TA9 & TA10 Dumper 0803-2 November 2009 5-2
General Description
This range of site dumpers have been designed to provide the greatest degree of component standardisation possible, thus providing
the user with simplified servicing requirements.
This section of the manual must be read in conjunction with the Safety section located at the beginning of the manual.
Skip
All models in the range are 4 wheel drive dumpers having a load
carrying skip located over the front axle, and ahead of the
driver.
Engines
Engines on all machines are Perkins multi-cylinder diesel.
All machines are fitted with electric starting of the engine.
A separate key operated start switch is provided and is located
adjacent to the steering wheel.
A battery isolator switch is provided in engine compartment.
Chassis
The chassis of the dumpers is of the two part articulating type
having a centre pivot joint which articulates in both vertical, and
horizontal planes.
Steering
Steering of the dumper is by an 'Orbitrol' hydrostatic steering
unit, powering a single ram connecting the front and rear chassis
units.
Hydraulic power is supplied via an engine driven pump to the
steering unit, which on turning the steering wheel meters oil to
the steering ram and thus provides movement in either direction
of the vehicle.
In the event of a hydraulic failure the vehicle can still be steered.
Under these circumstances steering loads are high and the
dumper should only be driven at slow speeds.
Transmission
The transmission of the dumpers have torque converters and
PowerShuttle four speed gearboxes.
Brakes
The vehicle braking is provided by means of totally enclosed oil
immersed brakes located within the drive axles. These brakes
are self adjusting, multi-plate discs which are hydraulically
operated by means of a tandem master cylinder. This provides
the feature of totally independent front and rear systems. In the
event of failure of one system, braking will still be available on
the alternative axle.
Handbrake
The vehicle is fitted with an overcentre type handbrake.
Electric System
All models are available with full lighting to comply with EU/
ISO road traffic regulations.
ROPS
Machines are fitted with a ROPS (Roll Over Protective
Structure) to protect the operator should the machine turn over.
