Nine Units with a Long and Proud Hanix and Schaeff Heritage
The Terex compact excavator line was developed and made by Hanix and distributed by Schaeff in Germany. The first model was called the HR02. Terex purchased Schaeff in January 2002. Terex compact excavators are still engineered and manufactured in Rothenburg, Germany. Through evolution of the equipment, the Terex compact excavator line has seen more than five generations. Terex has nine compact excavator models ranging from 14 to 73 hp with operating weights from 3,600 to 16,535 lbs and a variety of attachments to match jobsite needs.
Design features, such as the company’s axial piston, variable displacement hydraulic pumps and motors, provide load-sensing and load independent flow division (LUDV) hydraulics for smooth simultaneous operation. With the LUDV design, oil flow is distributed to cylinders independent of the load. The main advantage of this system is that the compact excavator can be performing multiple actions at one time, without sacrificing flow.
The auxiliary hydraulic circuit with open (pressureless) return provides for flexibility in adding attachments.
A quick-coupler bucket adaptor is standard for easy bucket and attachment changes. Ground level access to the engine, drivetrain and hydraulics ensures quick and easy maintenance. The machine’s engine hood tilts from the rear and features an expanded hinge height so you can easily perform your daily service checks safely and easily. The cabs on these machines are quiet due to the low engine noise, and ergonomically designed seats, visibility and ergonomically designed pilot controls ensure that the operator can comfortably sit back and operate the machine.
The pilot-operated controls also provide changeable control patterns to adjust to the operator’s particular preference.
Heat is standard on all models, and A/C is optional on larger units. Each unit is built with a large operator’s platform with two-sided entry for easy access from both sides of the machine.
Other standard features include: inverted, top-mounted boom cylinders for cylinder damage protection; reduced dirt buildup and protection from the elements; end-positioned, cushioned cylinders to extend service life while minimizing inertia forces and reducing cylinder shock; and the linkage on the Terex machines is more flush with the tracks, better protecting these vital parts, leading to more uptime and an increase in productivity.
Advice to Buyers
“No matter what attachment an operator wants to use with a compact excavator, the key to productivity is to make sure the machine’s hydraulic flow is matched to the attachment, and that it is easy for operators to change out and operate the attachment. For instance, quick-coupler systems make it fast and easy to change attachments, auxiliary hydraulics offer flexibility in adding attachments and load sensing hydraulics provide excellent multi-tasking capabilities for the boom, dipper and attachment,” says Gregg Warfel, district sales manager of compacts for Terex Construction Americas.
