THE 6 HIGHLIGHTS OF THE SERIES 311

DRIVE

Include: 

1. Drive unit: Engine

The soil compactors 311 are driven with a Cummins engine. Advantages:

- Strong power output

- High reliability

- Low fuel consumption

- Conform emission regulation

- Large fuel tank capacity

- Perfect service network of Cummins in India

Engine Features: The machines are equipped with an engine temperature warning alarm as standard.

Other features are:

- Indicator coolant agent (standad) - can be visually checked

- Additional fuel prefilter (option) - recommended for countries with very poor diesel quality (higher water proportion in the fuel).

2. Drive unit: Drum drive

The model with smooth drum is equipped with drum drive as an option. The version with PADFOOT shells is equipped with drum drive as standard.

Climbing ability

3. Drive unit: Axle

- The rear wheel pair is connected and driven via one axle.

- The axle with a limited slip differential prevents the wheels from spinning and/or improve the driving torque of the machine and therefore has advantages in certain situations.

- Starting up in difficult conditions, off-road driving: The differential guides the driving torque from one slipping wheel to the wheel with better ground contact and therefore improves the traction.

- On-centre-feel: A locked axle runs better in a straight line than an unlocked axle.

4. Drive unit: Cooling - system 

- The high-performance cooling system enables the machine to also be operated with high ambient temperatures.

- The one-part cooler is simple to clean and enables an optimal cooling performance in just two stages.

- Utilisation: Possible even under extreme climatic conditions. Temperatures from -20 °C (with cold start kit) up to +55 °C.

- The objective of this cooling system is, along with additional improvements, the achievement of higher utilisation temperatures.

Stainless steel flexible bellows

- Stainless steel flexible bellows: Installation of a stainless steel flexible bellows improves resistance against vibrations

5. Drive unit: Tyres

- The soil compactors 311 is equipped with an industrial tractor tyre.

- Universal tread For smooth drum and padfoot shells.

- For less damage, imprints and marks on the surface area.

- Good to know: The tyre pressure has a considerable influence on the traction.

COMPACTION

1. Compaction: Drum models

- Smooth drum and smooth drum with padfoot shells.

- The drum comes with a dual scraper bar as standard for smooth working conditions in forward and reverse operation. Smooth drum with scraper and smooth drum with padfoot shells and scraper.

2. VIBRATION

- The soil compactors compact with vibration.

- How does vibration work? The drum moves in a circular motion that is induced by a rotating unbalanced mass. This causes impacts on the material and directs vertical centrifugal forces into the subsoil.

- Compaction can occur at large or small amplitudes.

3. Compaction: Parameter

- Frequency idicator (option) - Display for the actual frequency.

- Hamm compaction meter (option) - Measurement and display of the rigidity of the subsoil by utilising acceleration sensors on the vibrating drum.

- Speedometer (option) - Display for the current speed.

- Amplitude pre-selection.

+ Amplitude pre-selection for vibration

+ Big amplitude

+ Zero position.

+ Small amplitude

+ The 311 has two frequencies: Small amplitude - high frequency, Big amplitude - small frequency

4. ICS

The ICS system is available as an option. Advantages:

- Status is displayed on a PC

- Minimizes the number of passes

- Records output.

- Prevents the danger of over-compaction.

- GPS based system

Asia Automation and Plexitech are two different suppliers of ICS. PWD = Public works department. MC = Municipal corporation

ICS comes with these components:

- Vibration sensor

- GPS antenna

- Display (hardware)

- Display (software): Location of the machine, Number of passes, Job site data (length, width), HMV value.

ERGONOMICS

The ergonomics also play an important part with these machines. Here is an overview of the most important features.

1. General features

To provide the driver with best comfort, the series 311 is equipped with appropriate features.

- Access: access from the left side

- Operator's platform: Series 311 machines are equipped with a protective roof and handrails as standard. Rubber buffers isolate the operator's platform from vibration.

- Seat: Driver’s seat of imitation leather, equipped with safety belt and longitudinal adjustable (forward-backward) for individual comfort.

- Storage: Large lockable storage area under the seat (service/tool kit)

2. Ergonomics: Operation

The compactors 311 impress with their simple and safe operational controls. The buttons on the dashboard can be viewed very easily.

- Dashboard: Clear information display. Less operating and control elements with increased functionality. Compact dashboard with international, easy to understand symbols and displays. Roller symbols for easy-to-read representation of the selected functions. Vandalism protection (optional)

- Steering column: Steering column is fixed type, seat is adjustable forward and backward to suit operator reach. There is a 12V power outlet integrated at the left side of the steering column.

- Drive lever: 1 drive lever + 1 throttle lever located on the right side of the driver’s seat (Explore the details by clicking in the hotspots.)

3-POINT ARTICULATION

See more 3-point artculation: AT HERE

- Hamm does not utilise a conventional articulated joint, rather a special construction design: The 3-point articulation

- Uniform weight distribution on the rear axle when turning for excellent traction on rough terrain

- Damping of impacts

- Excellent on-centre-feel

- Increased anti-tipping safety when cornering

- Direct steering thus less steering work for the operator

SERVICE: OVERVIEW
