Construction machinery AHLMANN
Choosing an excavator or loader means deciding to work differently. This is a decision to introduce innovative technologies for job efficiency. This is a guarantee of greater comfort, safety for operators, residents, higher productivity of the construction site. Ultimately, it is more beneficial for the sustainability of our customers' businesses. Regardless of whether on wheels or on tracks, excavators are extremely compact and uniquely versatile for efficient site management. Digging, loading, processing, equipping with hydraulic tools is 100% everyday work life. As for wheel (front-end) loaders, it offers a wide range of solutions necessary for the effective organization of the on-site work process. Articulated, with four steered wheels, equipped with a swivel bracket, telescopic - there are so many options, among which our customers will certainly find a loader that meets their expectations.
EXCAVATORS
AHLMANN excavator capacity: 6 to 15 tons, according to your requirements. Wheel excavator loaders: the perfect combination of excavator and loader, extremely mobile throughout the terrain thanks to the articulated chassis, 4-wheel drive and 360 ° rotation. Crawler backhoe loaders are an intelligent, innovative merger of a mini excavator reaching 10 km / h and a full swing loader. The range of excavators is also designed to reduce the number of machines at work sites and to participate in protecting our environment. Wheel excavators meet the required tasks when lifting, digging depth, processing, while maintaining the mobility of the undercarriage on wheels. Crawler excavators, ideal for those looking for Ultime stability and want to take advantage of compactness and versatility.
