Astra: fit for mining and construction

The Iveco brand associated with extreme on/off-road applications and fully off-road quarry and construction work presents its full range for the first time ever at Bauma.

HHD9, the latest in heavy duty solutions

The super heavy duty Astra HHD9 8x6 tipper chassis makes its world premiere on the stand featuring a 63 tonne GVW. This machine is ideal for mining applications, sporting the FPT Industrial Cursor 13 engine rated at 480 HP (353 kW) and the Allison 4700 fully automatic 7-speed transmission.

The technical solutions adopted on this model contribute to an increase in the robustness, reliability and durability of the product, thus enhancing productivity. These solutions include: heavy duty Kessler axles with reinforced front and rear parabolic suspensions; new front disc brakes for a better steering angle and reduced maintenance costs and time; a heavy duty reinforced chassis made of two flat and parallel side members (320 x 90 x 10mm) with the highest Rail Bending Moment among competitors for greater stability and resistance in the most difficult working conditions.

The cab is made with galvanised steel and has been completely re-designed to reflect the aggressive and original identity of Astra vehicles. The engine hood is prominent with rounded lines. It opens completely along with the deflectors for fast and easy access to maintenance areas.

The HHD range also includes the 6x6 model in chassis and tractor versions for a 50 tonne GVW at 70 km/h and a GCW from 120 up to 250 tonnes, depending on the configuration of the truck.

The almost limitless possibilities to customise the truck (short/long cab, a wide range of gearboxes and configuration options) allow for the realisation of a perfect product fit for specific requests coming from different sectors, from logging to heavy construction, from mining to off-road heavy haulage transportation, to Oil and Gas.

ADT 30, a powerful and reliable dump truck

The indoor exhibition area also hosts the ADT 30, a representative of the Astra Articulated Dump Trucks family. This vehicle is fitted with the FPT Industrial Cursor 10 engine, certified for the Tier 3 non-road machinery exhaust emissions standards and rated at 260 kW. The drive is provided by a fully automated ZF transmission for a 6x6 drive arrangement with fully powered chassis steering. Outstanding mobility, power and reliability are the key features characterising this truck which works entirely off-road with a payload of over 28 tonnes (31sht). The vehicle’s ideal battlefields are the most inaccessible places characterised by mud and uneven terrain.

The cab complies with the ROPS (Roll Over Protective Structure) and FOPS (Falling Objects Protective Structure) standards and is designed around the operator with particular attention to driving comfort and visibility. The productivity of these vehicles must be guaranteed at top levels at all times. For this reason, all of the adopted technological solutions aim at cutting routine and supplementary servicing times: the bonnet is electrically operated to make checking and servicing easier. Even the "gull-wing" front wheel mudguards open fully to ensure the best possible accessibility to mechanical parts under the cab, which can be tipped leftwards by 53 degrees.

The ADT range includes many customisation options according to need: an extra strength body for haulage of rocks or heating for easily dumping material in particularly cold climates. A chassis cab version of the ADT30 model is available for special body configurations, such as tanks, lumber transport beds or even laying concrete.

RD32, simple structure, stronger results

A RD32, Rigid Dump Truck, is displayed on the Case Construction stand in the external exhibition area, completing the off-road truck offering from Astra. The driveline of this model features the FPT Cursor 10 engine, compliant with Tier 3 standards rated at 381 HP (280 kW) coupled with a fully automatic Allison 4560 transmission, 6 speeds forward + 1 reverse.

The typical mission for this type of machine is the transportation of materials from a blasting site to a crusher in a quarry or large excavations for heavy construction (dams, roads, etc.).

The simplicity of the vehicle, manufactured with high-strength steel with two boxed chassis rails, combined with the robustness of its components allow for maximum productivity: long maintenance intervals, high reliability and minimal downtime. The front and rear suspension system is designed to ensure maximum driving comfort: independent steering wheels and hydro¬pneumatic suspension cylinders on front end and fork with a Panhard rod on the rear to allow adequate suspension travel on the roughest terrain, while the two hydro-pneumatic cylinders positioned behind the axle provide excellent vertical damping.

The ROPS/FOPS standard compliant cab, positioned on the left, is soundproof and thermally insulated. It is made of steel and features large windows which extend into the lower part of the door to ensure optimal visibility. All instruments are arranged ergonomically around the operator and are easy to use for a complete control and monitoring of the vehicle’s functions.
