Skidder EQUUS 175N UN

the best-selling model from the entire EQUUS

This tractor belongs among the top European 4-wheel forestry special tractors with hydraulic arm. Forestry tractor EQUUS 175N UN is designed for timber dragging using a reel with the towing force of up to 16 tonnes and timber harvesting using a hydraulic arm and a clambunk.

By its dimensions and engine performance, this model fits into the mid-range class, but its axles, cardan joints, reel, hydraulic arm, etc. point to the heavy duty class, making this machine a high performance skidded with low fuel consumption. This machine has the lowest centre of gravity in its class. It has excellent strength and stability.

Engine CUMMINS

The CUMMINS engine is suitable for working at lower economical speeds, when it has the most power. The Cummins-designed turbocharger is a key component in achieving exceptional performance and responsiveness for faster cycles. Not only do you get more power - you use less fuel. EGR-free architecture reduces complexity, increases reliability and reduces cooling system space requirements.

Engine – CUMMINS B4.5 Stage V

Engine Power: 129 kW (175 hp) at 2200 rpm
Torque: 780 Nm at 1500 rpm
Type: diesel, direct injection (Electronic Common Rail)
Capacity: 4,5 l, 4 cylinders
Volume of tank: fuel 170 l, AdBlue 37 l

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

Safe cabin

The safe cabin with FOPS, ROPS, OPS certificates and large safety glasses ensures maximum visibility and overview of the workplace. Tilting forward facilitates service access and increases comfort. Two side doors ensure convenient entry and exit and also serve as emergency exits. The GRAMMER suspension seat with a rotating work station and joystick offers comfortable control of all machine functions. The MP3/USB/Bluetooth radio – Handsfree is also standard. Air conditioning with WEBASTO independent heating and effective air filtration provide a clean working environment even in demanding conditions. The cabin is equipped with 8 LED work lights.

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:
