Wheel loader AR 640
129 kW (173 HP)
2,5 - 3,0 m³
A wheel loader as versatile as a Swiss army knife
Thanks to its bucket capacity of 2.5 to 3 m³, the weycor AR 640 wheel loader is perfectly suited for heavy-duty applications. Like a Swiss army knife, it takes on any task: From main construction to industry to working in the sand pit or agriculture. There are no limits for this workhorse.
With a service weight of 13.5 t and an engine output of 129 kW (173 HP) the new generation of the weycor AR 640 wheel loader combines pure power and performance with lower fuel consumption.

Features and benefits
Powerful drive unit
A weycor wheel loader of the XXL class can be moved in two ways: in operating speed range from 0 to 14 km/h or in optional high speed at up to 40 km/h. Here, 1st and 2nd hydraulic gear as well as forward / reverse travel can be engaged under load. The switching between the forward / backward travel, speed ranges and off-position is done via the weycor joystick. The drive is operated by accelerator and separate inching pedal for best distribution of the hydraulic power for thrust and lifting forces. Optional traction via 100 % electrically-operated differential lock in front and rear axles.
Only manufacturer with a separate inching pedal & the drive pedal function
Precise distribution of shearing and lifting forces, along with reduced wear and fuel consumption. Unlike a combined braking /inching pedal, the separate inching pedal eliminates the risk of inadvertently activating the main brake. The use of the accelerator as the drive pedal is just as practical. When using the hand throttle, the engine speed is kept constant, however the angle in the drive pump is variable. Here, again, the thrust force is finely regulated.
Wear-free negative brake
Holds the wheel loader securely in position on a slope when the brake or inching function is activated. All four wheels are automatically locked, even when the engine is stopped. The multiple-disc brake runs in an oil bath and is particularly low-maintenance and low-wearing as a result.
Articulated joint & floating axle
For outstanding off-road capability and manoeuvrability. Unique stability because of the low centre of gravity, even off-road.
Optional hydraulic quick-change mechanism according to ISO 23727
Makes it possible to change the attachment in seconds and turns the wheel loader into a real all-rounder.
The latest kinematics
Tried and tested weycor kinematics with high breakout forces and an excellent lifting height.
Safe, fatigue-free working with excellent all-round visibility, clearly arranged instruments and ergonomic design. Readied additional mounting points for optional accessories.
Fast, easy maintenance and upkeep as a result of centrally arranged, easily-accessible service points.
Unique engine mount
Independent suspension of the engine decoupled from the axle to avoid vibration and noise emission.
