Tracked Zero Tail Excavator EZ50: The compact and powerful zero-tail excavator

Full speed ahead: The EZ50 mini-excavator offers excellent lifting and digging power as well as quick work cycles. Using the newest technologies, the emissions of the mini-excavator were reduced and, at the same time, the efficiency increased. For example, the powerful engine in the EZ50 meets the stage 5 exhaust emission standards. In terms of operator-friendliness, the excavator is impressive. The intuitive operating concept and excellent view of the work area contribute to the easy and comfortable operation of the machine. The EZ50 is also a zero-tail excavator and is well suited for working in narrow spaces.

Flexible cylinder rod protection

The cylinders and the cylinder rods are protected from damage thanks to the plastic rails, which lengthens their service life and saves costs. Due to their flexible material, they return to their original shape after an impact. Their appearance and characteristics are completely retained.

3-point kinematics

With 3-point kinematics, the conventional bucket linkage has been taken to a new level. This "3-bolt" design extends the bucket's angle of rotation to 200 degrees - 10% more than conventional bucket linkage. This increases the vertical dig depth as well as the digging forces. This eliminates the need to reposition the excavator as often, significantly increasing efficiency.

Active Working Signal (AWS)

The red LED strip running diagonally over the engine hood lights up when the joystick control is pressed down. This signals to bystanders nearby that the excavator is ready for operation and can be moved at any time.

Load Sensing Flow Sharing

Load Sensing Flow Sharing enables precise and efficient control of the excavator. The machine adjusts to the load and the joystick movements are always kept the same for the operator.
The hydraulics work more efficiently, saving energy and ultimately costs. But it also makes operation easier for the operator.
Load-sensing systems help to regulate the flow rate according to demand. The less power is used, the lower the fuel consumption.

Zero Tail

When space is limited: Pivot safely, even in the tightest of spaces or right next to the wall - with the Zerotail excavator without rear overhang, no problem.
Optimal working in limited working conditions, high maneuverability and time savings are guaranteed.

Compact dimensions

High level of safety during transportation, cost and time savings. The excavator scores points with a low entry height and reduced external dimensions due to the intelligent component arrangement, providing higher stability thanks to the low center of gravity.
Whether during transportation or in tight spaces: thanks to its compact design, the excavator can easily be taken to your next job site. And on the construction site, the machine can maneuver anywhere easily and quickly, even in confined spaces - for high efficiency in every application.

Numerous attachments

Thanks to the optional additional control circuits, our excavators can be equipped with a variety of attachments. This way, you can increase your application options in no time and thus increase the utilization of your excavator.

Hydraulic thumb

The optional hydraulic thumb offers, beside a conventional bucket application, a grip function, which expands the spectrum of applications.
With this additional grip function, material can be cleared away quite easily.

Up to 5 additional control circuits ex work

Thanks to the optional additional control circuits, our excavators can be equipped with a variety of attachments. This allows for more application possibilities and increased utilization of the excavator.

Hose guidance by swiveling bracket

Optimum hose routing through the swiveling bracket provides the best possible protection for the hoses against external influences, which extends their service life. The field of vision is not restricted and abrasion of the hoses is significantly reduced.

Very good all-round visibility

The design of the machine has been specially adapted to the needs of the operator in terms of optimum visibility. For example, the right front track is very visible in the normal sitting position, which significantly increases safety for the operator and the surrounding area.
Everything in view - ideal view of the attachment and of the right front track as well as the side and partial rear section of the machine
