New equipment to lighten the work load of construction workers.

The objective of this study was to determine whether the 4 pieces of equipment for cutting moulding, cutting reinforcement rods, carrying carpet rolls, and fitting drain pipes can lighten the work load of construction work. The results indicate that the effect of using the new ergonomically designed equipment was positive. The cutter for reinforcement rods proved to be useful, bent back postures decreased by 11%. The carrying of carpet rolls became less loading on the lower and upper extremities. According to the men the work load was lower in fitting drain pipes, especially on the lower extremities and in the neck and shoulder region. The conclusion was reached that work load can be decreased with well-planned equipment, but more attention should be given to personal work methods and habits.
