Silent nights
February 28th 2008 Deliveries at night to retail stores are not popular with local residents due to the noise of pallet trucks running over uneven surfaces. The situation for a Spanish supermarket chain was so bad that it asked Yale to design and manufacture a much quieter pallet truck. The result is the Yale MP16S Low Noise powered pallet truck which features a patented triple wheel design and noise reduction measures.
Engineers at the warehouse equipment development centre in Italy isolated all the potential noise generating points on the standard pallet truck and developed a solution for night time deliveries and other applications where noise is a major consideration, in the form of the Yale MP 16 Low Noise powered pallet truck.
The noise generating points were assessed for sound deadening treatment, including noise-free magnetic battering cover fastenings, noise reduction strips to dampen mechanical impact, sound absorbing material on the motor cover and hydraulic pump and noise absorbing paint applied to the chassis.
While these measures greatly reduced the unwanted noise, the major breakthrough came with the design for a new offset third wheel running in parallel with the existing tandem wheels at the front of the forks. The patented design means that the quiet running wheels are always on the floor surface and cannot drop into the joints between pavers, concrete blocks or similar uneven surfaces found outside retail premises.
