Ship Trimming

Clear the deck

Dressta dozers make light work of ship trimming applications and have become the preferred choice of ports throughout the world. The dozer is lowered into the vessel to trim the bulk and square off the hatch so that the wharf grabs can operate at full capacity.

These machines are equipped with a two-way blade designed to push and pull materials such as grains and fertilizer to the working area of the unloading grab. A range of features to help them excel in these environments.

For specific features that would enhance the machine’s ship trimming performance, you can make a Special Features Request (SFR) for truly bespoke equipment, including:

  • Lifting / Craning Points
  • Self-Cleaning Track Shoes
  • Spark Arrest Muffler
  • Reversible Fan
  • Cyclonic Air Cleaner
  • Fire Suppression System

Take a look at why our dozers are ideally suited to ship trimming applications.

Hydrostatic Steering

Dressta dozers are built with reliable hydrostatic steering, offering both flexible and precise handling in compact ship holding spaces. The hydrostatic functionality enables smooth steering at any engine speed and allows precise control when pushing or pulling materials.

Maximum Operator Comfort

All Dressta machines are built with efficient heating and air-conditioning systems to maintain the desired working temperature and allow the operator to work at ease, especially in the hot and dusty conditions often found in ship trimming applications.

Longevity

Dressta dozers’ ring-type sprockets distribute wear evenly over track bushings and are replaceable without removing the track frames. The Lubricated Track System (LTS) eliminates internal pin and bushing wear through the use of a patented seal assembly. The split master link reduces chain removal and installation time.

If you cannot find the model below with the appropriate engine configuration (Emission Levels: Tier 3, Tier 4 Interim, Tier 4 Final) for your region, please email us or contact your local dealer.

 

Machines Engineered for Ship Trimming

Optimal Long Tracks (LT) for high performance traction, ripping and dozing in hard ground …

The TD-15M Extra LT sets the standards for others to follow and is a result of DRESSTA’s experience in designing highly efficient and productive Crawler Dozers.

Design concepts utilised in the TD-15M Extra LT include, optimisation of weight distribution, modular construction, and use of a one-piece main frame, two-speed Steering Drive and a 3-point track mounting system. Optimal performance is achieved when machine weight is matched to power and the TD-15M Extra LT provides a second-to-none balance of weight for traction and power for unrivalled drawbar pull.

Features & Benefits

WORKING EQUIPMENT
Blades

  • Standard Semi-U Blade design combines the penetration ability of a straight blade with the increased capacity provided by short wings. It is used for heavy duty applications such as mining and road construction.
  • Angle Blade with tilt is ideal for side casting, backfilling, cutting ditches or setting a final grade by reducing the amount of manoeuvering required to do these jobs.

Rippers
Adjustable parallelogram multi-shank ripper offers excellent 455 mm (17.9”) penetration in extremely tough materials and can be used with up to 3 shanks adjusted to two vertical positions. The single shank ripper option offers a deeper penetration of 713 mm (28”).


ENGINE
The TD-15M Extra LT is powered by a diesel engine that delivers outstanding power & torque;

  • Heavy Duty Cummins QSC 8.3 litre Tier 3/EU Stage IIIA Diesel Engine.
  • Direct injection, in-line, 6 cylinder, 4 stroke, turbocharged & Charge Air Cooled (CAC) engine developing 142 kW (190 hp) Net at rated engine speed of 1950 rpm


TRANSMISSION
Transmission system that automatically matches speed to load conditions for optimal push power, preventing driveline shock, multiplying the torque required while delivering 6 forward and 6 reverse speeds.

  • Torque Converter
  • 3-Speed Powershift Transmission
  • 2-Speed Steering Drive
  • Double reduction Final Drive

The modular design drivetrain incorporates the engine, torque converter, transmission, steering drive and final drives. Components can be easily removed & re-fitted without oil loss ensuring maximum machine uptime.


HYDRAULICS
A proven design multiple pump system & high capacity hydraulic reservoir for improved cooling. Hose & tube routings are accessible and yet well protected to prevent accidental damage. Trimble ready option is available on factory build orders.

Two-speed steering module on Dressta dozers maintains power to both tracks – at all times. You get the benefit of vastly improved traction to push loads effortlessly through turns, quickly and smoothly.


CAB - OPERATOR STATION & CONTROLS
Deluxe 6-sided ROPS / FOPS Cab with enlarged glass area provides a clear and direct line of sight to both the blade and ripper. The comfortable, sound-suppressed, pressurised cab is equipped with:

  • Efficient air recirculation system
  • Air conditioner & heater with multiple vents
  • Deluxe air suspension seat with adjustable arm rests. The seat swivels 14 degrees to the right for better ripper viewing
  • Ergonomically design joystick controls for direction, blade and ripper operations.


ROBUST FRAME AND UNDERCARRIAGE
DRESSTA Mainframe and Track frame system ensures excellent machine balance for dozing, ripping, or final grading applications.

  • Mainframe – a one-piece weldment consisting of the front frame, rear frame, and equaliser bar. The rugged design of the mainframe absorbs impact shock loads and twisting forces to ensure a long life.
  • High quality sealed and lifetime lubricated track rollers
  • Heavy-duty idlers and track tensioners

Tracks – High quality durable tracks for tough working conditions;

  • Track Chain - Links made of drop forged steel alloy and strutted to resist twisting and working stresses.
  • Track Shoes - Wide range of track shoe widths helps to match TD-15M Extra LT perfectly to all types of ground conditions.
  • Dressta Lubricated Track System (LTS)

Track Chain Guides and Track Roller Guards – Track chain guides are standard equipment and full length track roller guards are optional.

Suspension System – 3-point suspension system consisting of two pivot shafts and equaliser bar.
