EvoQuip launched the Cobra 290R crusher at the recent Hillhead Exhibition in the UK. The Cobra 290R builds on the success of the Cobra 230. The compact impact crusher provides the perfect solution for onsite recycling in urban areas and is easily transported from job to job.

Ready to crush in minutes as a result of ground level set up and intuitive two button start up sequence, the Cobra 290 is a versatile and easy to use impact crusher that can operate in the demanding applications including reinforced concrete, recycled asphalt, construction and demolition waste, coal and natural rock. The Cobra 290 has been working in a Limestone application at Trotters Quarry in Ireland. Richard Trotter, Managing Director, said “The Cobra 290 really has surpassed expectations. Don’t be deceived by size as while the machine itself is compact in size, it punches way above its weight and I was really impressed with output”

With throughput potential of up to 290tph (320 US tph) depending on feed material and apron setting, the Cobra 290 uses a 315Hp Volvo Engine to power the fuel efficient and high performing direct drive system and has quickly established itself as a force to be reckoned with in the compact crushing sector.

At the heart of the Cobra 290 is the Terex CR055 Impact Crusher with a rotor size of 1000mm (40”) x 1034mm (41.5”). This impactor has been developed using proven components and technology from some of our larger impactors within the Terex range.

Fitted as standard is a hinged inlet lid which greatly reduces the risk of material bridging at the feed in point. Like the Cobra 230 crusher, the Cobra 290 also has two independent hydraulic controlled aprons which allow the operator to optimize the material throughput and reduction. The patented hydraulic overload protection system used not only protects the crusher in the event of an uncrushable piece entering the chamber but it 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 the customer can choose between the full length conveyor design and the vibrating underpan feeder, which offers complete belt protection in heavy duty recycling applications.

The excellent 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.

The Cobra 290 was designed with the operator in mind in terms of ease of use and serviceability with ground level access to the engine, hydraulics, service and refueling points. This is further enhanced with features such as the hinged radiator pack, hinged diesel tank and product conveyor that can be removed quickly for major maintenance. In addition the operator has the ability to move the machine using the remote control from the excavator cab. This can be done without shutting down the Crusher.

There is an option for a single deck afterscreen system. This incorporates an aggressive 2,74 m x 1,5 m  (9’ x 5’) screen which provides the customer with a sized end product. The ability to quickly detach the complete afterscreen system, including the oversize conveyor, provides the customer the option or running the machine in standard mode or to transport it separately. It is possible to purchase and retrofit this option at a later date.
