The PK 21.501 SLD 3 is a practical, efficient loader crane engineered for reliable daily operation. High Speed Extension accelerates telescoping for shorter load cycles. Single Link Plus tilts the knuckle boom up to 15° beyond horizontal, adding flexibility for the extended reach. 20.9 mt of lifting moment, 14.9 m of hydraulic outreach (19.1 m manual) and 330 bar operating pressure deliver strong performance — the proven SLD build and PALTRONIC control keep operating costs in check.
Practical for daily use
The PK 21.501 SLD 3 is engineered for reliable daily operation without extra complications. A strong 20.9 mt lifting moment and the proven SLD build make it a cost-effective choice.
Extended reach with Single Link Plus
Single Link Plus tilts the knuckle boom up to 15° beyond horizontal, adding flexibility on top of the 14.9 m hydraulic reach. Manual extensions grow the reach up to 19.1 m.
Smartly supported work
PALTRONIC monitors load and stability in real time. Paired with optional HPSC, lifting capacity is safely utilised for each setup.
