Develon expands demolition excavator range

Develon launches new DX140RDM-7 demolition excavator in Europe

Develon has launched the new DX140RDM-7 to the European market; the latest addition to the company’s range of demolition excavators. Like the three larger models from 31 to 61 tonnes, the new DX140RDM-7 22.5-tonne demolition excavator offers multiple configurations to choose from, providing the customer with a range of solutions depending on the project to be completed, including a multi-purpose version that can be used for other applications on site as well as demolition.

A ‘Monolithic’ variant unique to this model features only a demolition arm without any interchangeability. Alternatively, like the larger machines, the DX140RDM-7 is also available in a dual format utilising a modular boom design and hydraulic lock mechanism, allowing the user to change between different arms for demolition and digging using the same machine.

In the fixed ‘Monolithic’ version of the new DX140RDM-7, the machine can work with a demolition attachment to a maximum height of 16m. The recommended maximum tool weight in this mode is 1,450kg.

In the dual-purpose version of the DX140RDM-7, the pin height and maximum tool weight are 14m and 1,450kg, respectively (with a 2m extension as an option).

A special stand is provided to facilitate the boom changing operation, which is based on quick-change hydraulic and mechanical coupler connections. A cylinder-based system is used to 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 dual-purpose base machine.

The DX140RDM-7 has a hydraulically-adjustable undercarriage, which extends to a maximum width of 3.7m. The width of the undercarriage can be retracted hydraulically to 2.5m in the narrow width position for transport. The mechanism is based on a permanently lubricated, internal cylinder design that minimises resistance during the movement and helps to prevent damage to the components, Develon says.
