Key Specs
Cat® 770 is built to move materials efficiently in construction and quarry applications, helping operators improve productivity and hauling performance. Paired with Cat 986, 987, or 988 Wheel Loaders and Cat 374 Hydraulic Excavators, the 770 delivers safe, dependable material movement across a wide range of hauling environments.
Easy service access helps customers spend less time on maintenance and keep equipment working longer.
Faster cycle times and improved machine performance translate into more material moved per shift.
Customers benefit from efficient performance that helps reduce fuel consumption and lower operating costs.
