Develon Launches New Demolition Excavator, DX245DM-7

Published: 16/6, 2023

DEVELON, formerly Doosan Construction Equipment, has launched the new DX245DM-7 high-reach demolition excavator, replacing the previous DX235DM-5 model.

Powered by the DL06P Stage V diesel engine providing 173 hp (129kW) of power at 1800 rpm, the 31t DX245DM-7 also features a high-visibility, tiltable cab, particularly suited to high-reach demolition applications and offering a 30-degree tilting angle. Another key feature of the DX245DM-7 is a modular boom design and hydraulic lock mechanism on the machine. This provides the customer with a complete, flexible solution that allows them to use the same excavator for other applications on site as well as demolition.

The innovative design ensures it is a simple process to change between a demolition boom and an earthmoving boom to accomplish different types of work on the same project. A special stand facilitates the boom changing operation, which is based on quick-change hydraulic and mechanical coupler connections. A cylinder-based system is used push the locking pins into place to help complete the procedure.

The multi-boom design also allows the earthmoving boom to be mounted in two different ways, which with the demolition boom, provides further flexibility with a total of three different configurations for the same base machine.

A 60-ft (18m) demolition boom allows the machine to work with a demolition attachment to a maximum height of nearly 53 ft (16m). The recommended maximum combined weight for the attachment and quick coupler in this mode is 2.5t.

When equipped with the digging boom in the straight configuration, the DX245DM-7 can work to a maximum height of more than 31 ft (9.8m). In this format, the recommended maximum weight for the attachment and quick coupler is 3.3t. Using the digging boom in the alternative bent configuration, the DX245DM-7 can work with an attachment to a maximum height of 26.2 ft (8m). In this mode, the recommended maximum weight for the attachment and quick coupler is 3.3t.

The DX245DM-7 has a hydraulically adjustable undercarriage, which extends to a maximum width of 12.3 ft (3.74m) to provide optimum stability when working on demolition sites. The width of the undercarriage can be retracted hydraulically to 8.3 ft (2.54m) in the narrow width position, which is ideal for transporting the machine. The mechanism is based on a permanently lubricated, internal cylinder design which minimises resistance during the movement and helps to prevent damage to the components.

Like all DEVELON demolition excavators, standard safety features include a FOGS cab guard, safety valves for the boom, intermediate boom and arm cylinders and a stability warning system.
