REACHSTACKERS 42 – 45 TONNES
TECHNICAL INFORMATION CONTAINER HANDLER, DRF
Flexible Container Handling
Reachstackers from Kalmar combine performance, comfort and reliability.
Container handling with a reachstacker is one of the most flexible handling solutions whether to operate a smaller oneunit terminal or a medium sized port. A reachstacker can handle loaded containers quickly and efficiently in narrow spaces, while still ensuring the driver has optimum visibility.
The extensive freedom allowed by the lifting equipment, boom and attachment, and its rotation possibilities, gives that the driver can improve the work efficiency of the unit, by not needing to approach the container from a 90 degrees position.

unloading. |
Instead, the container can be picked or dropped-off by the unit approaching from any angle <90 degree. And by rotating the spreader and reaching the boom to suitable length, the driver can handle the container from any position. As an additional advantage, the aisle width - driving space depth, needed - can be squeezed, as well.
Wear on the machine and the working surface can be reduced if the reachstacker is used in the right way. Compared to a conventional forklift, a larger proportion of the lifting manoeuvre can be performed while the unit is stationary.
Containers can also be lifted and transported lengthwise, making it possible to deliver the container into and through workshop doors, port shed gates, etc in then low, longitudinal position. This can be a vital ability for the possibility of container stripping and stuffing inside the sheds.
The goals in developing a reachstacker are clear: high performance throughout the operating cycle, high user-friendliness, and low running costs. Together with a high level of environmental awareness, this has resulted in new technical solutions and systems.
Any driver with the ability to take advantage of the machine’s capacity and technical benefits will find this reachstacker a powerful, flexible tool for handling containers with the lowest possible operating and maintenance costs.
The technical information in this material primarily refers to the DRF. Specific information about the DRD’s technical systems is available on request.

Capacity and dimensions
Maximum lifting capacity in confined spaces.
The chassis and lifting equipment have been developed to ensure the best possible performance, strength and user-friendli- ness. The nature of the working environment and capacity requirements at different load centres determine which model is the most suitable.
Lifting boom
The lifting boom carries the load. The design has been optimised using computer simulations and extensive field tests. The powerful execution in high-tensile steel has a minimal number of welds for maximum strength. The boom’s fixture in the frame and the lifting cylinders are fitted
with spherical plane thrust bearings. The width of the rear fixture (boom suspension) increases the overall rigidity and the good rearward visibility.
The boom has two sections, the inner and outer boom. The sliding plates between the inner and outer boom require no lubrication. The cable-chain which leads hydraulic hoses and cabling to the attachment is made of maintenance-free plastic.
Lifting boom hydraulics
Oil is fed to the boom functions by load sensing pumps. To reduce pressure drops, wide hydraulic hoses have been used for the boom functions. A wider hose produces a lower flow rate with the same volume, thereby reducing friction and heat development.

The blocking valves on the lifting and extension cylinders block the oil flow when the boom functions are not in use, which secures the boom position. The base of the lifting cylinders has a new design that produces smooth stopping and starting movements.
The boom’s lifting and extension function is damped in the end positions for reduced wear and greater comfort.
Rotator
The rotator is fixed in the inner boom and enables the container to be rotated. The rotator consists of an upper and a lower yoke joined with a powerful bearing. Rotation
is enabled by two hydraulic motors, which drive a gear-ring. Two hydraulic dampers help prevent the container from swinging lengthwise.

Attachment
The primary function of the attachment is to firmly attach the container during lifting. This is done with four twistlocks which rotate, thereby securely gripping the container’s corner fittings.
The mechanical levelling ensures that the twistlocks reach the corners, even if the container is leaning.
The attachment can easily be adapted to different container standards. A hydraulic motor drives the function via chains. The container can also be moved sideways to facilitate loading and unloading, or to compensate for unbalanced loads. Two hydraulic cylinders perform the side-shift movement.
Attachment and rotator hydraulics
The functions are fed with a constant pressure, which means there is no pumping of hydraulic oil when the functions are not in use. One valve serves all the hydraulic functions in the attachment. The valve ensures that each hydraulic function is fed the exact amount of oil needed to optimise the speed of the functions’ movements. The attachment functions are damped in the end positions.
Chassis
The frame forms the basis of the machine’s lifting and manoeuvring characteristics. The frame’s beam construction, along with its width, makes the reachstacker stable, torsion resistant and service-friendly.
Firstly, a large number of computer simulations have been run in order to eliminate critical tensions under various kinds of strain. The simulations were characterised by uncompromising demands on the fundamental principles of stability, manoeuvrability and visibility. Secondly, the machine has then undergone extensive field-testing to fully ensure its dynamic strength.
The reachstacker is available with a variety of wheelbases to fulfil demands on lifting capacity in relation to manoeuvrability and operating economy in the best way.
Increased capacity
In some cases, high capacity requirements in the second and third rows of containers, or on the far rail track, call for the benefit of support legs. In other cases, it may be the restricted handling space that determines the most suitable model.
