The use of mobile cable yarders is spreading over worldwide and is ample and diverse.

Our machinery stands out for its extreme strength and reliability. In very close contact with our clients we keep developing and optimising our machines, using modern techniques and tools. Ease of setup and operation, as well as simplicity of service characterize our machines and allow to reach high safety standards.

We use only certified materials and high quality components, since we consider the machine’s long life a very important value. Thanks to advanced drive and control techniques, our machines have low running costs and grant a continuous, even and fast operating mode.

VALENTINI enterprise has always been a pioneer in the field of cable yarders’ automation and keeps

developing technological solutions for its machines. In particular, the “automatic path” system and the safety devices’ control system are extremely reliable devices which allow an efficient and safe work cycle. Our cable yarders can operate automatically along the whole line length and be radio controlled just in the loading and unloading points by each operator. Thanks to the accurate and constant control of all the values such as engine’s data, maximum pressure, maximum speed, cables’ strain, slowdown points along the line etc., high speeds and therefore more production efficiency can be achieved.

As a general rule, 2 to 3 operators work with a VALENTINI cable yarder: the one who works in the unloading point can also use a timber loader or a harvester; the other one or two operators (according to the jobs’ difficulty or to the carriage used) work in the loading area in the forest.

Since our machines are extremely robust, the carriages used with them are often double type for the full suspension of the load: they can work downhill, uphill or on flatland. Thanks to the full suspension of the logs, soil damages and dirt on timber are avoided; furthermore, this type of carriage allows higher translation speed on long lines.

Working in very close contact with our clients, our aim is to provide the right solution for matching the variables that they indicate, such as terrain conditions of the sites where they will be working, load size and type, sites’ accessibility and other peculiar requirements.

The VALENTINI cable yarders’ drums are well visible but nevertheless well protected, since when the unloading point’s conditions are particularly difficult some log can get a bit closer to the machine.
On most new models it is not necessary to install a cable guide device for the mainline: the tower is simply equipped with a cable unwinding pulley, which allows to optimise the mainline cable’s tension during its winding and unwinding on the drum. In this way there are no cable slacks and additional safety is provided.

All the models have a radio-controlled safety lowering function for the skyline in case of emergency. In event of skyline overloading the drum’s brake slips in a controlled way, in order to reduce the cable tension and to respect in this way the cable’s safety parameters.

Our machines offer wide possibilities of fine-tuning the automatic path control system, according to the specific harvesting conditions: this allows to work in a more efficient and safer way. Furthermore, an automatic unloading function is being developed.

Cable yarders on tracked undercarriage have major advantages regarding compactness and manoeuvrability. There is no cab and the whole machine is all-round protected, as forestry machinery should always be.
Such a machine can climb for reaching areas that would be unapproachable for a trailer or a truck. These cable yarders are completely radio-controlled, also for the driving functions: in this way no-one will have to be in the danger area while the machine is moving.
Tracked cable yarders can be placed on any ground good enough for bearing the machine’s weight.
For wintertime the tracks can be equipped with special removable ice studs plates, which ensure good grip on ice and snow.

Among the 3-drums cable yarders (+ 1 setup drum, also called universal cable yarders) on tracked undercarriage, we distinguish two groups:
V 850 and V 1000/B10 | compact:
The telescopic tower of the compact models is completely withdrawn inside the machine in transport mode: this allows to keep the machine’s barycenter very low.
These machines are characterized by a very compact construction.
Tower height up to 13 meters.

V1000 | V 1500 | V 1000/R/Power Yarder
This series is convincing especially for its power, speed and tower height.
These models’ tower combines the telescopic system together with the bending system: the tower is raised by a cylinder and pulled out by another one. This allows short setup time and extreme tower height.
The cable drums have a very big diameter, in order to provide constant power and speed, as well as for ensuring a perfect and compact cable winding, with less coils.
Tower height from 12 to 18 meters or from 16 to 23 meters, thanks to the telescopic system.

A particular strength of our company is the bond we have with the machines: this is the reason why we bind the purchase of a machine by a new client or of a new model to a several days’ training with a final certificate for the crew who will be working with the cable yarder.
This means that when a VALENTINI cable yarder is delivered, a basic training begins: this is the first step of our collaboration with the new team that will be in charge of the machine.

Training program:

Basic:

• Knowing and assessing the existing knowledge, setting which methods suit better.
• Job safety and safe setup of the cable yarder.
• Detailed construction of the machine and presentation of all of its parts.
• Theory of the yarding line (setting the cable line, choosing the supports’ type and place, anchoring possibilities, etc.).
• Setting up the yarding line (supports’ setup, anchoring, …).
• Training for avoiding particular risks in the cable yarding area; maintenance and servicing.
• Starting up and beginning to work.
• Training of the crew while working with the cable yarder, in the loading areas and at the machine.
• Dismantling the cable yarding plant (theory).

The basic program usually lasts from 4 to 7 days, according to the machine type. It is concluded with an exam for the cable yarder operators. If at the end of the program the operators’ knowledge is still not adequate for the job, it is possible to agree for continuing with the basic training.
The main purpose of this training is to prevent accidents and for the machine’s warranty, which is valid of course only if the cable yarder is properly used.
When the exam is successfully passed, the cable yarder is officially handed in.

In most countries this training is not officially recognized: it is in the machine owner’s and in its operator’s interest to employ qualified staff. At least two workers need to be trained in working at heights or at least in tree climbing.
A person in charge of the machine should also be chosen in advance.

Specialisation:

• Improving the safety aspects’ knowledge.
• Visit to the yarding site and risk assessment (accidents’ prevention).
• Theory: measuring the line, calculations, supports’ techniques, anchoring techniques, maintenance.
• Management and efficiency assessment.
• Optimization of the ongoing job’s efficiency.
• Final report on safety and efficiency of the yarding site.

This further training is recommended after a few months, for deepening the knowledge learnt thanks to the training and practice. Since cable yarders operation is potentially dangerous and expensive, after some time the company that is using such a machine should take advantage of this specialisation course.

This training is particularly useful for avoiding accidents and for improving the yarding job’s efficiency.
