EvoQuip Cobra range continues to grow

Company launches the compact and versatile Cobra 290R impact crusher at Hillhead 2018

Hillhead 2018 saw the launch of the EvoQuip Cobra 290R impact crusher. Building on the success of the Cobra 230, the compact Cobra 290R is well suited to on-site recycling in urban areas and easily transported from job to job.

Ready to crush in minutes thanks to its ground-level set-up and intuitive two-button start-up sequence, the Cobra 290 is a versatile and easy-to-use impact crusher capable of operating in the most demanding of applications, including reinforced concrete, recycled asphalt, C&D waste, coal and natural rock.

The Cobra 290 has been working in a limestone application at Trotters Quarry in Ireland. Managing director Richard Trotter said: ‘The Cobra 290 really has surpassed my expectations. Don’t be deceived by its size; although the machine is compact, it punches way above its weight and I was really impressed with its output.’

With a throughput potential of up to 290 tonnes/h, depending on feed material and apron setting, the Cobra 290 utilizes a 315hp Volvo engine to power its fuel-efficient, high-performance direct-drive system.

At the heart of the Cobra 290 is a Terex CR055 impact crusher with a rotor size of 1,000mm (40in) x 1,034mm (41.5in). This impactor has been developed using proven components and technology from some of the larger impact crushers within the Terex range.

Fitted as standard is a hinged inlet lid that greatly reduces the risk of material bridging at the feed-in point, and like the Cobra 230, the Cobra 290 also has two independent, hydraulically controlled aprons that allow the operator to optimize material throughput and reduction.

The machine’s patented hydraulic overload-protection system not only protects the crusher in the event of an uncrushable item entering the chamber, but also minimizes apron bounce and reduces the amount of oversize material passing.

The tip speed of the rotor can be varied depending on the application and product requirements. Throughout the crushing process, the Cobra 290 constantly monitors the engine load and automatically regulates the feeder speed as required.

Below the impact crusher, customers can choose between the full-length conveyor design and a vibrating underpan feeder, which offers complete belt protection in heavy-duty recycling applications.

The generous clearance from the rotor to the belt; the short distance from the crusher outlet to the magnet; and the ability to hydraulically raise and lower the conveyor all ensure optimal material flow through the machine.

EvoQuip say the Cobra 290 was designed with the operator in mind, in terms of ease of use and serviceability. Ground-level access to the engine, hydraulics, service and refuelling points is further enhanced by features such as a hinged radiator pack, a hinged diesel tank and a product conveyor that can be removed quickly for major maintenance. In addition, the operator has the ability to move the machine via remote control from the excavator cab, without shutting down the crusher.

A single-deck after-screen system is available as an option. This incorporates an aggressive 2.74m x 1.5m (9ft x 5ft) screen that provides a sized end product. The ability to quickly detach the complete after-screen system, including the oversize conveyor, allows the customer to run the machine in standard mode or transport this system separately. This option can be purchased and retrofitted at a later date.
