CONSTRUCTION OF ALUMINUM WALL RACK. A RESEARCH PROJECT TOPIC ON CHEMICAL ENGINEERING
This project was constructed with the desired materials of construction. The materials include aluminum, glass and wood. Aluminum was used in forming the skeleton of the structure, glass was used for the doors while wood was used in the sides, top, base and partitions.
After building the skeleton of the structure with aluminum, other materials were used and made up the complete structure. Materials like glass and wood.
Among the different types of glass available, the thick glass was used due to the fact that it offers greater resistance to hit than some thin glasses through the resistances is not much and can be broken by a fore more than fitty Newton – 50N. The glass was cut into the measured dimensions by the equipment called “diamond”. The diamond divides the glass perfectly according to the marker.
The wood used in the construction was cut with the aid of a saw and the edges smoothed with a file. Both the wood and glass were held firm in the aluminum rail with the aid of a projected rubber.
The aluminum profiles were cut with the aid of an electrically powered machine cutter though manual cutters are available but electrical cutter reduces efforts.
Racks are storage systems used in industries, homes, institutions etc.
Rock of interest of this project is the type of rack found in homes and some other institution. This is a minim rack or wall rack as it is normally called. This rack is hung on walls and partitioned within small ranges where material of small size can be kept.
Industries steel storage racks as they are known today did not exist 35 y ears ago. Rail road cars filled with material in cardboard cartons were hand unloaded into four wheeled platform tracks that were pushed to the elevator of a multistioned ware house and the cartons hand unloaded into stacks on floors with 10 metres high ceilings. People used the same various trucks to assemble orders from the various stacks pushing the loaded truck to the elevator and then to the shipping dock where they were unloaded into vehicles for store delivery. Such rudimentary distribution has been radically changed by some relatively simple innovations.
Forklift trucks have replaced man powered vehicles and loading methods. They have been on the materials handling stage since the early 1900s and received their biggest impetus during World War II when forklifts were the logistical workhorses of the army and navy.
Unit loads of 2000 – 400016 that are easily picked up and transported by forklift trucks make highway trailer loading and unloading matter of minutes compared to the many hours for the hand unload method.
