- Model CB12 - Commercial Bins



Offering more roof options – including peak load capacity of up to 50,000 lbs. (22,680 kg) on Chief’s larger bins! Chief offers a wide range of standard and optional roofs to meet your desired peak load capacity for your specific operation and handle snow loads for your geographic location.  Included is the optional 50K roof which can increase peak load capacity to 50,000 lbs (22,680 kg) on CB30 and CB34 bins.

Peak loads may eliminate the need for an additional support tower and catwalk on 50k roofs.

50K roofs with a 6’ (1.82m) or 12’ (3.65m) peak ring will support most conveyors with capacity up to 60,000 BPH (1,524 MTH). This negates spanning a catwalk/truss across the bin roof and installing an additional support tower and catwalk.

50K roof promotes faster fill times

With its larger peak load capacities, a 50K roof with a 12’ (3.65m) peak ring will allow customers to use larger capacity conveyors for quicker fill times.

Roof panels feature interlocking “J” rib design

Roof panels are of high quality galvanized steel with a 2.5” (6.35 cm) interlocking “J” rib design for outstanding strength and reduce construction time.

Grain entrapment prevention

All Chief bins come equipped with anchorage points at the bin peak and manhole to provide tie-off points for anyone entering the bin.
