Volvo Construction Equipment has launched its new EC550E T3 excavator in Asia, offering tonnes per hour production close to a 70-t-class machine but with lower fuel consumption.
Thanks to its buckets and fast cycle times, the EC550E delivers 35% greater production than the 50-t-class EC480D in typical dig and dump applications. In fact, its production levels approach those of a 70-t-class machine, said Volvo.
The larger bucket is enabled through the increased undercarriage dimensions (for greater stability), as well as upgrades to the frame, boom and arm. The fast cycle times, meanwhile, result from the engine’s high torque at a remarkably low rpm combined with the large displacement pumps.
According to Volvo, the EC550E’s dimensions, lifting capacity and engine are well in line with some competitor 70-t-models, but it consumes considerably less fuel. In addition to the efficient engine and electrohydraulic joystick commands, the EC550E has the industry’s most high-performing hydraulics.
The EC550E is the first excavator to use Volvo’s pioneering independent metering valve technology (IMVT). Instead of a conventional spool-type main control valve (MCV), the machine uses dedicated valves – for feed and return for each actuator.
Oil is pumped exactly according to demand at any given moment to eliminate hydraulic losses and deliver an extreme level of fuel efficiency with excellent controllability.
Furthermore, the EC550E can fill an AG35 or AG40 hauler with four to six buckets. This means that Volvo now offers two perfect match excavators for A35G or A40G haulers in Asia – the EC750D and the EC550E, depending on customers’ productivity and efficiency needs.
Using Volvo Site Simulation, the local dealer can recommend the best fleet and site set-up to maximise productivity and efficiency. Meanwhile, fuel efficiency reports and operator training can help reduce fuel expenditure further.
