V-belt set for Demag AC 300

This V-belt set, identified by part number 78019873, comprises two individual belts designed to transfer rotational energy from a drive shaft to various driven components. These belts are used to operate auxiliary systems such as the alternator, water pump, cooling fan, or hydraulic pump within the machinery. The trapezoidal shape of the belts ensures a secure fit within the pulley grooves, which maintains the necessary friction for effective power transmission.

This set is specifically configured for the Demag AC 300 all-terrain crane. The belts are engineered to meet the operational requirements of the engine's auxiliary drive system, ensuring that power is consistently delivered to critical components during equipment operation.

V-belts function by utilizing the wedging action between the belt sides and the pulley grooves to transmit torque. As the engine shaft rotates, the belts drive the connected accessories, allowing the machine to maintain proper cooling, electrical charging, and hydraulic pressure levels. Regular inspection of belt tension and condition is necessary to prevent slippage and ensure the continued operation of the driven accessories.
