In response to customer demand, Dressta is delighted to unveil the new TD9 Hydrostatic Crawler Dozer. This new high-performance, compact crawler dozer has been developed by Dressta’s team of expert engineers, and is the first of three new world-class models that range from 74 to 101 Net HP.
The new model has been validated by expert operators at a series of pre-launch performance trials at the Dressta proving grounds in Poland. The TD9, due to be launched in the third quarter of 2015, was presented to equipment owners and dozer operators from the key markets of North America and Canada. They put the Iron to the test in a series of challenging trials designed push the performance of the new hydrostatic dozers to the limit, and provided their feedback to help fine-tune the machine’s performance.
“The operators’ input in regards to ergonomics and command of control played a key role in refining the design. As a result, the low-effort controls for the blade and dual path hydrostatic drivetrain deliver the required response in all applications of machine performance.” said Howard Dale, Global Vice President of Sales at Dressta.
The key components of the new models are from worldwide renowned suppliers such as Cummins, and Rexroth, while the structural design and DNA are a natural progression of Dressta’s decades of experience in building crawler dozers and other construction equipment.
Optimal Power & Fuel Efficiency Delivered by Cummins Tier IV Final Engine
The three models are equipped with Cummins Tier IV Final engines and cover a horsepower range of 74 to 101 Net horsepower. This innovative engine technology features ultra-clean aftertreatment systems while simultaneously providing excellent fuel efficiency.
Power, performance, reliability and durability are the critical factors for the power unit in a crawler dozer. With the Cummins Tier IV Final engine, the new Dressta models meet these criteria comfortably, with the additional benefits of, enhanced productivity and a reduction in overall operating costs.
Dual Path Hydrostatic Drive Delivers Maximum Productivity
Dressta’s variable bi-directional dual path hydrostatic drive is controlled by a programmable electronic control module. This provides the perfect match between load and ground speed, regardless of the ground condition or specific dozing application. The result ensures that operators have full command during the most challenging of tasks, such as when dozing with a full load or performing precise final grade operations.
The operators have the ability to adjust the presets of the tractor to meet the requirements of the task at hand. They can choose to programme variables such as forward to reverse speed ratio, or enable ‘Power’ ‘Normal’ and ‘Economy’ modes depending on the job conditions. The versatility to choose between different modes and the flexible speed control provide both enhanced productivity and excellent grade accuracy.
Independent track control delivers the required speed changes to each side and allows for smooth, full-power turns. On-site maneuverability and job performance are further strengthened by the stable counter-rotation feature, whilst the low centre of gravity delivers stable and safe operation when working on slopes or in rugged terrain.
Safe & Comfortable Cab for a Fresh & Productive Operator
The ergonomics of the cab and an intuitive, highly-responsive control system make operating the new TD9 a delight for the operator. Dressta understand that the ease of command and control creates a better working environment and thus increases productivity.
A newly designed ISO-mounted operator cab with positive pressure features a comfortable interior space that is protected by a robust external ROPS for optimal safety. A fully adjustable operator seat provides the user with ample leg room and ease of access to all controls.
The cabin’s large glass windows provide excellent for-and-aft visibility to the outside environment, blade corners and rear of the tracks – an essential requirement for compact machines in terms of both safety and productivity.
Control grips have been designed so that the user can comfortably operate the machine for hours, and are designed for the ease of operation whether wearing heavy gloves or not. The hand wrap controls are designed to reduce the risk of the operator’s hands slipping from the levers, particularly when working in hazardous environments such as on steep slopes – a further example of Dressta’s attention to detail in risk reduction.
The new heating and air conditioning system features multiple vents to provide large volumes of fresh air quietly and efficiently in order to maintain the operator’s desired working temperature.
But as well as providing a comfortable internal environment, Dressta has developed the machine to be highly responsive to the operator’s wishes. Ensuring the crawler dozer performs as a mechanical extension of the operator’s skill was an essential consideration in the design. In achieving this, the hydraulic controls have been tuned to perform seamlessly at the command of the operator so they can perform long hours of fatigue-free usage.
For the additional benefit of the operator, the machines are supplied both GPS and Trimble-ready to help them achieve the requirements of any given task.
Complete Machines Built with the Operator in Mind
Dressta’s new range of compact dozers are designed to exceed expectations in a range or applications, from power dozing and site preparation, to landscaping, final grade and fine-finishing jobs around houses.
This has been achieved through Dressta’s willingness to proactively seek customer feedback and implement the responses directly into the design & validations process. The team of engineers features experts in a variety of applications, who have masterminded the perfect blend of intuitive functionality, extreme durability and ultimate operator comfort in a compact crawler dozer.
