manufactures a large range of control cables, such as
accelerator, speedometer, brake, clutch, bonnet and boot.
Control cables are flexible cables used to transmit mechanical
force by the movement of an inner cable (most commonly of steel
or stainless steel) relative to a hollow outer cable outer
casing. The outer casing is generally made up of a helical steel
wire, encased in a plastic outer sheath commonly made of PVC
which is extruded onto the steel wire.

What Is A
linear movement of the inner cable is most often used to
transmit a pulling force. They can exert a push/pull force
where the application requires, such as gear shift cables,
and throttle cables for heavy duty vehicles and machinery,
marine applications or light aircraft . Usually provision is
made for adjusting the cable tension using an alloy
component such as a screw or barrel adjuster, which
lengthens or shortens the cable outer casing relative to a
fixed anchor point.
The “end fittings” of the inner cable vary and may either be
a small shaped piece of metal, such as a nipples or hooks,
or eyes or adjusters which fit into the applicable vehicle
component.. The force that these ends will be able to
withstand is tested by subjecting each to a “pull test”
which exerts a sudden and specific pull pressure onto each
“end fitting” at the same time. Anropa tests each cable
before it is deemed ready for sale.
Metal Ferrules are crimped onto each end of the outer to
prevent cable ends from fraying.
Bowden cables can cease to function smoothly, particularly
if water or contaminants get into the outer casing. Anropa
insert liners in between the outer and inner casings (where
application requires)and fits dust preventing grommets onto
the inner to prevent dust and sand entering the outer
casing. Where the outer casing is exposed to heat from the
engine or manifold extra Heat Protective Material is affixed
to the cable at the “hot spot”.
Cables For Vehicles
For automotive applications, the control cables are used to
complete controlling actions such as:
Accelerator (or throttle) cables - this control cable allows
the driver to regulate the amount of power he produces whed he
depresses the accelerator pedal. In a carbureted engine, the
accelerator cable opens a valve in the carburetor when the
accelerator pedal is depressed. In the case of a fuel injected
engine, the throttle valve is placed on the entrance of the
intake manifold, or housed in the throttle body..
gasoline internal combustion engine, the throttle is a valve
that directly regulates the amount of air entering the engine,
indirectly controlling the charge (fuel + air) burned on each
cycle due to the fuel-injector or carburetor maintaining a
relatively constant fuel/air ratio.
the throttle valve is controlled with a throttle pedal or lever
via an accelerator cable. All Anropa Accelerator cables are
subjected to a pull test of 150kg during production process.
This is to ensure that the mechanical parts do not pull the
cable apart during operation in the vehicle.
Clutch cables operate the clutch from the clutch pedal.
In a modern car with a manual transmission the clutch is
operated by the left-most pedal using a cable connection from
the pedal to the clutch mechanism. Even though the clutch may
physically be located very close to the pedal, such remote means
of actuation are necessary to eliminate the effect of vibrations
and slight engine movement, engine mountings being flexible by
design. With a rigid mechanical linkage, smooth engagement would
be near-impossible because engine movement inevitably occurs as
the drive is "taken up." Smooth operation with a clutch cable is
ensured by inserting a liner between inner and outer so that
there is even less friction when the cable is operated, or by
using a self adjusting mechanism on the cable.
The default state of the clutch is engaged - that is the
connection between engine and gearbox is always "on" unless the
driver presses the pedal and disengages it. If the engine is
running with clutch engaged and the transmission in neutral, the
engine spins the input shaft of the transmission, but no power
is transmitted to the wheels.
With an automatic transmission, a gear shift or shifter cable is
required to actuate the gear shifting lever and the
transmission. The transmission shifting is accomplished by a
gear shift cable which puts the vehicle in Park, Reverse,
Neutral and Drive positions through a lever mounted on the
steering column or a gear shifter near the center console.
shift cables tend to be heavy duty and longer than other control
cables on the vehicles.
Brake cables In cars, the parking brake, also called hand
brake, emergency brake, or e-brake, is a latching brake usually
used to keep the vehicle stationary. It is sometimes also used
to prevent a vehicle from rolling when the operator needs both
feet to operate the clutch and throttle pedals.
hand brakes usually consist of a cable directly connected to the
brake mechanism on one end and to a lever or foot pedal at the
driver's position. The mechanism is often a hand-operated lever
(hence the hand brake name), on the floor on either side of the
driver, or a pull handle located below and near the steering
wheel column, or a (foot-operated) pedal located far apart from
the other pedals.
The parking brake operates mostly on the rear wheels, which have
reduced traction while braking.
handbrake is applied, the brake cable passes through an
intermediate lever (to increase the force of the pull); this
force is then split evenly between the brakes by an equaliser.
Typically, a mechanical lever is added to the existing disc
or drum brakes on the car. In drum brakes, the handbrake cable
runs directly to a lever on the brake shoes. In disc brakes an
additional lever and corkscrew is added to the existing calliper
piston. When the handbrake is pulled, the lever forces the
corkscrew against the piston.
cables can also be used to open the bonnet / hood catch from the
bonnet lever inside the vehicle or connect the gear drive to the
types of Control cables are:
Bonnet and boot cables, as well as tailgate (endgate) cables.
These can also be used to open the bonnet / hood catch from the
bonnet lever inside the vehicle. Tailgate cables are sturdy
cables which connect the ends of the tailgate to the vehicle,
ensuring the vehicles end gate does not open too far.
