The Main Features of the Walinga Ultra-lite

  • All aluminum long sills
  • Extruded aluminum divider ribs
  • Extruded aluminum roof rail – rain gutter
  • Designed to provide strength where needed the most

Other Features of the Walinga Ultra-lite

  • 100% welded structure
  • pneumatic or auger discharge as well as cubic capacities

  • Hydraulic tubing

All Aluminum Construction

Extremely durable and light-weight aluminum construction.  The only Trailer available with 100% Extruded Base.  Extruded Base allows engineering to incorporate strength where strength is needed.  This is something formed bases can not give you. 

Extruded Components

One piece extruded components offer added strength as well as added piece of mind!  Allowing for “Frame Flex” without compromising rigidity of the unit.

Aluminum Walkway

Aluminum Expanded Metal walkways offer easy access to entire top side of the trailer.

Hydraulic Controls

Easily accessible as well as easy to understand and operate, using hydraulic fittings that promote good fluid flow efficiencies.

Heavy Duty Bearings

Walinga trailers are built to last. They’ve taken the time to make sure even the little things are going to work well day in and day out.

Heavy Duty Hydraulic Tubing

Heavy duty hydraulic tubing ensures the hydraulic system performs 100% and lasts the lifetime of the trailer.

D.O.T. Lighting

D.O.T. lighting ensures everyone around you can see you in all conditions.

Spring Mounted Motors

Spring Mounted motors were developed to provide longer life of the key components.  Coupled with our Unique Spline Inserts motors and bearings last longer and are easier to change out.  A Walinga Exclusive!

All Bulk Discharge Systems

Walinga Inc. offers a number of different options when it comes to unloading feed and grain. We offer auger unloading, air unloading, paddle chains and drag chains. Whichever suits your needs! 

Walinga Air Discharge

Air Discharge
Air Discharge
The Walinga Pneumatic discharge system is available on both trucks and semi-trailer hopper tanks. It offers superb handling of all types of feed and grain, particularly dairy and pelleted feeds.

Product is moved to the rear of the unit by a 9 in. (23cm) diameter trough auger and is gravity fed into the hydraulically driven airlock. Product is discharged from the airlock by air pressure and is carried through a 4 in. (100mm), 5 in. (125mm) or 6 in. (150mm) line (flexible hose or fixed stinger/boom) directly into the customers bin. Air discharge systems allow the feed to be moved on a “cushion of air” minimizing pellet damage or break-up of feed, as it is discharged into the feed bin.

Walinga Air Discharge System

The Walinga Pneumatic discharge system utilizes the Walinga designed and developed Super Duty Positive Displacement Blower, as well as the Walinga designed and developed Cast Iron Airlock.

Walinga Positive Displacement Blower
Model 510 & 614 Blowers

The Walinga Blower is a precision machined, Positive Displacement design blower. Hard chrome internal surfaces provide for greater wear resistance in transfer applications. The Walinga blower is available in two prime sizes: Model 510-1100 cfm capacity and; Model 614-1800 cfm capacity.

Walinga Blowers continued
The positive displacement blower provides the system with constant air at varying pressures allowing the operator a greater range of flexibility in loading and unloading of products. For every revolution of the impellors there is a positive displacement of air into the discharge line. This constant flow of air helps move the product on a cushion of air providing for a more consistent delivery of product.

The Walinga blower is the heart of the pneumatic system. The precision machined, cast iron housing, end plates and impellors are evidence of a rugged yet top performing component of the pneumatic discharge system.

Walinga Rotary Vein Airlocks
Model AL 1314-4 Airlock

The Walinga Airlock is a precision-machined cast iron housing hydraulically driven airlock. The Walinga manufactured airlocks have been designed to provide maximum performance, with minimal product damage.

The fabricated steel rotor is available in 8 or 10 vane configurations with stainless steel, carbon steel knife edge or composite rubber adjustable tips. The injets and outlet are designed to allow for a freer flow of material providing for maximum capacity and minimal product damage.

Walinga Rotary Airlocks continued

The airlock is driven by a pressure protected, variable speed, hydraulic motor. Reversible rotation capabilities of the hydraulic system allow the operator to easily remove foreign objects, which may have ended up in the feed / grain.

Model Line Size Capacity
Al 1314-4 4 in. .86 cfr.
Al 1314-5 5 in. .86 cfr.
Al 1314-6 6 in. 1.8 cfr.
Al 1314-7 7 in. 2.2 cfr.

Walinga Auger Discharge

The Walinga Auger discharge system provides the operator with the ability to handle multiple products on any load. All augers are fabricated “in house” in order to provide optimal quality control.

All trough augers are installed on a “UHMW” wear liner to provide maximum durability along with minimum maintenance. The Auger Transitions are designed to provide free flow of material from Trough to Vertical to Boom. The result — minimum product damage with maximum flow rate.

Auger Discharge

The Walinga design employs a 9in. (23cm) diameter trough auger with helicoid flighting on a 2 1/2 in (63mm) diameter shaft. Direct drive by a heavy duty, spring mounted high torque hydraulic motor incorporates automatic surge overload protection that controls the speed of the discharge augers. The design includes a heavy duty thrust bearing on the drive end and hanger bearing at the discharge end. A plastic (UHMW) liner in the auger trough is supplied to provide a tighter fit between auger and trough as well as prolonged life of trough.

Boom Rotation

The rotation of the Boom is by means of RC80 primary reduction and RD50 secondary reduction drives. Rated strength is 14,000 lbs. (6343 kg). Hydraulic over load protection is provided through a cross over relief valve.

Inverted "V" Gates

Inverted “V” gates allow each compartment to be individually discharged of its load through selective operation of the gates. Manual type rack & pinion are standard. Air operated gates are offered as an option. With the inverted “V” gates, the gates can be closed “against the load.”

Auger Discharge
Auger Discharge

Walinga Paddle Discharge

Paddle Discharge
Paddle Discharge
The Walinga designed paddle discharge is available in two styles.

Double Chain flat paddle with horizontal sliding gates, which is ideal for typical Dairy “Sticky” feeds or in a 1/2 moon style Single chain paddle with Inverted “V” style gates, which is ideal for pelleted feeds and especially designed for “range cubes” or “cow cakes.”

Horizontal Gates

Both systems incorporate the Walinga direct drive, heavy duty, spring mounted, high-torque hydraulic motor design. This system allows for better speed control of the discharge system and longer component life. Wear liners are also incorporated into the trough and paddle boom to provide you with better clean-out and longer wear life.

Paddle Style Aluminum Boom

With the many variables in the different types of feed, you need to have the equipment to handle these variables. Walinga offers you these variables in the three different types of discharge systems. Auger discharge, Paddle discharge and Air discharge.

Paddle Style Hopper Trailer

Double Chain flat paddle with horizontal sliding gates, which is ideal for typical Dairy “Sticky” feeds or in a 1/2 moon style Single chain paddle with Inverted “V” style gates, which is ideal for pelleted feeds and especially designed for “range cubes” or “cow cakes.”

Transition Head

Double Chain flat paddle with horizontal sliding gates, which is ideal for typical Dairy “Sticky” feeds or in a 1/2 moon style Single chain paddle with Inverted “V” style gates, which is ideal for pelleted feeds and especially designed for “range cubes” or “cow cakes.”
