HGPT, HGPL and HGDT are three types of parallel gripper and three point gripper. They are robust, safe and flexible. HGPT can grip parallel, HGPL is ideal for long strokes and HGDT has a high load capacity. These three grippers have a convincing concept, which saves space and can be combined with other Festo components (such as slides, handling axes and rotary drives). Selection and design can be made easily with a software tool from the digital catalogue. HGPT and HGDT have a high force and torque load capacity thanks to the embedded and paired T-slots. They also have blocking air to prevent cutting fluid and dust from entering. These three grippers have a high degree of design freedom thanks to the mounting options on different sides. Increased flexibility is provided by a grip force safety device, such as in multiple grip plates: two or more grippers can be installed more quickly when used simply. HGPT and HGDT are ideal for dynamic applications because they have a grip force safety device that can securely hold the workpiece when the pressure drops. If the gripping process requires more grip force, the spring force will support the grip force, so it is not necessary to select a larger gripper.
This leaflet presents the Festo parallel grippers HGPT and HGPL as well as the triple‑point gripper HGDT. It describes their design concepts, integration options with Festo handling modules, and the benefits for construction and procurement, such as high gripping forces, robust construction, and integrated sensor interfaces.
Technical data, calculation aids for gripping force, recommended safety factors, and guidelines for proper pneumatic supply are included. The document also outlines possible applications, selection criteria, and safety notes for using Festo elements in industrial environments. This manual is written in German.
