When purchasing a single hoist, you need to choose the type and direction of the pump output shaft based on the output interface type of the take-up clutch on the chassis. There are three types of output interfaces on the domestic take-up clutch: six-toothed keyway, eight-toothed keyway (DIN5462), and flange. The six-toothed keyway is generally matched with a gear pump, and a transmission shaft and transition plate are required for flange installation. It is recommended to use an eight-toothed keyway (DIN5462) output shaft and directly insert the pump into the installation. When specifying the DIN5462 output interface take-up clutch on the chassis, you can use the eight-toothed keyway output shaft pump for direct installation, simplifying the installation.
