HKZS

Heavy-duty hydraulic load-bearing boom — tractor-mounted

The HEMOS HKZS has been developed for heavy-duty work where power, reach and reliability matter. The robust construction and reinforced boom make the machine suitable for intensive use. Thanks to its own pump unit, the HKZS has fully sufficient hydraulic capacity for both the boom and the attachments. The three-section boom combines a large working reach with a compact transport position. The HKZS itself is neither a mulcher nor a mower — mulcher, bucket, rake and milling heads are interchangeable attachments on it. It differs from the ORCA in its class (heavy work: ditches, embankments, heavy milling), and from the Hemostrac in that it works on the customer's tractor rather than being a self-propelled machine.

Engineering

HKZS: how it is built

The HEMOS HKZS is designed for heavy and intensive work. The machine combines a robust structure with its own efficient hydraulic system and a three-section boom, providing a large working reach and a compact transport position. Thanks to the option of fitting various attachments, HKZS suits a wide range of applications.

01
Design principle

Chassis, slewing head and support wheel

The sturdy chassis is easy to mount on the tractor, and the robust slewing head works with a slew cylinder. The support wheel folds hydraulically, giving optimal stability in work and not getting in the way in transport.

02
Hydraulics

Pumps and valves

The pump unit is equipped with 2 Load Sensing pumps, optionally expandable with a third pump, each with a maximum capacity of 150 l/min. They supply, among other things, the hydraulic cylinders, the slew cylinder and the attachment drives. In addition, 1 gear pump is fitted, optionally expandable with a second, for functions such as the oil cooler and smaller attachment functions, for example the discharge belt of a flail mower. As a result, sufficient hydraulic capacity remains available even when several functions are operated at the same time.

03
Control

Own hydraulic system and CAN-Bus

HKZS is equipped with its own hydraulic system and CAN-Bus control. The pump unit, driven from the PTO, provides the required hydraulic capacity for the boom and attachments. All functions are operated from the cab using the Danfoss joystick and IQAN touchscreen. Machine data and faults are shown on the screen, and various settings can be easily adjusted.

Three-section boom 2.5 + 0.9 + 1.95 m
Konstrukcja · 01

Three-section boom

The HKZS is fitted with a three-section boom, which allows a compact transport position with most attachments. The robust construction makes the boom suitable for heavy-duty work. The machine's boom length fully extended is 5.35 m, measured from the first to the last pin. Boom section lengths 1–3: 2.5 m | 0.9 m | 1.95 m.

HKZS folded for transport
Konstrukcja · 02

Transport position

The compact transport position allows safe travel between work sites. Transport height remains below 4 metres when matched to the tractor and attachment.

Danfoss joystick in the cab
Konstrukcja · 03

CAN-Bus control

Control is via a CAN-Bus, using an electric Danfoss joystick and HEMOS software integrated with the IQAN display. The joystick provides precise control of the boom and attachment functions. This means the machine can be operated with one hand, while the other remains free to steer the tractor.

IQAN display working screen
Konstrukcja · 04

IQAN display

The IQAN touch display shows oil temperature, working pressure, travel speed, engine hours and metre counter. In addition, various functions can be operated, including the support wheel, hydraulic function settings can be easily adjusted, and any faults are displayed.

Pump unit, hydraulics
Konstrukcja · 05

Pump unit

The pump unit running at 1,000 rpm provides the hydraulic capacity required for the functions of the HKZS and its attachments. The unit has its own 200-litre oil tank, a hydraulic oil cooler with automatic reversing cycle, a gearbox, and several high-pressure and gear pumps.

Oil cooler with reversing fan
Konstrukcja · 06

Cooler with reversing fan

The cooling system prevents dust, grass and dirt from accumulating in the cooler. The hydraulic oil cooler is fitted with a hydraulically driven reversing fan, which automatically changes its direction of rotation. This automatic reversing cycle regularly blows out the cooler and maintains cooling performance.

Hydraulic stabilising cylinder
Konstrukcja · 07

Hydraulic stabilising cylinder

For maximum stability, the pump unit is fitted with a hydraulic stabilising cylinder, chain-linked to the lower links. This keeps the machine securely fixed in the tractor's linkage and prevents it from tipping over via the support wheel. This connection provides high stability during operation.

Conversation with an engineer.

The most common questions we hear from farms before purchase.

We have collected the questions we most often hear from farms before purchase — and the answers from our engineers. Every answer is based on verified knowledge of the machine.

  • manufacturer's materials
  • dokumentacji technicznej
  • questions asked by farms

Answers based on the experience of thousands of farms in Europe.

An engineer answers

A heavy-duty hydraulic loader boom mounted on the tractor, with its own pump unit driven from the PTO. It is not a mulcher or a mower: mulcher, bucket, rake and milling heads are interchangeable attachments on its boom.

An engineer answers

The boom has three sections: 2.50 + 0.90 + 1.95 m. Its extended length is 5.35 m, measured from the first to the last pin.

An engineer answers

Yes. The three-section boom gives a compact transport position, and the transport height stays below 4 metres when the boom and attachments are matched to the tractor.

An engineer answers

CAN-Bus control: electric Danfoss joystick and IQAN touchscreen display with HEMOS software. The machine is operated with one hand, leaving the other free to steer the tractor. The display shows oil temperature, working pressure, travel speed, engine hours and metre counter.

An engineer answers

From its own pump unit driven from the 1,000 rpm PTO: 200 l tank, AM 230 gearbox, 2 Load Sensing pumps at max. 150 l/min each (optional third pump) and a gear pump (optional second). Hydraulic control is handled by a 10-section, electro-proportional Parker L90 valve block.

An engineer answers

From ORCA, by class: HKZS is a heavy machine for ditches, embankments and heavy milling. From Hemostrac, by way of working: HKZS is mounted on the customer's tractor, whereas Hemostrac is a self-propelled machine with its own cab and registration.

An engineer answers

The Hemos catalogue gives neither the weight nor the required tractor power. We do not guess: we confirm both figures with the manufacturer for your configuration. Give us the tractor make and model, and we will prepare a mounting specification and an offer.
