Volvo Construction Equipment (Volvo CE) has unveiled two new compact excavators for North America: the 3.5-ton EC37 and the 4-ton ECR40. These models replace the EC35D, ECR35D and ECR40D.
“The 3- to 4-ton size makes up more than a quarter of the compact excavator market in North America, and we’re excited to refresh our offering in that range,” said Darren Ashton, product manager — compact equipment, Volvo CE. “I think our customers will be very happy with the improvements we’ve made based on their feedback.”
This duo shares the same platform and components, though the EC37 excavator has a conventional upper carriage design and the ECR40 excavator has a short swing radius to allow for work in more confined spaces.
Control
The new EC37 and ECR40 excavators give operators an accessible cab. It provides visibility thanks to slim corner pillars and wide, flat glass areas. The armrest and controls float with the seat, and the door opening and travel pedals are larger than in previous models.
The intuitive jog wheel and HMI (human machine interface) functionalities provide controllability and adaptability for various job requirements. Work modes now include an ECO mode and an auto engine shutdown in addition to the existing auto engine idle. With auto engine shutdown, hours not worked are excluded from recording.
Hydraulics
Customizable hydraulics flow settings and work modes enable the use of different attachments to match specific applications.
“The load-sensing hydraulics are definitely a highlight,” said Ashton. “The way the controls are set up and the smooth movements are just outstanding, and it all works together for better fuel efficiency.”
If there are multiple operators working with the same machine, each person can set up the controls however they see fit with setting changes on the new 5-in. HMI.
Versatility and Stability
The EC37 and ECR40 include a new elongated undercarriage for stability due to weight balance provided by long contact between the tracks and the ground. The adjusted center of gravity reduces the “rocking chair effect”.
The counterweight has been standardized across these two models and the ECR50 and ECR58 excavators to simplify component needs for fleets with multiple models. Optional features include a float blade and LED work lights.
Maintenance
These new machines feature 50-hour greasing intervals and a fuel tank capacity of 18.5 gallons. The patented multifunction hydraulic oil filter protects the hydraulic system. The engine and rear hoods feature wide openings, and the engine doesn’t require a diesel particulate filter.
