Constructora de Obras Públicas San Emeterio (COPSESA) has added a new Develon DX255LC-7 excavator to its fleet, reinforcing the company’s commitment to efficiency, reliability, and innovation in public-works projects across northern Spain.
Founded more than 35 years ago in Cantabria, COPSESA is a family-owned firm specialising in civil engineering, hydraulic, building and earthwork projects. With over 150 employees and a dedicated technical team, the company maintains a strict renewal policy for its heavy machinery — replacing equipment before reaching 15,000 operating hours to ensure maximum uptime and performance.
As part of that policy, COPSESA has replaced a Doosan DX255LC-5 excavator with a 25-tonne Develon DX255LC-7, supplied by distributor Adal Maquinaria. The new model retains the robust reliability of its predecessor while introducing enhanced comfort, fuel efficiency, and hydraulic versatility through its Stage V DL06V engine, D-Eco Power system, and SPC3 controls.
“Our operators feel comfortable with Develon equipment and appreciate the reliability,” said Francisco Javier Ceballos, head of COPSESA’s Machinery and Earthmoving Department. “We know these machines can work beyond 15,000 hours, but our philosophy is to keep the fleet in perfect condition. Develon has always delivered that confidence.”
Currently, the DX255LC-7 is operating on a strategic project connecting the S-10 and S-30 motorways in Cantabria — a development that includes a 619-metre viaduct, extensive embankments, drainage and environmental restoration. The excavator’s hydraulic system allows it to handle diverse tasks such as foundation excavation, rockfill placement, and pile-capping operations with precision.
Operators have reported improved visibility, smoother hydraulic control, and reduced fuel consumption. The ability to manage hydraulic flow directly from the cab — eliminating manual adjustments — has streamlined tool changes between hammers, grapples and demolition attachments.
COPSESA continues to rely on Develon and its local distributor Adal Maquinaria for full maintenance, spare-parts support, and custom branding of its fleet, which also includes DX350-7, DX235LCR-7, DX85R-7, DX62R-7 and DX160W-7 models.
