Grain Handling Systems

Chief Bucket Elevators Are Safe and Strong

Poland Steel offers an enhanced head section for reduced impact points and exceptional durability. Our meticulously engineered head section minimizes breakage-causing impact points, ensuring optimal performance and longevity. Each component is manufactured to precise standards using heavy gauge materials, guaranteeing both easy installation and remarkable strength.

Chief bucket elevators are designed with convenience in mind, featuring urethane liners, easy-open hinged discharge inspection doors, and head hood slide clamps. To ensure maximum durability, our crown-faced slide-lagged or vulcanized rubber-lagged head pulleys are crafted to meet the rigorous standards of the mining industry. The laggings are rated as SOF (static conducting, oil resistant, and fire retardant), providing superior protection and performance.

• Chief's exclusive staggered-head hood-to-housing connection ensures a seamless and impact-free transition.

• The discharge baffle, made from ultra-high molecular weight (UHMW) plastic, offers exceptional durability and resistance to sparks.

• Urethane liners, comprised of 0.25" thick blue wire-backed urethane, are custom-cut and securely fastened with heavy-duty flathead hardware. These liners are available for inlet hoppers, discharge hoppers, and elevator head assemblies.

• For heavy-duty applications, ceramic liners consisting of 0.25" ceramic tiles are precisely tailored to fit the prepared surface area and bonded to the steel using adhesive specific to the product.

• To enhance safety, an explosion vent is provided on the back hood side to mitigate the risk of unexpected combustion.

• The bucket elevator head features a no-tool inspection door, facilitating easy access to the discharge throat.

• Ball-bearing or spherical pillow blocks are utilized to withstand the harshest abrasive and corrosive conditions across all elevator sizes. Additionally, all shafts are made of CR 1045 material at a minimum and feature UHMV shaft seals.

Heavy-Duty Commercial Elevator Boot

Chief's robust commercial boot is engineered for exceptional strength and durability. In addition, our bucket elevators feature urethane liners, convenient easy-open hinged discharge inspection doors, and reliable head hood slide clamps.

Standard for 36" Pulleys and Larger

• The frame is constructed using welded and hot-dipped galvanized materials, and it includes structural angle support and 1/4" plates.

• There is a generous 4" clearance below the bottom plate, allowing for easy accessibility.

• To facilitate cleaning, rack, and pinion clean-out doors are provided, which offer convenient access to the boot.

• For added flexibility, the hand wheel can be positioned on either side of the boot.

• A spring-loaded cleanup safety catch ensures that the door remains securely open during maintenance.

• To prevent corrosion, the side shovel pocket cover is equipped with a stainless hinge, and it features a weather and dust-tight seal.

• The side shovel pocket facilitates the feeding of loose grain that may have spilled around the boot area, and the built-in grate prevents foreign objects from entering the elevator.

(Note: Under normal operation, rubber latches should be in place.)

Both the head and boot utilize pillow block bearings, which come in either spherical or ball-bearing designs. The sturdy shafts are made from a minimum of CR 1045 material. The trunking inspection door can be conveniently modified to accommodate dust collection equipment.

• Pillow block bearing
• Trunking inspection door

Assorted Trunk and Manual Boot Sections

Standard for 30" Pulleys and Smaller

• A distinctive hat section bottom panel, positioned 2 1/4" (57.15mm) above ground level, effectively prevents grain from being exposed to shallow water.

• The presence of multiple inspection doors in the boot section facilitates convenient maintenance.

• These inspection doors enable access to a heavy-duty drum or a self-cleaning winged pulley.

• Standard features include 45-degree clean-out sections located on the end panels of each boot section.
  

Easy Chief Elevator Trunk Installations

Various Sections That Fit Your Exact Needs

The end sections of Chief elevator trunks are skillfully engineered and manufactured to ensure a seamless and straightforward installation process.

Trunk sections are offered with bolted flanged seams, which are securely fastened together at the factory to ensure alignment and compatibility. For situations that necessitate it, explosion vents are provided on the up and down leg trunking at 20' (6096mm) intervals. These vents have an opening area that adheres to NFPA guidelines. *

*It is advisable to consult with local authorities to verify the specific explosion venting requirements for each application.

Conveyors

Flexible Chief Horizontal Conveyors

High-Corrosion-Resistant Galvanized

The standard configuration of Chief's horizontal chain conveyors includes intermediate sections that are fully galvanized. These conveyors can be tailored to suit your specific needs by incorporating various features such as exterior gauging, liners, chain types, sprocket options, paddles, and speed settings. By utilizing components manufactured with precise specifications, your Chief chain conveyor will be simple to assemble and deliver durable performance over an extended period.

To ensure exceptional durability, Chief provides fully galvanized material handling systems that can withstand even the harshest corrosive environments. All components are constructed with robustness in mind and are designed to facilitate effortless maintenance.
