Plastic elevator buckets are made from materials like polyethylene
Plastic elevator buckets are made from materials like polyethylene, polyurethane, and nylon. These buckets
have been on the market since approximately the 1950’s and have been very successful since their
introduction in the USA. At present, plastic buckets are widely used, also in Europe, Asia, Australia,
Africa, and South America.
Plastic elevator buckets have a lower weight, are more flexible, and will bend allowing a certain degree of
deformation before breaking. Whereas metal buckets will remain deformed, the plastic buckets will
return into its original shape. When meeting an obstruction the plastic bucket will not cause a spark
like metal may do when meeting tramp material in the bucket elevator. Plastic buckets are lighter
and may allow for lighter belts. In addition, plastic buckets made of such materials as polyurethane
and nylon can offer much longer life than metal buckets leading to lower operational cost.
