Taking time to photograph an installation for the blog after a long days work is not always at the forefront of our installation teams’ mind. On this particular occasion they even managed to get an artistic picture of the chute from the the third floor looking down.
This shot shows the plywood floor formed in the chute shaft at floor level. These were build by us at each floor level to eliminate working at height. the chute was built up from the bottom and at each floor level we installed joist hangars, joists (suitably **censored**ed to accommodate the 400mm chute) and a 22mm plywood floor. This allowed a secure footing to plant an access platform, off which we worked to build the joist floor at the next level. Although our installers are all harness and fall restraint trained, this avoids working in a large open shaft and eliminates the possibility of falling except from the 2m high platform. Sometimes the chute enclosures or shafts are too small to accommodate a platform or podium and we have to use step ladders. All our installers are platform and step ladder trained.
This particular application intend sending laundry mostly as individual items rather than bagging it prior to depositing, therefore the 400mm diameter size was best suited to their needs. If the laundry is going to be bagged before depositing, then additional strengthening and deceleration measures are required, and we recommend a minimum 500mm diameter chute.
You will notice from the pictures that there are TY branches off the main chute at each door level. This is a solution to prevent operatives from having their arm in the main chute drop when depositing laundry, and risking injury from items deposited through doors above. The alternative to this option is electronic self locking doors, which prevent more than one door being opened at once. When any door is opened, a red LED lights on all other doors and they automatically lock. This simple, non-mechanical solution is much better if **censored**e allows and provides a system that requires virtually no maintenance, testing or future service contract. Unlike the electronic solution.
This installation is one of our largest commercial installations with seven doors. The chute was installed into a brain rehabilitation unit in the North East in Aug 2013.
