Yale ERP15-20VT: Europe’s most energy efficient electric forklift

Yale® has announced a change to the specification of its 3-wheel ERP15-20VT series, which makes this the most energy efficient electric forklift truck available in Europe.

Yale expects energy consumption to become an increasingly important consideration in materials handling as even small savings add up to substantial cost reductions and productivity improvements over the course of a week, a month or a year.  

To achieve market leadership in energy efficiency, Yale has replaced the previous hydraulic service brake system with ‘E-braking’, which uses the regenerative braking principle. The brake pedal position is monitored by a sensor whose voltage output determines the amount of braking torque provided by the motors. Yale’s E-braking system is self-calibrating and requires no maintenance.  

The truck’s parking brake system operates independently of E-braking and still features Yale Stop™ functionality. This automatically applies the parking brake whenever the truck is stationary and traction has not been requested.  In addition to E-braking, Yale has introduced E-steering to the truck as another way of recycling energy. Both energy-saving features are now included as standard on the ERP15-20VT 3-wheel truck.  

In addition, the introduction of E-braking to Yale’s ERP16-20VF has made significant energy savings. The 1.6 tonne, 4-wheel, medium wheelbase model now has an energy consumption figure of 4.4 kWh/h.  Everything else remains unchanged, with all models benefiting from Yale’s ‘e-Balance’ approach which allows businesses to achieve the right blend of performance, manoeuvrability and battery shift life for each application. Two performance modes - HiP (high performance) and ECO-eLo (energy low) - can be selected to suit the application or the operator, and additional settings can be applied by a Yale technician.

Welcoming the improvements, Karen Calver, Yale product manager for electric counterbalance trucks, says: “With their energy efficiency and best-in-class manoeuvrability, these trucks have always helped customers to increase throughput and reduce the cost per pallet moved. Now their economy is even better and, in the case of the 3-wheel truck, officially unbeatable.”
