TRANSMISSION BOX


The Carraro - TLB2 model
POWERSHIFT type, automatic, low-speed, with 4 forward and 4 reverse speeds, automatic braking.
The enhanced low-speed Powershift automatic transmission with 4 forward and 4 reverse speeds provides high traction under all operating conditions.
The electrically operated speed switch provides the desired speed and power.
The coefficient 3.01/1 of the torque converter increases the maneuverability of the machine.
Electric drive choice for 2 or 4 wheels.
The machine has an ECU, an electronic control system for forward/backward movement and speed selection, which protects the gearbox from possible damage if the speed is turned on incorrectly.
DIFFERENTIALS


Reinforced and high-strength differentials have been selected for the new MST 6 Series.
The rear axle with a high-friction differential (LSD) prevents sliding in soft ground conditions, transferring different differentials to the left and right wheels even in the most severe conditions.
Thanks to the front axle, which has a 16° deflection angle, the new MST 6 Series operates efficiently even under the most adverse terrain conditions.
SPEED OF MOVEMENT ON ROADS

With standard tires and an engine speed of 2200 rpm.
Engine speed km/h
1 6.14
2 10.11
3 22.18
4 41.93
Brake system


The advanced braking system ensures efficient and safe braking of the machine in all conditions by means of oil-cooled disc brakes.
The presence of a battery in the braking system allows you to stop the car by lightly pressing on the pedal, even in emergency situations such as engine shutdown.
Smooth braking provides convenience for the operator during loading operations.
The precise turning radius and ergonomic dual pedal braking system for handling slippery surfaces ensure ease of use for operators.
Hydraulic system


The model is a helical double pump
Maximum pump pressure 250 bar
Maximum pump flow 155 l/min (at 2200 rpm)
The hydraulic system is equipped with special shockproof and anti-cavitation valves.
The discharge valve automatically adjusts the main and auxiliary pumps according to the required supply.
The hydraulic system has a cooler that can cool the hydraulic oil even in hot climates.
The oil filter of the hydraulic tank, connected to the drain line, captures particles up to 10 microns in size that may be in the oil.
The control levers for excavating and loading equipment are positioned to ensure ease of use for the operator.
The hydraulic supports of the backhoe loader are controlled by levers.
There is also a safety system that disables the hydraulic joystick during work.
Electrical system


The engine is equipped with 12 V DC, a 75A generator, a 135 Ah battery with heavy duty and low operating consumption, as well as a preheating system for starting the engine in cold weather.
