FIELD OF APLICATION 



The KESLA 200 and 300 -series cranes cover the needs in farming and forestry and 

they are especially useful for loading and lifting round timber, forage, manure, 

sand, loose fertilizer, fertilizer sacks etc. In forestry use the grapple loaders are 

suited for the farmer's own harvesting in thinning stands and also for professional 

work. 

OPERATING PRINCIPLE 

The operator guides the loader movements with a control valve. The valve transfers 

the hydraulic pressure, generated by the tractor, to the hydraulic cylinders of the 

loader, thus bringing about the wanted functions; slewing of booms, lifting of main 

lifting boom, compression of grapple etc. The loader valve is fitted with relief valves 

to prevent overloading of the grapple loader.

Finnhydraulic RS valves 

-4 mechanic levers 

-This RS- control valve is easy to operate, the operator always can keep his hands on the control levers (only the 

stabilizers are operated with separate levers). The extension and grapple are controlled by the ear shaped levers. 

The main levers are on the standard loader pattern. Main lift and slew have a floating position that permits loader 

movement during transportation. When in presence of closed center hydraulics this valve can be converted by 

adding a simple power beyond plug. A shock relief valve protects the whole system and some shock relief valves 

protect vital functions.

KESLA remote controlled winch 

Kesla We1400P winch # 3301296 is remote controlled version for Kesla 200- and 

300-series loaders. 

Technical data: 

-Pulling force 1400 kg/175 bar 

-Speed 27 m/min 

-Wire rope Ø 6 mm / 40 m 

-Weight 45 kg 



The Kesla We1400P remote controlled hydraulic winch is driven by cog-wheel to get the best 

effect. An enclosed valve regulates the winding-up process, the middle position is a motor 

brake position and off position of the drum enables to draw out the wire. The valve is mounted 

with enclosed tubes in a series with the crane’s hydraulic system. 

Wireless managing 

A transmitter regulates the winding-up process, when transmitting breaks, the cog-wheel 

comes to the off position and the wire can be drawn out. The valve is mounted and well 

protected near the engine of the winch. The little receiver is placed inside the cabin for best 

protection and the electric cable is connected to the tractor’s trailer contact. The system is 

developed for the forest industry to manage a demanding environment.



8T, 9T/9HD TRAILERS 

Field of application 

KESLA 8T, 9T/9HD trailers 

are designed to be used 

together with loaders KESLA 

200 – series loaders 

especially for timber 

forwarding in thinning 

stands, but are also well 

suited for professional timber 

hauling. All kinds of timber, 

from firewood stems and 

pulpwood to logs, can be 

transported with the trailers. 

In addition the trailer lends 

itself to transport of round 

bales, if fitted with suitable 

round bale equipment. 

Optional hydraulic drawbar articulation – with 2-cylinders (8T – 1-cylinder) 

The use of the drawbar articulation makes the trailer follow the tractor, thus diminishing the 

damage caused to the growing trees alongside the skid road. Stability of the trailer in slope 

can be increased by turning the bar uphill. Using the drawbar to steer the bogie to run beside 

stones and stumps prevents the trailer from useless inclination. The closer the bogie is, the 

more nimble and more stable in turns is the trailer. Thanks to the drawbar, the loader 

mounted to the trailer will get an extra reach of about 80 cm.

MAIN PARTS OF A TRAILER 



1. Drawbar – optional drawbars in the price list 

2. Parking leg 

3. Hydraulic hoses 

4. Towing eye 

5. Drawbar articulation cylinder – optional

HYDRAULIC DRIVE (9 HD) 

•When engaging the pressure from the valve to the trailer traction, the pressure in the dividing 

block (inside the trailer frame) will be divided to the hydraulic motors (to the drive roller) on 

both sides. The working pressure is also directed to the arm cylinders, which effects the settling 

of the rollers between the tyres. 

•When centering the control valve spool (stopping the trailer traction) the hoses will get 

connected with the tank through the control valve spool. Now also the pressure in the arm 

cylinder (which presses down the drive rollers) will drop to tank pressure and the recoil spring 

inside the cylinder will raise the arm (the drive roller). 

