History and service record of 773, 775, and 775 Bare Chassis
- Testing before production. Caterpillar says the 773 was designed and manufactured with virtual and hands-on quality control technologies and logged more than 30,000 hours of customer operation before production, and that the 775 accumulated the same 30,000 hours of proven operation before it was built for customers. 773 off-highway truck, Boyd Cat (Caterpillar product text); 775 off-highway truck, Caterpillar.
- Fuel-saving features. Cat's 773 product text lists seven different ways the truck conserves fuel, including hauling at a more fuel-efficient engine speed and gear selection with speed limiting. 773 off-highway truck, Boyd Cat (Caterpillar product text).
- Fleet management on the 775. The 775 is described by Caterpillar as MineStar ready, with Cat Product Link Elite and VIMS included to help with equipment management, remote monitoring and machine availability. 775 off-highway truck, Caterpillar.
- Bare chassis for body builders. Caterpillar lists the 773 and 775 as bare chassis trucks as well as complete trucks, and its page for the 773 bare chassis sends buyers to Caterpillar OEM Solutions for the options. 773 bare chassis off-highway truck, Caterpillar.
- The next-generation 775 frame. Cat's 775 page describes a next-generation truck with a lower center of gravity, a double A-type front suspension for ride and faster cycles, a rolled-form body with about 10 percent more volume and an enhanced turning radius. 775 Off-Highway Truck, Caterpillar.
- Seat moved to the left. The newer 775 moves the operator's seat to the left side for easier operation, adds a newly designed cab with more storage and automotive-quality shifting controls, and includes automatic cab temperature control. 775 Off-Highway Truck, Caterpillar.
- Ready for autonomy. Cat says the 775 is engineered with autonomy in mind, with wheel speed sensors and a designated space for the GPS mast so Cat MineStar Command for hauling can be installed later. 775 Off-Highway Truck, Caterpillar.
- Gear speeds. The page lists seven forward speeds on 24.00R35 tires, from 10.7 km/h in first to 67 km/h in seventh, and 14 km/h in reverse, with a hill-hold function that stops the truck rolling the wrong way on a gear change. 775 Off-Highway Truck, Caterpillar.
- 775 payload and fuel modes. Cat's 775 page lists a 70.5 ton (64 t) nominal payload class, a loaded top speed of 66.9 km/h, seven fuel-saving features and two customizable fuel economy modes, with up to 13 percent less fuel consumption from Adaptive Economy Mode and APECS. 775 (07) Off-Highway Trucks, Caterpillar.
- 775 field hours and altitude. Cat says the 775 had accumulated more than 30,000 hours of customer operation when launched, and lists Tier 4 Final and EU Stage V compliance with no engine derating up to 3,048 m (10,000 ft). 775 (07) Off-Highway Trucks, Caterpillar.
- 773 engine and weight split. The 773 technical specifications list a 27 litre engine with 137 mm bore and 152 mm stroke and a 40 percent net torque rise, standard 24.00R35 (E4) tires and an empty weight split of 52 percent front and 48 percent rear that shifts to 34 and 66 percent loaded. 773 Off-Highway Truck Technical Specifications, Caterpillar.
