The Cat 735 with a 20 m³ (26.2 yd³)/32 tonnes (35.3 tons) capacity, offers demonstrated reliability and durability, high performance and productivity and a new world-class cab to improve operator comfort and ease of operation. Updating the successful 735C to include the new cab design makes the 735 a more attractive proposition for our customers. Class leading levels of performance and new features such as Advanced Automatic Traction Control (AATC) and Assisted Hoisting Control create operator comfort, making a productive machine all day long while retaining all axle enclosed wet brakes and Advanced Productivity Electronic Control Strategy (APECS).
