                      SECURING OF ROUNDWOOD LOADS


With cross-loading of roundwood discontinued in the UK, it has become apparent
that longitudinal loading of roundwood may, under certain circumstances (i.e. severe
braking etc), result in increased risk of part of a load moving forwards and possibly
striking the vehicle cab and injuring drivers. Accordingly, consideration has been
given to means of improving load restraint and driver safety. The question of securing
the booms of lorry-mounted timber loaders has also been addressed. The following
recommendations are made following discussion and consultation within the forest
products and specialist timber haulage sectors.

Proposed recommendation

These recommendations are for minimum standards to secure roundwood loads on
road vehicles. It must be noted that the vehicle driver is ultimately responsible for
ensuring that the load is safe and secure. Consequently, under certain
circumstances, the driver may decide that additional restraint is required.

Throughout this document reference is made to straps, it is essential that
appropriately rated straps, which are in a satisfactory condition, are used to secure
roundwood loads. It should be noted that lashings (straps, webbing, chains etc) form
part of an overall load restraint system; other components include headboards,
stanchions, fixed bearers etc. Friction between the load and the vehicle floor also
contributes to restraint.

This document should be read in conjunction with;

Transport, 2002.

Road haulage of round timber Code of Practice (3rd edition, 2003)

After careful consideration and in the interests of making a practical and
unambiguous recommendation, the following is proposed;

For roundwood with bark attached;

       For vehicles fitted with cab-height headboards, each bay/bunk of roundwood
        should be secured with at least one appropriately rated strap.

       For vehicles fitted with both front-mounted timber loaders and aggressive
        bolsters, each bay/bunk should be secured with one appropriately rated

       For all other vehicles not fitted with a cab-height headboard, the bay/bunk
        nearest the cab should be secured with two appropriately rated straps, the
        other bunks should each be secured with one appropriately rated strap.

                                                                             Page 1 of 2
For debarked roundwood (bark removed);

In view of the potentially slippery nature of debarked roundwood, it is recommended
that all debarked roundwood loads, irrespective of vehicle type/configuration, should
be secured by a minimum of two appropriately rated straps per bay/bunk.

Securing of lorry-mounted timber loaders.

The question of the most appropriate method of securing the booms of lorry-
mounted timber loaders on loaded vehicles has also been considered and the
following recommendation is made;

      Under normal circumstances, the boom/jib of the loader should be bedded
       into the top of the roundwood load in which a valley or trough has been
       formed and it should be strapped in this position. In this case, it is not
       considered necessary to strap the load and the boom separately. However, if
       for capacity reasons, it is necessary to build the load level with the top of the
       bolsters, the load should be strapped independently of the boom/jib, which
       should be strapped separately, to ensure adequate load restraint.
