The 20-t (22-ton) weight class EW230C from Volvo Construction Equipment is built around a new, more robust platform, which is designed to ensure the stability needed to manage bigger loads, for heavy lifting applications such as laying big pipe for drainage projects, or hard digging.
VCE says that one of the benefits of the platform is that its design ensures that the rear axle weight, when fitted with the standard counterweight, is below 12 t (13 ton). A heavier counterweight is also available for applications not requiring the machine to be moved on the road.
With the light counterweight, the EW230C weighs 21.6 to 24.3 t (23.8 to 26.8 ton), depending on machine configuration, and 23.1 to 25.6 t (25.5 to 28.2 ton) with the heavier counterweight. A choice of 18.7-ft (5.7-m) mono or two-piece boom is available.
The EW230C is powered by a Volvo D6E EHE3 diesel engine that develops 125 kW (167 hp) net at 2000 rpm. When it's required for mass excavation work or heavy lifting applications, VCE says the EW230C has a lift capacity among the best in its class.
Access to the superstructure via steps provides for easy servicing and routine maintenance checks to minimize downtime. The machine features a new and higher capacity cooling module and a load-sensing hydraulic system with two pumps—one for the attachment and travel and a second, closed-loop slew pump.
It was designed with the slew ring from the larger EC240C for increased strength and durability in tough working conditions, and its digging forces are 10-15% greater than on the EW210C.
