Introduction
1 The Vinten Pan and Tilt Head Mk 5, Fig. 1, is a light-weight unit designed with the modern compact
broadcast camera in mind. The Mk 5 incorporates the well proven Vinten cam and roller bearing system,
which provides a smooth positive action, coupled with perfect balance throughout the operable tilt range of
120°. The operating capacity of the Mk 5 is designed for loads up to 81.65 kg (180 lb), and this is achieved
with a unit weight of 11 kg (24 lb). The design embodies the latest Vinten developments in pan and tilt friction
mechanisms.
Description
2 The head consists basically of the three following main parts:
2.1 Wedge Adaptor Assembly
2.2 Head Assembly
2.3 Body Assembly
Wedge adaptor assembly
3 A Vinten wedge adaptor assembly is fitted to the head assembly. The wedge adaptor assembly
functions as a locator and locking unit for the camera when this is fitted with a standard camera wedge e.g.
Vinten part number 3053-3. It consists of a wedge adaptor, which receives the camera wedge, and a locking
bar which retains the wedge in position. The wedge adaptor assembly is attached to the head assembly by
three socket headed screws passing through slots in the head assembly and screwing into the wedge adaptor
plate. The adaptor assembly is free to move in a fore and aft direction on the top surface of the head
assembly, under the influence of the leadscrew when the socket headed screws are loose. These screws are
fitted and tightened or slackened and removed using an Allen key wrench that is housed in a recess in the rear
of the platform of the head assembly.

Head assembly
4 The head assembly is a machined alloy casting in plate form, with slots and recesses milled out for the
installation of the side guide bars, the fine C of G adjustment block and the wedge adaptor securing screws.
The following items are secured to the head platform.
Side guide bars
5 These are of square section with a channel milled out on one bearing edge and a limit slot milled out on
the inside face. The guide bars are secured by spirol pins to a pair of steel pivot pins which are in turn housed
in a pivot pin bearings; these being secured to the underside of the platform by socket headed screws passing
through the platform from the top face.
Cams
6 These are installed as matched pairs and are secured to the underside of the platform by socket
headed screws, each cam requiring 6 screws passing through the platform from the top face.

Fine adjustment screw
7 This is a leadscrew mounted in a pair of bearer blocks that are fixed to the underside of the platform,
each by four socket headed screws passing through the platform from the top face. The leadscrew is provided
with a knurled thumb nut that projects clear of the rear of the platform. A block with a steel spigot runs along
the thread of the screw; the spigot projects above the top face of the platform and engages with a recess in
the wedge adaptor plate
Locking plates
8 Two locking stays are fitted on the underside of the platform. Each stay is secured to a mounting block
by a shouldered bolt and locked by a hexagon nut. Each block is secured by two countersunk screws passing
through the platform from the top face. Each locking stay is retained in the folded position by a spring clip. The
locking stays match up with locking s
Tilt friction
9 This consists of a quadrant plate secured to the left side of platform (view from rear) by four
countersunk screws. The friction pads are fitted, one to a fixed block attached to the side guide bar, and the
other attached to the adjustable block. Friction is applied by turning the knurled thumb nut in a clockwise
direction. The friction pads are of leather and are attached to the block by adhesive and are pinned. The tilt
lock is similar to the tilt friction except that it is fitted to the right hand side and is operated by a simple ON/OFF
lever. The lock pads are of standard brake lining material.
Body assembly
10 The body assembly is a robust alloy casting providing the location for the side bar mechanism in the
integral arms, and the panning mechanism in the base. Each integral side member provides the recess in
which the bearing system is installed. These bearings support and position the side guide bars. Each bearing
system consists of two ballraces with fixed mountings and two ballraces on eccentric screws. One end of each
ballrace spigot is mounted in the side member of the casting whilst the other end is carried in the closing
plates. On the inner section of each integral side member location is provided for a cam roller, which consists
of a ballrace positioned on a shaft by spacers, the shaft being secured in place by a socket set screw.
Immediately below the cam roller a recess is provided for the side bar stop pin, this is held in place by a socket
set screw. The stop pin projects through the side arm and into a slot in the side guide bar, thus the limit of
travel is defined by the length of the slot. On the upper surface of the body casting are two small projections,
each of which carries a threaded stud with a knurled thumb nut the resultant action of which forms a clamping
device for the head locking plates. Finally a spirit level is mounted on the top face of the body, near to the pan
and tilt controls.
Base
11 The base is a machined cast alloy unit which provides the mounting face and pivot for the complete
assembly. The base takes the form of a thick circular disc with a deep flange on the upper surface and four
threaded holes on the underside, together with mounting bolt holes in the centre. Each mounting hole has a
3/8 in. BSW wire thread insert.
Panning
12 The base top face is fitted with a thin crush washer, a needle thrust cage and a housing washer. This
forms the bearing assembly on which the body turns. The base, together with the friction and lock assembly,
are fitted to the body by a special bolt passing from the bottom of the base through to the top side of the body.

