What does the C gear mean in a truck?

[McValentina]

C gear is the climbing gear, also known as the half gear. It is mainly used in heavy-duty trucks, and the relevant introduction is as follows: 1. C gear is the climbing gear: Also known as the half gear, when the truck is heavily loaded and the road conditions are poor, such as muddy or uphill, the half gear can reduce speed and increase torque, which means the forward traction is enhanced, improving the heavy-duty truck's passability in poor road conditions. The gear ratio of the half gear is the largest among all gears, hence it provides the strongest traction. 2. R gear is the reverse gear: When the gear lever is placed in this position, the hydraulic system's reverse gear circuit is engaged, causing the drive wheels to rotate in reverse, enabling the vehicle to move backward. To operate, the safety button on the gear lever usually needs to be pressed before moving the lever to the "R" gear. It is important to note that when the vehicle has not come to a complete stop, forcing the gear lever into the "R" position should be avoided, as it can damage the transmission.
