4B Group products

CC-S® is a range of heavy-duty CC style elevator buckets designed to outperform other agricultural buckets by offering greater capacities, longer life, and cleaner discharges.  Unique Iceberg® Edge design with stronger front lip and maximum material thickness.  With the CC-S® series stackable design, there is the added benefit of substantial freight and storage space savings.  The complete CC-S® range of 35 different sizes are molded from premium virgin white HDPE (nylon and urethane available) for ultimate strength and durability.

The JUMBO™ CC-S® is an ultra heavy duty version of the CC-S heavy duty elevator bucket, and part of 4B`s High Efficiency™ bucket range.  It is intended for the most severe applications, including port terminals, ethanol plants and highly abrasive materials.  It offers the greatest capacity and thickest front lip, corners and walls available.  The unique Iceberg® Edge front face delivers impact resistance and long life.  It shares the proven geometry and design features of the CC-S, including the benefit of stackability, which saves on freight costs and storage space.  The JUMBO CC-S is molded from virgin HDPE (nylon and urethane also available) for ultra heavy duty strength and durability.

Like the standard JUMBO CC-S, the low profile version has the greatest capacity and thickest front lip, corners and walls available.  These buckets are manufactured to mount on nominal projection less "one inch" for increased capacity.  4B conservatively uses water level to calculate usable capacity on our low profile buckets. Unique to the industry, 4B manufactures the JUMBO CC-S low profile style as a one piece molded unit, not a cut-down version of the standard elevator bucket.  The molded design ensures consistent and accurate bucket dimensions.

#1 Norway bolts are the most common style in the U.S. grain industry. The square shoulder under the flat head of the Norway bolt helps prevent spinning during installation (square peg in a round hole principle).  4B #1 Norway bolts meet or exceed Grade 2 standards for load, yield and tensile strength.

The fanged elevator bolt is characterized by two sharp teeth that are intended to penetrate the carcass of the elevator belt. Once the teeth penetrate the belt, they help keep the bolt from spinning which easily allows the lock nut to be tightened.

Euro DIN 15237 elevator bolts have a concave head and two lugs on the underside to help prevent rotation when tightening. Popular throughout Europe for the last 30 years, this fastening system is intended for the attachment of pressed steel elevator buckets incorporating recessed bolt holes. The recessed area surrounding the bolt hole is intended to accommodate the similarly domed surface under the bolt head. Because of this domed area under the bolt head, these bolts are not recommended for flat back plastic buckets, especially on thinner belts.

Reference 70™ (REF 70™) are ISO grade 5.8 elevator bolts with a concave head and four lugs on the underside to help prevent rotation when tightening.  The REF 70™ bolt, when coupled with the special oval washer, is ideal for steel elevator buckets in heavy-duty industrial applications on larger diameter pulleys over 20 inches in diameter. Because of this domed area under the bolt head, these bolts are not recommended for flat back plastic buckets, especially on thinner belts.

The Touchswitch is an electronic limit switch. When a belt misaligns or a pulley moves over and contacts the sensor, the built in solid-state electronic circuitry detects the lateral force of the belt or pulley and activates a voltage free relay contact. This relay contact is used to immediately alarm and shutdown the machine.
