Bucket wheel excavators (BWE)
The Joint Stock Company UNEX has been manufacturing bucket wheel excavators for more than 50 years. So you can consider UNEX to be an experienced specialist in manufacturing of large-scale machinery for use in open pit-mines. The UNEX team of well-trained specialists is able and ready to react to all its customers’ individual requirements. More than 130 custom-built excavators and reclaimers can be found in e.g. Czech Republic, Russia and the Ukraine, in Bosnia and Herzegovina, Macedonia, Bulgaria, Poland and Slovakia.
There are two types of bucket wheel excavator: Compact and Classical. The division depends on the possibility of repeated assembly and disassembly.
1. It is not possible to assemble and disassemble the Classical BWE. The excavator moves on either a caterpillar or walking undercarriage. Their capacity ranges from 1 200 to 6 500 m3/h and the specific cutting force from 90 to 168 kN/m. According to the adjustable distance between the wheel and the axis of the machine, classical BWEs are divided into two groups: excavators with a telescopic bucket wheel boom (KU 300 and KU 800) and without a telescopic bucket wheel boom (K 2000).
2. The Compact BWE can be repeatedly assembled and disassembled. Their capacity ranges from 400 to 2 800 m3/h and the specific cutting force from 25 to 145 kN/m.

The DH 40.1 excavator is the largest model in the range of a new generation of hydraulic excavators. Its high-class design, comfortable cabin, easy attendance and maintenance, high performance, optimal energy utilization in the ESU hydraulic system and low fuel consumption are typical features of this range. The excavator is equipped with reliable PERKINS engines and a high-quality REXROTH hydraulic system and thus it meets the highest requirements as regards performance and reliability. Undercutting, loading and many other different types of devices can be connected to an excavator.
The new undercarriage design enables easy manoeuvrability and offers the ability to work and maintain stability on all types of rough ground. Stability can be increased by adjusting the track width. By selecting the bearing of caterpillar supporters it is possible to convert the undercarriage either to a standard model (excavator with an undercutting device) or to a heavy model (suitable for machines equipped with a loading device).

Owing to its firm construction and the use of top-quality imported elements, the DH 921 is comparable with its most advanced competitors from all over the world.
The wide range of booms, connecting devices and working buckets enables these excavators to be universally use in extremely hard conditions.
DH 921 – the type with a loading device, is intended for work in stone pits. The safety of operating personnel is ensured by a FOPS protection frame, which protects the cabin from falling objects and also has a front safety grille. The design of the attendant’s workplace provides a comfortable atmosphere for the attendant and offers easy and sensitive control. The two-circuit hydraulic system is controlled in accordance with the load and deviation of the activators.
Special traction power and undercarriage road clearance provide good manoeuvrability and the ability to work on almost all types of rough ground.

The DH 28.1 excavator represents a new generation of UNEX machinery. It is an outstanding machine with a top-class design, comfortable cabin and very easy attendance and maintenance. Its advantages include high performance, the ability to work on almost all types of rough ground, optimal energy utilization in the ESU hydraulic system, and low fuel consumption.
The ESU system (UNEX economical system) is a two-circuit system that has all the functional advantages of a three-circuit system with no increase in acquisition costs. It draws only as much energy as is needed from the power unit at a given moment.
The new design of the cabin and revolving upper part and also the installation of the Perkins 1006-6TW engine has helped to reduce the internal and external noise levels. It is possible to connect a wide variety of devices to the deep digging boom, allowing different kinds of work to be done throughout the whole active radius of the machine. The excavator can be equipped with a loading device.

A strong articulated loader with a digging arm - in simple terms, these are the characteristics of the FIORI Articulated Backhoe loader. The only backhoe loader in the world that is articulated. The only backhoe loader in the world that has a loading arm with Z kinematic mechanism (typical of the loader). The only backhoe loader in its category to achieve 2704 mm in loading height and 3000 mm in excavation depth. In other words, a shovel equipped with forks and a back-end excavator in one single machine at top performance levels.

With 23 models in operation worldwide, ranging from 470 kg to 5,400 kg, Hitachi mini excavators provide the right type of service whatever your construction needs. The increasingly-popular zero tail swing type has a reduced cabin back that doesn't hang over the crawler. This prevents damage from contact with job site obstacles, which in turn reduces operator stress from worrying about accidents. This is why so many of Hitachi's zero tail swing mini excavators are used for narrow job sites. In order to function in such narrow spaces, excavators also have to be safe. Hitachi mini excavators come equipped with various safety features, such as TOPS (tip-over protective structure) and FOPS (falling object protective structure). To avoid the dangers of urban construction, our machines meet ISO safety standards.
