Electromechanical actuators for off-highway vehicles

Electromechanical actuators for off-highway vehiclesSKF is launching a new range of electromechanical actuators for off-highway vehicle applications. Designed to increase performance, productivity and profitability, the actuators provide both OEMs and end-users with significant savings in cost and time.

The range has been specifically developed for off-highway vehicles, and fulfils a number of functions on articulated dump trucks, tractors and backhoe loaders. They have been engineered to withstand harsh environmental demands and have undergone extensive trials. In particular, the units are proven to resist wide temperature swings, chemicals, dirt, dust, water, vibration and other demanding operating conditions. Improved robustness brings increased machine uptime and a reduced risk of failure.

Virtually maintenance-free, the actuators help to minimise downtime and cost, while the hydraulic-free actuation eliminates the risk of hydraulic fluid leaks. Capable of operating at temperatures from -40 to +85degC at a 25 per cent duty cycle, the new electromechanical actuators feature robust metal gears and corrosion-resistant IP66 housings. Furthermore, the extensive testing of the units considerably reduces validation time and costs, as well as warranty issues.

Already the new actuators have been applied to lifting and movement functions such as engine hood lifting and ergonomic functions including foot step deployment and door opening/closing control in large vehicles. They have also been used for levelling and height adjustment functions for better workplace convenience and operator comfort.

"Phil Burge, Communication Manager at SKF, comments: With the introduction of our new actuators, we are able to offer OEMs the flexibility they need to design the next generation of more productive, cost-effective, eco-friendly off-highway equipment. Additionally, we can provide a range of engineering consultancy services backed by decades of experience with demanding actuator applications in various industries, to help OEMs create custom solutions."

SKF electromechanical actuators are available in two series: CAHB-20/21 for medium to heavy-load applications; and CAHB-10 for low-load applications.
