Tracked excavators are stable and powerful enough for almost any project. Rental agencies especially like small models that can be profitable pieces of equipment. With the market in place, Wisconsin-based Wacker has launched five new compact tracked excavators.
For the smallest spaces, the 1404 turns a day of digging by hand into minutes. It is equipped with a Yanmar three-cylinder diesel producing 24.3 hp (18 kW). With a mass of 1.4 ton (1.3 t), the little machine can dig up to 88 in (2235 mm) down while remaining light enough for most surfaces. The excavator is also compliant with ROPS (roll over protective structure), TOPS (tip over protective structure), and FOPS (falling object protective structure) regulations. There are two models with either short or long dippersticks.
For slightly larger projects, the 3503 is available. This model comes with a 48-hp (36-kW) four-cylinder diesel, also by Yanmar. The digging depth is 129 in (3277 mm), but a mass of 3.5 ton (3.2 t) means that it is not as geared toward small projects as the 1404. The 3503 also comes with short or long dippersticks and claims to be the most powerful unit in its class.
If the 3503 is not as maneuverable as needed, the 38Z3 is very similar in size and weight but features zero tail swing. The Yanmar engine is a 37-hp (28-kW), three-cylinder model, powering the hydraulic arm to a depth of 122 in (3099 mm). The cab-equipped models come standard with A/C and tilt for easy servicing.
For bigger digs, although probably not Boston-sized, the 50Z3 is a more refined machine with separated cab and engine spaces, zero tail swing, and the biggest cab in class, standard with A/C. Yanmar power comes in the form of a four-cylinder 48-hp (36-kW) diesel, allowing a longer arm that can reach up to 138 in (3505 mm).
The largest model in the Wacker excavator line is the 8003. Tipping the scales at 8 ton (7.3 t), it needs all 70 hp (52 kW) from its Yanmar four-cylinder diesel. The dipperstick can reach up to 169 in (4293 mm), unhampered by the short tail swing.
All models come with rubber tracks, dozer blades, work lights, and a control pattern selection system.
