Develon completes launch of new ‘DX-7M’ tracked excavator range meant for markets including Middle East

Staff Report,

20 Sept 2023

Comprising 19 models from 2 to 53 tonnes, new machines for Tier 2 and 3 markets see productivity rise of up to 17% and fuel efficiency improvements of up to 32%, with special emphasis on safety and cab comfort

Develon has completed the launch of 19 excavator models as part of the company’s latest generation ‘DX-7M’ range of tracked excavators from 2 to 53 tonnes for Tier 2 and Tier 3 markets worldwide.

The company, formerly Doosan Construction Equipment, said the new excavators are designed for a wide range of markets, from construction, rental, recycling, waste processing and utilities to mining and quarrying.

The models are :-

- DX27Z-7M and DX35Z-7M (2-3t Mini-Excavators)
- DX200A-7M, DX210-7M, DX220LC-7M and DX220AF-7M (20-22t Crawler Excavators)
- DX225LC-7M and DX225LCA-7M (22t Crawler Excavators)
- DX300LC-7M, DX300LCA-7M, DX360LC-7M and DX360LCA-7M (31-37t Crawler Excavators)
- DX400LC-7M, DX450LC-7M and DX450LCA-7M (41-45t Crawler Excavators)
- DX490LC-7M, DX490LCA-7M, DX530LC-7M and DX530LCA-7M (49-53 t Crawler Excavators)

Develon said that from the smallest model in the range, the DX27Z-7M 2.8-tonne mini-excavator, to the largest, the DX530LC(A)-7M excavators, the ‘DX-7M’ models all offer significantly improved performance compared to the previous generation machines. This is due to many enhancements, including more powerful engines and new higher flow hydraulic systems.

The DX200A-7M 20t excavator and all the larger excavators from the DX300LC(A)-7M upwards incorporate Develon’s Virtual Bleed Off (VBO) cutting-edge technology. The VBO system utilises an electronic pressure-controlled pump within a closed centre hydraulic system for productivity increases of up to 17% and fuel efficiency improvements of up to 32%, depending on the model and the mode selected. The closed centred main control valve minimises pressure loss, while the electronic pressure-controlled pump manages and optimises engine power more effectively.

Develon added that improved feedback to the operator through the joystick results in enhanced machine control and less operator fatigue. The acceleration and deceleration of the excavator workgroup functions are smoother, allowing operators to perform repetitive swinging and digging motions with less jerking movements.

Another feature of most of the models from 20t and above that contributes to decreased fuel consumption is the advanced Smart Power Control (SPC) system from Develon. The SPC system controls engine RPM automatically to supply the appropriate torque depending on workload and speed, to ensure the best fuel efficiency.

The completely redesigned cabs on the DX-7M excavators provide maximum comfort and total control of all aspects of the equipment. Several ventilation and air conditioning options are offered to meet any additional needs.

Enhanced safety is also ensured by the seat-belt warning alarm system and the AVM (Around View Monitor) system, which is designed to prevent accidents caused by blind spots.

Other comfort aspects of the new cabs include:

- New interior with a dark grey base for a modern look

- Upgraded heating and ventilation functions for operator

- 8-inch touchscreen monitor for intuitive operation

- DAB audio (hands free, Bluetooth)

- Choice of fabric seat with heating function or leather seat

- Multipurpose cup holder and storage available

- Ergonomic footrest (reduced ankle fatigue)

- LED cab lights

- Rear sun visor

The DX200A-7M and DX220AF-7M models have additional reinforcement for exceptional off-road performance. Develon said that every key component meets its global standards. In the DX200A-7M, the hydraulic components and the engine tank have been strengthened and the robust frames and structures are designed to stand up to the rigours of tough workplaces. Similarly, the DX220AF-7M is fully armoured from top to bottom to help maximise uptime on all types of extreme terrain, including forestry work.
Another important feature of the new generation Develon excavator range is the installation as standard of the latest version 3.0 of the Develon Fleet Management system, which provides a telematics management system, by collecting data from sensors on the machines. In fact, the DX27Z-7M mini-excavator is now the smallest model in the Develon range with the successful Develon Fleet Management system.
