Quality standards and certifications

We test what will be proven in practice. The waste and recycling container manufacture is inspected every year from scratch by an independent institute. In addition, the specified in-house monitoring of manufacturing and materials must be conducted on an ongoing basis. This guarantees a consistently high quality level. New developments are also reliably checked for quality and serviceability.

Drop Test - A container filled with a 200 lb weight is dropped from a 3 foot height multiple times in free fall on a level, rigid impact surface straight or on the front edge.

Wheel Gear Test - The wheel gear of a container filled with over 300 lbs is run continuously for 24 hours on a special rig. This is equivalent to a running distance of approximately 60 miles.

Ball Impact Test - A 10 lb steel cylinder drops multiple times at -4°F from a height of 3 ft via a cylindrical guide precisely on edges, hinges and other delicate points on the container.

Curb / Step Travel Test - A container filled with over 300 lbs impacts 1,000 times, from a height of 7 inches on to a level, rigid surface. This means that the running gear sustains repeated blows on the wheels and axles.

Wetting Agent Bath Test - To check for the formation of cracks due to tensions, the containers are submerged in a wetting agent bath (volume proportion of 2-3%) for a test duration of 48 hours at approximately 150°F.

Heated Storage - The containers are stored upright and without load in a convection oven at approximately 190°F for 3 days. The dimensional changes which occur due to the heated storage must be no more than plus 1.5% and must remain within the tolerances specified for the container.

Material - In the manufacture of carts we source raw materials from reputable suppliers that produce resin meeting the highest quality standards. We combine this high quality virgin resin with post- consumer recycled plastic during manufacturing. SCHAEFER is committed to manufacturing quality carts that are durable, 100% recyclable and meet our commitment to protecting the environment.
