Coal Handling

Hit your Coal Goals

Dressta’s large dozers are routinely chosen for use in challenging coal handling applications that run 24/7, such as power, generation and steel production. These machines are tailored to excel, with a range of features specifically designed for these challenging environments.

Without durable, efficient dozers that are productive throughout a long work cycle, coal supply can grind to a halt and cause operational outages. Dressta can help advise on the optimal performance specifications and machine modifications, with our Special Feature Requests helping to meet the specific criteria your business needs.

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.

Specialist Attachments

Equipped with high capacity coal blades, Dressta dozers move large quantities of coal with ease. They can be specialized with heavy-duty undercarriages featuring excellent shock absorption characteristics and a low centre of gravity to optimize stability when working on slopes.

With a wide range of blades, rippers and track shoe options, Dressta can expertly modify the machine to optimize productivity in the work you do.

Steering Precision

Dressta coal dozers provide superior steering control and traction. This allows them to operate with large loads, even on the sloped sides of a coal stockpile – where other types of coal handling equipment are typically not assigned.

Designed to Last

Proven to operate for over 4000 hours in coal applications per year, Dressta dozers are equipped with special guards and the protections necessary to maintain optimal performance in these abrasive and dusty conditions.

Dressta dozers are equipped with a Turbine Type Precleaner, which uses centrifugal force to eliminate coal dust from the air, thus prolonging the life of normal filters and improving fuel economy and engine life.

Operator Comfort

Our coal dozers are extremely safe and entirely comfortable for the operator, with a spacious 6-sided cab that features 2-post ROPS and panoramic visibility of the environment.

The sealed operator’s cab is equipped with A/C and air recirculation systems, with hot and cold air generated as required. Overpressure inside the cab prevents coal from entering, allowing the operator to breathe clean, and fresh air in spite of the outdoor environment.

Quality Undercarriage

The heavy-duty undercarriage is made from a high-strength, steel-fabricated structure that allows shocks to be transferred from the ground to the mainframe, protecting drive train components from damage in abrasive conditions.

 

Machines Engineered for Coal Handling

Optimal power to weight ratio for unrivalled traction & drawbar pull…

The TD-25R Extra 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-25R Extra 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-25R Extra 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.
  • The Full-U Blade provides high volume movement of light non-cohesive materials such as coal and woodchips.
  • Coal Blade for excellent coal pile productivity. Its length, height, and wing angles were developed specifically for high production coal dozing. The blade pocket is in the right place to deliver a live, rolling load. Extended end plates help contain loads and eliminate side spillage.
