Manufactured using high-quality alloy steel (such as 42CrMo) by a die-forging process, rather than simply casting or welding The key connection hole (the part connected to the cylinder earrings, S valve swing arm) uses high precision CNC machining, tolerance control is extremely strict Surface hardening, wear-resistant, pin shaft hole parts are usually treated with high-frequency quenching or hard chrome plating Designed for pump trucks with Putzmeister DN80 or DN90 pipe diameters (e.g. common arm pump trucks from 32 m to 56 m)
