Linde Material Handling-North American Corp.'s new RX60 series of electric counterbalanced sit-down lift trucks are available in eight models with capacities ranging from 5000 to 10,000 lb (2270 to 4535 kg). The RX60-25C and RX60-30C feature cushion drive and steer tires, while the six remaining trucks in the series have SE drive and steer tires as standard equipment.

Linde's design team engineered a new rail that contributes to a strengthened mast and limited deflection, resulting in improved residual capacity. A travel speed of 12 mph (19 km/h) and lift speed of 100 ft/min enable the trucks to do a comparable job as engine-powered units. The trucks feature automatic power boosts, activated when the system sensors demand, to negotiate railroad crossings, curbs, steep ramps, or other obstacles.

Also on designers' minds was ergonomics, with the RX60 designed to minimize strain on the operator throughout the work day. The trucks feature low noise levels (68 dBa), a floating operator compartment, tilted floorboard, fully adjustable suspension seat, and adjustable steering column.

All components and assemblies are tested to meet rigorous longevity standards, including a heavy-duty cast ductile iron steering axle; major electrical component placed inside the counterweight, which dissipates naturally occurring heat during operation; and thermal protectors that monitor components and limit power output in case of high temperature.

The 80-V electrical system has maintenance-free enclosed motors and is claimed to provide performance comparable to LP and diesel-powered forklifts. Large battery compartments  accommodate standard and vented batteries. A fast-charge assist is also available as an option.

Improved visibility of the load and through the mast—a key element for forklift safety—is accomplished via a unique rail design and with two free-lift cylinders instead of one, which translates into overall improved field of vision. Additionally, all performance parameters are adjustable to adapt to different operating conditions and customer requirements. The “ramp start assist” function helps the operator with stopping and starting on inclines.

Linde says both indoor and outdoor operations are easily handled by the RX60. When equipped with full cab and electric heater, the RX60 functions in inclement weather like an engined truck. On the other hand, fitted with cold storage equipment, it will also work in freezers with temperatures as low as -20°F. The use of the dual front tires adds additional stability for wide loads or at high lift heights.

The machine's energy return system can extend battery life by up to 15%, and energy use is limited and component life extended because all high-voltage components are mounted to the counterweight. Exclusive Blue-Zone memory adaptive software maximizes truck efficiencies based on individual operator driving characteristics, resulting in additional energy savings of up to 20%.

The RX60 has extended 1000-hour maintenance intervals. Design features such as automatic deceleration, dual independent CAN bus control systems, maintenance-free brakes, and continuous onboard diagnostics make it even easier to maintain working conditions. The 3-phase AC system operates without brushes and is completely sealed, extending component life and reducing maintenance expenses.
