARNING! Do not attempt to remove the clamp sleeves from the tripod
legs. If a clamp sleeve is damaged it should be replaced by qualified personnel in accordance with the Maintenance Manual
(Publication Part No. 3901-9).
23
Page 24
Refit the clamp sleeves by aligning the lugs on the sleeves (11.6) with the cut-outs in the
clamp housing (11.5) and sliding them down the legs.
Rotate the clamp sleeves outwards so that the lugs on the sleeves locate in the cut-outs in
the clamp housing.
Position the clamp plate (11.2) in the clamp housing (11.5), ensuring the lugs on the clamp
sleeves (11.6) are correctly located.
Position the spherical clamp nut (11.4) in the clamp plate (11.2), ensuring that the curved
face of the nut is towards the clamp plate.
Screw the knob (11) into the spherical clamp nut (11.4) until the clamp is finger-tight.

stop and the fully ‘on' position exceeds 120°, adjust the clamp as follows:
Remove the hole plug (16.5). Remove the screw (16.4) and washer (16.3) securing knob
(16) to lock spindle (16.2). Remove the knob.
Turn spindle clockwise to fully tighten clamp, then turn counter-clockwise 120° (two flats).
Position knob on spindle so that it is against the stop screw (16.1). Ensure that rotation to
fully ‘on' is less than 120° and that the clamp is fully ‘off' when against the stop screw. Remove knob and rotate spindle until this is achieved.
Secure knob with screw (16.4) and washer (16.3), using Loctite 222E. Refit hole plug
(16.5).

Studio dolly tracking
Adjustments to the tracking of studio dollies may become necessary after considerable use.
Check the tracking as follows:
With the track locks engaged and a payload fitted, the dolly should track in a straight line
over a distance of 3.6 m (12 feet) with deviation not exceeding 5 cm (2 in.). If this cannot
be achieved, the wheels should be re-aligned. When re-aligning the wheels, start by adjusting the wheel with the red locking knob on the fixed leg. This will often correct any alignment
problems.
To re-align the dolly wheels:
Remove the tripod from the dolly.
Slacken screw (19.3).
Remove the bolt (19.1) and washer (19.2) securing the castor to the fixed leg. Apply Loctite
270 to the bolt and refit bolt and washer and tighten lightly.
Engage the track lock (19) on each castor.
Align the wheel on the fixed leg so that it runs parallel to the leg.
Using a suitable straight line on the studio floor, check that over a distance of 3.6 m (12 feet)
the deviation does not exceed 5 cm (2 in.). Re-adjust the wheel until this is achieved. If it
cannot be achieved, the wheels on the other two legs should be re-aligned.
Once the wheels have been correctly aligned, tighten bolts (19.1) and screws (19.3).
