Patent number: 11541748Abstract: A tank system for a construction machine includes a fuel tank having an outer tank wall that closes off a tank volume to the outside, a withdrawal tank volume, which is separated by a partition wall from a main tank volume of the tank volume and has a fuel-exchanging connection to the main tank volume, and a fuel withdrawal arrangement having a main fuel pump and a withdrawal line opening into the withdrawal tank volume for conveying fuel by the main fuel pump via the withdrawal line from the withdrawal tank volume to a fuel-consuming system region. The tank system also includes a fuel feed arrangement having an auxiliary fuel pump for conveying fuel from the main tank volume into the withdrawal tank volume.Type: GrantFiled: November 25, 2020Date of Patent: January 3, 2023Assignee: Hamm AGInventors: Gerd Köstler, Stefan Reber, Armin Landstorfer

Patent number: 11427269Abstract: An articulated/swivel joint for the articulated connection between a rear section and a front section of a construction machine includes a joint mechanism assigned to a swivel-stop arrangement for limiting the swivel movement of a front joint part in relation to a rear joint part. The swivel-stop arrangement includes a first swivel stop for predetermining a maximum amount of swivel deflection during deflection of the front joint part in relation to the rear joint part in a first swivel-movement direction and a second swivel stop for predetermining a second maximum amount of swivel deflection during deflection of the front joint part in relation to the rear joint part in a second swivel-movement direction. When an articulated movement is performed, the maximum swivel-deflection range decreases as the amount of articulated deflection increases, starting from a neutral position of articulation of the front joint part in relation to the rear joint part.Type: GrantFiled: June 24, 2019Date of Patent: August 30, 2022Assignee: Hamm AGInventors: Gerd Köstler, Stefan Reber
