2025 Caterpillar Open Bowl Scrapers 657
High productivity / low cost solutionCat® Wheel Tractor-Scraper 657 twin engine has the power to boost productivity by utilize push-pull loading. Combine this ability with improvements in productivity, enhancements in operator comfort, and new safety features – Powered Access System and effective wet disc brakes – and you have a machine offering high returns on profit and time.
Features may include:
BE MORE PRODUCTIVE- Advanced Productivity Electronic Control System (APECS) allows the engine and transmission to communicate on a high level. This communication allows the machine to better utilize the power and torque the engine is producing. The net result is moving more material.
- Use Ground Speed Control to set the desired top speed and the machine will find the gear that works best for the engine and the transmission, providing a lower fuel burn.
- The Machine Speed Limit feature replaces Top Gear Selection.
- Auto-Stall assists in quickly bringing the transmission to an operating temperature at start-up when the machine is working in a cold climate region.
- Cat® Payload Estimator for scrapers is an earthmoving solution for optimal payload and job site efficiency. Payload Estimator achieves on-the-go weighing by using bowl lift cylinder pressure during the loaded haul segment. Payload Estimator is optimized to be used with Sequence Assist, which provides increased productivity with less operator effort.
- Steer with less effort with the newly designed High-Pressure Steering system.
- Reduce up to 14 individual operator commands per cycle with
- Sequence Assist (optional attachment).
- Enjoy interior improvements and a more ergonomic work environment with a 21% larger cab than the 657 G-Series cabs.
- Intuitive, ergonomic controls with multifunction display keep operators focused on their work.
- Maintain desired cab temperature with Automatic Temperature Control.
- Temperature Control.
- Get in and out of the cab easier with the new powered access ladder system (optional attachment).
- Enhance an operator’s awareness of site surroundings with the
- Ground level access to fuel fill and daily maintenance points.
- Seat belt indicator provides visual and audible alerts when the seatbelt is not in use.
- Advanced Cushion Hitch allows the cushion hitch to prevent end stroke by having the ability to predict end stroke events and manage the rate of dampening, resulting in reduced hitch maintenance and improved operator ride in rough conditions.
