FORESTRY TRAILERS/GRAPPLE LOADERS
•
There are different types of forestry trailers that can be connected to the tractor’s towing de-
vice and smaller trailers that can be connected to a vehicle with a ball coupling. No matter
which trailer you have, it is important to think about safety.
•
Follow the safety information in the forestry trailer’s or crane’s instruction manual. It is the
user’s responsibility to read through the instructions and comply with them. For attachments
connected to tractors, read the tractor's operating manual.
•
Always check the performance of the used machine combination (trailer and crane) to help en-
sure safety and functionality. Grease moving parts, and check that all nuts and bolts are tightened.
•
Check tyre pressure - see info on the sidewalls of the tyres. Do not exceed the maximum pressure!
•
Never overload the trailer!
•
The trailer must not be loaded above the height of the headboard!
•
Never leave the driver’s seat until the brakes on the towing vehicle have been engaged.
•
The risk area is 25 metres. Only the operator is allowed to be within the risk area while the
trailer is in use.
•
Do not leave a loaded trailer parked unsupervised.
•
When unhitching the trailer, it must be empty and on a level surface with the trailer wheels
secured using suitable brake blocks.
•
In an emergency, stop the tractor to stop the movements of the forestry trailer.
•
There is a risk of suspended loads being dropped if the oil supply to the crane is disrupted.
First lower the lifting arm, then the articulated boom and then unload the grapple.
•
The tractor should be fitted with an ABE2 or ABE3 fire extinguisher. Please contact your insur-
ance company for details.
•
The timber trailer’s towing device must always be checked. Regularly check the coupling for
wear and tear. Do not overload the maximum pressure and tensile load of the ball coupling.
•
The forestry trailer's noise level does not exceed 70 dB (A).
•
Exercise caution when working with equipment with hydraulic hoses as the oil under pres-
sure can penetrate skin. Immediately seek medical attention if this should occur.
•
The trailer is not equipped with lights and is only intended to be used in daylight. If necessary,
the trailer can be fitted with a magnetic rear light. If the load is wider than the tractor (200 mm
laterally) when it is dark outside, it must be fitted with approved white reflectors at the front.
•
An SMV sign must be attached when travelling on public roads.
•
EU regulations stipulate how fast a rig with a non-brake trailer is allowed to go. Comply with
these regulations. The maximum speed for a full load is 30 km/h.
•
Kellfri is not liable for any modifications, changes or rebuilds carried out by customers. The
controls are placed in optimal position with tractor/ATV. Warning! Hydraulic hoses must not
be attached inside the cab. When operating the crane, the valve block package must be
placed in a protected place, at the crane foot or behind the trailer.
•
Connect the grapple loader valve block pressure and return hoses correctly. Make sure the
pressure and return hoses are connected correctly. The valve block may be damaged if the
hoses are connected incorrectly.
•
Ensure that the crane is fitted correctly and securely.
•
The crane must not be used when the trailer is in motion.
•
The stabiliser must be used when the crane is in use. Make sure the trailer and stabiliser are
stable on solid level ground.
•
When moving the trailer, remember to lift up the stabilisers.
•
The permitted lifting capacity must not be exceeded. The gripper, rotator and any attachment
that is connected to the tractor are always considered part of the load.
•
Never allow inexperienced personnel to operate the crane.
