Uniquely-designed lift arm on articulated loaders


Gehl Company

Gehl’s new compact articulated loader models – 140, 340 and 540 – feature tipping loads ranging from 1,900 to more than 5,100 pounds (when not articulated) and rated operating capacities from 950 to more than 2,550 pounds. Engines range from 23 hp on the 140 model to 47 hp on the 540. They can use most universal-type attachments, putting tools customers already own to good use.

A heavy-duty oscillating joint offers 45-degree turning angles to the left and right and 10 degrees of oscillation in both directions. The bucket and tires follow a constant turn radius, so the rear tires of the loader follow the path of the front tires. Narrow machine widths, as narrow as 41 inches on the model 140, allow access to tight, confined spaces that most skid-steer loaders with comparable operating capacities cannot access.

Lift arm and bucket float features allow for “floating” of the lift arm and bucket for light scraping and rearward leveling actions.
The uniquely-designed lift arm on the Gehl articulated loaders is designed to achieve maximum strength, excellent visibility and fast cycle times. The parallel-type linkage on the models 140 and 340, and “Z” bar-type linkage on the model 540 provide excellent bucket breakout forces from 2,433 lbf. on the model 140 to 10,749 lbf. on the model 540. The unique linkage design allows for mechanical self-leveling action in both the up and down directions, excellent bucket dump angles at the mid- and top-ranges of the lift path, as well as outstanding forward reach.
