Introduction

When performing forestal hauling operations, tree trunks, stalks or logs, etc. need to be fastened to a

towing rope using sling gear (e.g. choker chains, choker ropes) in order to haul them out of the stand.

Such gear can be of various designs.

Test and condition requirements need to be defined in a standard for such sling gear so that when they

are fulfilled the sling gear can absorb the forces acting on it without breaking. Sling gear for forestal

hauling operations is subject to loads different from those acting on sling gear for lifting applications or

cranes. It is necessary to formulate requirements for sling gear for forestal hauling operations in order to

meet the needs of this situation.

3 Terms and definitions

For the purposes of this document, the terms and definitions given in ISO 19472 and EN 16517 and the

following apply.
3.1
rope-assisted felling

felling operation where the traction force of a logging winch is used to maintain the direction of felling

EXAMPLE In cases of safety felling or for felling in another direction as driven by gravity.

Note 1 to entry: This provides safety-relevant and ergonomic advantages.
3.2
choker rope

rope that is tied around the wood to be moved during hauling and held by a choker hook mounted on the

hauling rope

Note 1 to entry: Choker ropes can be manufactured from steel wire or of synthetic fibres.

3.3
choker chain

short chain piece, which has a sling hook at one end and may have an insertion pin at the other end and

which serves for moving wood in hauling operations while it is held by a rope slide eyeletmounted on a

hauling rope

Note 1 to entry: To move wood, the choker chain is joined to a rope slide eyelet running on the hauling rope and

tied around the wood to be moved during hauling.
Note 2 to entry: Choker chains have a length of approx. 2 m to 3 m.
3.4
tree towing rope

synthetic fibre or wire rope with loops at the ends, which is joined via shackles to the tree and to the rope

of a logging winch

Note 1 to entry: Tree towing ropes made of synthetic fibres having a sheathing are usually used when laced.

3.5
laced application of tree towing ropes
lark’s head

application in which the tree towing rope is placed around the tree forming a tightening noose usually

using a shackle
3.6
two-string application of tree towing ropes

application in which the tree towing rope is placed around the tree and in which both loops of the tree

towing rope are inserted in a shackle
3.7
shackle

sling gear, comprising two quick-release individual elements, a shackle body and a bolt, for connecting

the load directly to a hauling device or when using other sling gear
