The Link-Belt 750 X4 excavator is a heavy-duty hydraulic excavator designed for demanding earthmoving applications. It operates at a weight of 158,300 lbs (71.8 metric tons) powered by a robust 512 horsepower (382 kW) Isuzu AQ-6WG1X engine. The machine features a maximum digging depth of 27.58 ft and a maximum reach along the ground of approximately 42.92 ft, providing significant versatility and reach on large job sites. Its advanced hydraulic system includes electronically controlled pumps and a proprietary control valve with enlarged ports to ensure superior hydraulic flow, resulting in faster cycle times and optimal machine responsiveness. The excavator offers strong breakout and bucket digging forces, rated at 68,790 lbf, enhanced further by Auto Power Boost to 75,090 lbf. Its boom down and swing circuits deliver operating pressures around 4,000 to 5,000 psi for powerful and precise movements. The swing mechanism uses a planetary reduction powered by an axial-piston motor with a free-swing feature and a swing speed of 6.7 rpm. Fuel capacity is large at 238 gallons (900 liters), supporting long operating cycles. Operator comfort and safety are enhanced with features like an OPG Level 1 certified cab with automatic climate control and a 7-inch HD color monitor with rearview camera integration. The 750 X4 combines durability and efficiency, with an 8% faster cycle time and improved fuel efficiency compared to predecessors. It is backed by a five-year, 5,000-hour full machine warranty and benefits from the Low Cost of Ownership Award in its class by EquipmentWatch. Designed to maximize productivity and reduce operational costs, it is suitable for heavy excavation, material handling, and challenging construction tasks.