The upper end of the bolt is centralised by a ballrace, and this is secured in place by a special nut. Both nut
and bolt are positively locked by countersunk screws.
Pan lock
13 This consists of a pair of brake shoes complete with linings, pivoted on the pan lock adjuster assembly,
and expanded by the brake cam.
14 The shoes are tensioned away from the raised section of the flange of the base plate by two springs.
The assembly is fitted to the underside of the body and retained in place by a thin plate. The brake shoes
operate against the inside face of the flange. The adjuster protrudes through the top face of the body and
terminates as an adjuster screw with a 2BA locknut. The brake cam is located within a bush and is retained by
an external circlip. The pan lock lever assembly is attached to the head of the brake cam spindle, and travel is
limited by raised portions of the body.
Friction
15 This consists of two brake segments, pivoted at one end on pins that are fixed to the body. The
segments bear against the outer periphery of the flange of the base under the influence of a pair of springs
that are tensioned by the action of the friction screw thumb nut screws on the body assembly e flange of the
base under the influence of a pair of springs that are tensioned by the action of the friction screw thumb nut

Balancing head/camera
6 To balance head/camera release and stow locking stays at the same time restraining any excessive
movement of the head by holding the pan bar. Centralise the camera to the level position and under restraint
allow camera to tilt. When tendency to fall away in one direction is noted, adjust C of G as follows:
6.1 Ensure friction and lock of tilt assembly are released.
6.2 Using Allen key slacken off three socket headed screws just sufficient to permit movement of
wedge adaptor relative to head (Fig 2.2). If tendency of camera is to tilt forward turn thumb nut at rear of
head clockwise to bring wedge adaptor rearward. Counter clockwise movement of thumb nut is
required to move head forwards.
6.3 When balance is achieved tighten socket set screws and stow Allen key in its position on the
head platform.
7 If, when adjustments outlined in 3a to e have been carried out, the camera falls forward and backward
heavily, the C of G of the camera is too high for the cams fitted. If the camera centres heavily the centre of
gravity is too low for the cams fitted.
Adjustment of controls
8 Controls are adjusted as follows:
8.1 Tilt friction is applied by turning thumb nut clockwise.
8.2 Tilt lock is applied by moving lever rearwards.
8.3 Pan friction is applied by turning thumb nut clockwise.
8.4 Pan lock is applied by moving lever from right to left.
NOTE: It is essential to ensure that socket set screws are completely tight after adjustments are
carried out.
NOTE: It is necessary to ensure that the locking plates are in the locked position whenever:
1. An out of balance load is put on or taken off the head.
2. The camera is out of use for any prolonged period.
3. The mounting and camera are moved over long distances when in studios or vehicles.

Introduction
1 The Mk 5 Pan and Tilt Head is 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. If the head becomes faulty reference should be made to
Section 5 of this manual, or the unit may be returned to Vitec Videocom limited or your local dealer for repair.
Cleaning
2 During normal use the only cleaning required should be a regular wipe over with a lint-free cloth. Dirt
accumulated during storage or periods of disuse may be removed with a semi-stiff brush. Particular attention
should be paid to the wedge location faces of the wedge adaptor.
3 Use out-of-doors under adverse conditions may require special attention and the head should be
covered when not in use. Salt spray should be washed off using fresh water at the earliest opportunity. Sand
and dirt act as an abrasive and should be removed using a semi-stiff brush or a vacuum cleaner.
Adjustments
4 The following adjustments may be necessary after considerable usage:
4.1 Elimination of fore and aft play in the side guide bars.
4.2 Compensation for wear in the friction pads of the tilt friction and lock and the pan friction and lock.
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.
