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).

Optimal Loader/Truck Pass Matching
| Hydraulic Excavators: 349/352 - Passes | 4-5 |
|---|---|
| Hydraulic Excavators: 336 - Passes | 5-6 |
| Wheel Loaders: 972/972 XE - Passes | 3-4 |
| Wheel Loaders: 966/966 XE - Passes | 4 |
| Wheel Loader: 962 - Passes | 4-5 |
| Wheel Loader: 950 - Passes | 5 |
| Note | An optimum system match gives you a major productivity advantage. The 735 is an excellent match for the Cat 349 and 336 Hydraulic Excavators; and Cat 972, 966, 962 and 950 Wheel Loaders. Having matched loading and hauling tools results in increased production and lower system costs per unit of volume moved. |
