Skidder EQUUS 240 UN
With its dimensions, wheelbase, weight and towing capacity, the EQUUS 240 UN belongs to the higher class of forestry special machinery with 6-cylinder engines. The advantage of this machine, however, is its lower fuel consumption and better trafficability, especially the large front and rear approach angle.

Transmission
The choice of the EQUUS hydrostatic-mechanical drive with one large-volume hydraulic motor with 45° degree technology results in the most economic operation during work. The hydrostatic transmission has high braking characteristics without the need to use service brake. The hydrostatic transmission is equipped with mechanical two-speed final drive by NAF with the capability to disconnect the 4×4/4×2 rear axle for driving on roads. Compared to 2-hydraulic motor version of our competitors, EQUUS hydrostatic transmission has demonstrably higher efficiency in speeds lower than 18 km per hour.
Working hydraulics
The Load Sensing hydraulic system is driven by axial piston pump DANFOSS 130 cm3/rev, with the output of 286 l/min at 2200 rpm. The maximum working pressure is 350 bar.
Control of the system is possible thanks to ETL intended to monitor the instantaneous power of the combustion engine. It places no load on the combustion engine and does not reduce its speed when it is under load.
Axles
Axles by the German producer NAF are the top choice for forestry machinery. Our choice was the heavy-duty range even for the basic model, and without any surcharge. The axles have 100% mechanical locking, independent for the front and rear axles. Both the service and parking brakes are located in an oil bath inside the axle. Two-circuit service brake is controlled by the REXROTH hydraulic system. Parking brake is mechanically locked, the electro-hydraulic system is used for its unlocking. In case of pressure failure, the brake activates automatically and stops the tractor.
Frame
Front and rare frame: Welded from high-strength steel (S690QL) plates.
- Frame bending up to 45°, 15° frame swing with locking option
Winch EQUUS 2BN
Even the basic version of in-house produced two-drum reel features a transmission with spur gear, which is truly a top forestry reel. Its simple design and quality materials ensure a long useful life without significant demands concerning its maintenance. The reel is powered by DANFOSS hydraulic motor with automatic control in order to achieve better working efficiency. The reel provides a towing force of 10 tonnes, which can be optionally increased up to 16 tonnes. The drums provide the capacity of 2 x 115–160 m (Ø14 mm). The reel has two speeds, the maximum speed amounts to 1.35 m/s. Hydraulic unwinding of the rope can be ordered as a special option: hydraulic motors drive the pulleys and the pulleys smoothly pull the ropes out of the reel drum, making the handling of heavy steel rope easier.
HAFO auxiliary reel can be also installed on request. It is used to pull the heavy wire rope using a nylon rope. The total length of the nylon rope can be up to 350 m. As an option, you can also get special features for the reel, namely the smooth start of winding, winding completion and adjusting the speed of winding/unwinding. Another innovation is a pressure roller in the reel drum which ensures the optimum winding of the rope: it forms regular loops during winding, resulting in longer rope life.
Crane EQUUS
EQUUS hydraulic arms of our own design belong to heavy-duty hydraulic arms and are designed for the most demanding operating conditions. Their robust construction allows for trouble-free handling and dragging of timber. We focus on long useful life and ease of maintenance and service. We can supply various lengths of arms, angles and designs. Each function of a hydraulic arm can be individually adjusted: speed, starting and finishing behaviour, sensitivity of the joysticks, etc.
Hydraulic arms feature a double telescope and the reach of 7.5 m, 8.2 m and 9.1 m. Lifting torque can be 120 kN or 140 kN. Hydraulic arm may also have a floating position if it is necessary to tow it, etc. The hydraulic arm features a rotator, link and Gripen 035 grapple. On request, we can supply link with double brake and various types of grapples. The hydraulic arm is also equipped with a trunk support and 1 LED light to illuminate the grapple. For a surcharge, you can get 2 LED lights on the sides of the hydraulic arm too.
Rear shield
The folding rear shield is made of a high-strength material. The upper edge of the shield is equipped with rigging fixtures. Extremely strong spherical rope pulleys are also a part of the rear shield. Customers can also choose a shield with a self-lifting shield for lifting pulleys to the height of almost 2.3 m. When lifted, the lower edge of the shield is at the optimum height to maintain good ground clearance and a large enough approach angle allowing to smoothly cope with steep slopes when reversing. The baseline width of the rear shield is 2400 mm. The following rear shields can be selected: The basic width of the rear shield is 2400 mm. The following rear shields can be selected:
Front blade
Folding front blade with reinforced bottom bar and timber barriers. Thanks to the high lift of the blade, the tractor has large approach angle, which is a great advantage when running downhill from steep slopes. Several types and widths of the blade are available. Optionally, tool boxes or log gripping fixtures can be mounted on the front blade. It is also possible to increase its lifting force to 6 tonnes. On request, a special (planing) front blade can also be supplied. It can be rotated around the horizontal axis by means of 2 hydraulic cylinders according to the slope of the terrain. In the standard version, the front blade is equipped with a chainsaw holder. The baseline width of the front blade is 2200 mm. The following front blades can be selected:
Clambunk
The rear shield can be optionally equipped with our in-house produced clambunk. The hydraulic cylinder-operated system serves as a holder for timber hauling. Standard feature of the clambunk is the automatic clamping function of the jaws, which ensures that the timber is always gripped firmly when being dragged. There is a choice of a clambunk with the loading area of 0.8 sq. m or a larger one with the area of 1.2 sq. m, and it can be either non-removable or removable with a quick-release coupler.
Remote control
The HBC remote control is handy and practical, especially for use in forestry. The remote control allows to control all functions of the reel, rear shield, engine revs, engine START/STOP.