•The control valve shall be fitted with a pressure-relief valve for the working pressure. The max 

pressure of the drive hydraulics is 175 bar. 

When the work pressure hoses are connected to the tractor hydraulics, the pressure-relief is 

usually attended to (in newer tractors about 180 bar.) 

The pressure-relief valve is included in the control valve available as an accessory for the 

KESLA 9HD trailer.

10 H, 10 HD



Hydraulic nave drive (10 ND)



Hydraulic drive with wheel motor (10 ND) 

The hydraulic motor is equipped with a hydraulic one-way clutch. When motors are used, 

pressure is connected to the control line, and the spool inside the motor allows normal oil flow in 

the motor. When control pressure is removed, the spool prevents oil from getting under the 

pistons, the springs keep the pistons inside the cylinder block and the motors go into free rotation 

mode. In a KESLA 10ND trailer, switching pressure is taken through change valves and a 

pressure reducer from the working line, so a separate control line from the tractor is not 

required. Therefore switching into free rotation takes place automatically when pressure 

disappears from the working line. When driving on the road, the drive hydraulics must be 

switched off, unless required in a specific situation. This is because when the trailer brakes 

(accessory) are used, pressure in the working line increases and motors are switched on causing 

a decrease in braking power and premature wear of the brakes.

12MD / 12MDH 

KESLA 12MD is equipped with sturdy mechanical drive with huge 5.3 tons traction force. 

Transmission is fully mechanical with oil-bathed chain transmission in bogies. Power 

transmission is to be connected to ground-speed PTO of tractor (type and tire size of tractor 

has to be informed so that right gear ratio can be adjusted). 

KESLA 12MDH has hydrostatic-mechanical power transmission to be used with tractors 

without ground-speed PTO (to be connected to 540rpm PTO). It gives 4.8 tons traction 

force. Hydraulic system of the trailer is equipped with 71cm3 variable-displacement pump 

(Rexroth) and driving motor Danfoss OMV 400. Oil flow and driving direction are controlled 

by electrical valve. Oil tank of 120 liters (31.7 gal US) with return filter is in inside the loader 

mounting column. The hydraulic system of trailer can be used also for loader. 

Trailers are featured with a unique traction release clutch, witch means that trailer doesn’t 

restrict the driving speed on roads. 


• Robust single main beam tube of 250x250x10 mm 


• Sturdy, movable head rack height of 162 cm 

• Large load capacity 

• Movable front & rear crossbeams

• Rocking beam joints with durable bushings 

• Wheel spindles with high quality conical bearings 






Power transmission of 12MD

The transmission mechanism of KESLA 12 MD 

can only be connected to a tractor with 

ground-speed PTO, and the transmission ratio 

of the trailer must be suited for the tractor in 

question. 

1: Reduction gear 

2: Drive gear 

3: Chain gear in oil 

bath 

4: Traction release 

clutch

1 

When driving with ground-speed PTO 

engaged, the torque from the tractor is 

transmitted through the transmission line to 

the reduction gear of the trailer, and through 

an overload switch to the release clutch and 

the drive gear. The transmission ratio is to be 

made suitable for the tractor in the reduction 

gear. A disc coupling with the torque adjusted 

to be equal to the maximum traction power 

operates as an overload switch. The release 

clutch can be used to disengage the 

transmission when faster speed is needed 

(driving on road). The drive gear is equipped 

with a differential gear. 

From the drive gear the torque is transferred 

to both bogies with drive shafts that drive the 

wheels through the chain gear. The roller 

chains are oil immersed and equipped with 

tighteners.

While the power transmission 

mechanism of KESLA 12 MD is fully 

mechanical, KESLA 12 MDH 

features a hydrostatic-mechanical 

power transmission. Components 

are similar but instead of drive shaft 

from ground-speed PTO there is a 

variable displacement hydraulic 

pump (Rexroth 71cc) and drive 

motor (Danfoss OMV 400). This 

systems features adjustable gear 

ratio and is to be fitted to any 

tractor with 540rpm PTO.
