Practical Features for Easy Access

Hopper Bin Ladder System
One important feature often overlooked in purchasing feed and holding bins is the side and roof ladders. Brock’s optional Hopper Bin Ladder System is designed to be user-friendly with convenient features like:

  • A convenient handrail (patented) to make users feel confident when stepping from the bin roof to the side ladder.
  • Round rungs with a raised, non-skid surface and are permanently attached to the ladder rail for a hand-filling, secure grip.
  • Versatile stand-off brackets that clamp to the ladder rail, permitting them to be placed wherever needed.
  • Plenty of space between the ladder’s rungs and the bin’s sidewall for your feet.
  • Factory-assembled ladder for quick and easy installation.
  • Bolted safety cage, which is included on ladders over 20 feet (6 meters) in height.

Brock’s Hopper Bin Ladder System – another quality difference BROCK® Feed Bins offer you.

ACCESS PLUS® Hopper Access Door
Brock’s patented ACCESS PLUS® Hopper Access Door makes it easy to clean out the feed bin from ground level. With this Brock innovation, producers no longer have to climb the bin to clean it. Instead, they simply:

  • Open the ACCESS PLUS Door Panel
  • Clean out the bin’s interior
  • Close the ACCESS PLUS Door Panel

Product features include:

  • Door is located in the feed bin’s hopper for convenient, ground-level access to the interior of the feed bin.
  • With the simple removal of a few “T”-handle bolts, the door panel for the ACCESS PLUS lifts out so you can begin the interior cleaning process now being required in some industry sectors.
  • Brock’s ACCESS PLUS opening is “man-sized” to be wider at the top than it is at the bottom for improved work comfort.
  • When cleaning chores are completed, simply replace the door panel and the bolts.
  • The ACCESS PLUS® Door Panel also features a rubber-like seal to re-seal the hopper opening after each use.

ACCESS PLUS — it is another innovative advantage offered by Brock’s feed storage bins and their unique ALL-OUT® Feed Management System.

SPRING-LOCK® Bin Access Lid
Brocks’ SPRING-LOCK® Bin Access Lid for feed bins offers you the benefit of a lid with a positive, spring-aided closing action that resists wind and helps keep snow and rain out. Yet, it’s also easy enough to open with one hand and slides out of the way of the feed truck’s auger. A reinforced collar helps protect the bin from fill auger damage, and a manual hold-down clip is provided for added security when working around or inside the bin or fill hole area. The SPRING-LOCK® Lid easily adjusts to open in almost any direction. It can be operated from ground level or locations away from the bin using an easy-to-grasp handle and long-lasting weather-resistant line.

Accurate WEIGH-MATIC® Scale System

The Digital WEIGH-MATIC® Scale System uses temperature-compensated load cells to give highly accurate weights for feed stored in individual feed bins.

Other ALL-OUT® Feed Bin Features

40-Degree Roof
The 40-degree roof matches the natural incline angle of repose for stored feed to maximize usable feed storage capacity.

HYDROSHIELD® Weather Guard
The HYDROSHIELD® Weather Guard directs moisture to drip off the bin’s sidewall and keeps it off the bin’s hopper and boot.

Manual Boot Slide Actuator

The Manual Boot Slide Actuator from Brock helps producers easily open and close the feed bin boot slide without having to physically crawl under, around, or through the feed bin’s leg and hopper support bracing system.

  • Telescoping handle extends from 5 to 8 feet (1.5 to 2.5 meters) to allow the actuator to be operated from outside the feed bin’s leg and brace area.
  • Easy-to-operate rack and pinion design quickly opens or closes boot slides in just over two turns.
  • Opener can be installed for either right- or left-hand operation.
  • Single and twin-boot versions available.
Feed Bin Boots & Transitions
BROCK® Feed Bins offer producers the choice of either 16- or 25-inch (406- or 635-mm) diameter hopper openings and boot transitions for attaching the feed delivery auger system to the feed bin.
FLEX-AUGER® Conveying Systems
FLEX-AUGER® Conveying Systems — The Industry Standard Brock’s FLEX-AUGER® Coreless Auger Feed Delivery System was invented in 1961. In the years since then, Brock’s FLEX-AUGER System has proven to be the most reliable and best system ever devised to deliver feed.
Feed Bin Ladder Security Door
This economical Ladder Security Door helps to restrict unauthorized access to the outside ladder on feed or grain storage bins and silos.
Feed Bin Hopper Valve Kit
Brock’s unique Hopper Valve Kit offers an alternate way to easily get small amounts of feed or other stored materials out of a hopper-bottom bin.
Rigid Auger Conveying Systems

Brock offers a choice of either a 4- or 6-inch (102- or 152-mm) diameter auger system for limited feed handling and grain moving applications. Both rigid […]
Grain Spreaders
Brock’s Grain Spreaders can evenly distribute grain as the bin is filled for optimum drying and uniform aeration.
