With the SY50U, you can always see what you‘re working on, even in poor visibility. The powerful LED light‘s guarantee that the work area is optimally illuminated. Their energy usage is pleasingly low, ensuring that the battery has a long service life. Furthermore, the headlights require almost no maintenance, which saves time and repair costs.

Quick Details

With the SY50U short-tail-swing excavator, you have a specialist at your side that can prove its power especially in confined spaces. It requires little space, so can work and manoeuvre everywhere where conventional machines reach their limits – in places that are difficult to access, directly next to walls and house walls, on construction sites in busy inner-city areas or on busy roads. You can rely on its responsive, precise control and on the fact that this small machine is ranked at the level of significantly larger machines in its class in terms of speed and power.

The SY50U is equipped with a particularly effective load-sensing hydraulic system. The piston pumps with a variable flow rate ensure sufficient power to carry out all operations smoothly and safely. The well-balanced combination of speed, power and precise response behaviour guarantees high cost-effectiveness with fuel in every phase: The hydraulic pump always delivers just enough oil as is actually needed.
