Develon launch new demolition excavator
Company introduces versatile 22.5-tonne DX140RDM-7 high-reach demolition excavator
DEVELON have announced the launch of the new DX140RDM-7 demolition excavator, the latest addition to the company’s successful range of high-reach demolition equipment.
As with all Develon’s larger excavator models (31–61 tonne), the 22.5 tonne DX140RDM-7 offers multiple configurations for the operator to choose from, as well as a multi-purpose version that can be used for other applications in addition to demolition.
The ‘Monolithic’ variant of the demolition machine allows the operator to work with a demolition attachment to a maximum height of 16m. The recommended maximum tool weight in this mode is 1,450kg.
For versatility the DX140RDM-7 excavator is available in a dual-purpose version, utilizing a modular boom design and hydraulic lock mechanism that allows the user to change between different arms for demolition and digging using the same machine. The pin height and maximum tool weight are 14m and 1,450kg, respectively, in dual format mode.
All the components such as the undercarriage, the tilting cab, and the shoes remain the same as in the fixed Monolithic version – only the modular boom design and hydraulic lock mechanism are different, allowing the user to swap between the demolition and digging arms.
The innovative design of the DX140RDM-7 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 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. In total, there are three different configurations for the dual-purpose base machine.
The DX140RDM-7 features a hydraulically adjustable undercarriage, which extends to a maximum width of 3.7m to provide optimum stability when working on demolition sites. The width of the undercarriage can be retracted hydraulically to 2.5m in the narrow width position for ease of transportation.
Standard safety features of the DX140RDM-7 excavator include: a FOGS cab guard; safety valves for the boom, intermediate boom, and arm cylinders; and a stability warning system.
