FEM classification	The European Federation of Materials Handling and Storage Equipment is an association of constructors and experts setting common rules for the design and use of handling equipment, including lifting equipment. To determine the group for your lifting device, winch or block and tackle, three essential parameters are to be taken into account: . Maximum load to be lifted: It includes the weight of the cable and any lifting accessories (hook, etc.) except where these are of a total weight of 5 % or less of the load to be lifted. . Load condition: it determines in what proportions the lifting device is used at maximum load or reduced load. For an exact classification, it is preferably to calculate the average cubic value (k) using the formula below: where : Thus a distinction is made between four characterised load conditions: Light Lifting devises subjected exceptionally to the maximum load and normally to very light loads. k ≤ 0,5 Medium Lifting devises subjected fairly often to the maximum load and normally to light loads. 0,5 < k ≤ 0,63 Heavy Lifting devises subjected frequently to the maximum load and normally to medium loads. 0,63 < k ≤ 0,8 Very heavy Lifting devises subjected regularly to loads close to the maximum load. 0,8 < k ≤ 1 . Operating class: This is the average operating time per day, on the basis of 250 working days a year. The lifting device is considered to be in operation when it is moving; conversely, it is not during stoppage times, between raising and lowering for example.

Forestry winches	A forestry winch is a type of equipment specially designed to facilitate forestry work. This versatile type of pulling/hauling winch is used to pull or move heavy loads across often uneven terrain, for example during operations such as: skidding: the process of pulling logs from the felling area to the access road. selective felling: to assist in the controlled felling of trees by pulling them in a specific direction. loading/unloading: to facilitate the handling of logs onto trailers or lorries. as well as for rescue operations: to free machinery or vehicles that are stuck or bogged down. It is therefore essential for loggers, forest operators and forestry professionals. The forestry winches in our catalogue (FORESTBOX range) are fitted with a petrol engine (2- or 4-stroke) for autonomous operation. Compact and lightweight, they are easily transportable, making them ideal for locations that are difficult or even impossible for machinery to access. Their use optimises productivity and improves working conditions, including operator safety (remote operation by pulling the rope, a roll-back brake system preventing the load from moving backwards). In conclusion, the forestry winch is an essential piece of equipment for professionals in the timber industry. However, it is also suitable for fire and breakdown services in remote areas (vehicle recovery, etc.) as well as for the construction sector on demanding sites (pulling cables or pipes, etc.). It combines power, robustness and versatility, whilst reducing the physical strain of tasks carried out manually by operators.

Thus a distinction is made between four characterised load conditions:

Light

Lifting devises subjected exceptionally to the maximum load and normally to very light loads.

k ≤ 0,5

Medium

Lifting devises subjected fairly often to the maximum load and normally to light loads.

0,5 < k ≤ 0,63

Heavy

Lifting devises subjected frequently to the maximum load and normally to medium loads.

0,63 < k ≤ 0,8

Very heavy

Lifting devises subjected regularly to loads close to the maximum load.

0,8 < k ≤ 1

. Operating class:

This is the average operating time per day, on the basis of 250 working days a year.
The lifting device is considered to be in operation when it is moving; conversely, it is not during stoppage times, between raising and lowering for example.
