Kalmar DRF 400-450 is a “Reachstacker” for container handling. The
machine has a lift capacity of 40–45 tons depending on version.
The engine is a six cylinder four-stroke direct-injected diesel engine.
The transmission is hydromechanical with gears in constant mesh.
It has four forward gears and four reverse gears. The engine power
is transmitted with a torque converter.
The driveline/axle consists of a propeller shaft and a rigid drive axle
with hub reduction. Drive takes place on the front wheels.
The service brake is of the type disc brake in oil which is built togeth-
er with the drive wheels' wheel hubs. The parking brake is of the

Load handling is components and functions for handling loads.
Loads are lifted with an attachment that is mounted on a liftable tel-
escopic boom. Load handling is divided into the functions lift and
lower, extension, sideshift, spreading, rotation, tilt, levelling and
load carrying. Lift and lower is the function to lift and lower the
boom. Extension is the function to push out and retract the boom.
Sideshift is to move the attachment sideways in relation to the ma-
chine. Spreading is to adjust the width between the attachment's
lifting points. Rotation is to rotate the load in relation to the machine.
Tilt is to angle the load in the machine's longitudinal direction. Lev-
elling is to angle the load in the machine's lateral direction (side-
ways). Load carrying is to grab the load.
The control system are functions for warning the operator of danger-
ous situations and malfunctions. The control system has diagnostic
possibilities that facilitate troubleshooting.
The frame supports the machine. The engine, transmission, drive
axle and steering axle are mounted in the frame. On the frame's
sides there are tanks for fuel, hydraulic oil and oil for the brake sys-
tem. The cab is located in the centre and can be moved fore-aft. As
an option the cab is available in a side-mounted version that can be
raised and lowered.
