Dump Trailers

OJB-industries dump trailers are top of the line dump trailers for the customer who demands quality. Our trailers will match and even outperform any trailer in the industry.

They have a large capacity and an extremely heavy frame. All the trailers have European quality axles with drum brakes which can be hydraulic or air operated. Our tandem is developed by OJB-industries Inc itself and is unique and unmatched in the industry. All our dump bodies have a three inch tapered box which prevents bridging of your product while dumping.


Our new and improved tailgate has mechanical locks which are operated by the tailgate cylinder. The locks prevent leaking of semi liquid materials or grain.
Opening and closing of the tailgate goes hydraulic which runs on your tractor remote.

Wide Body

OJB industries dump wagons have a wide body and an even wider frame. Outside to outside wheels it measures 11’6”. This makes the dump wagon extremely stable and safe to work with.
All OJB industries dump wagons come with a bumper and deluxe tail lights

Boxed-in Tandem

The OJB tandem is made of of ¾ plate and is completely boxed in. The tamdem is designed in a way that it will reduce weight on the front tires when these have to go over an obstacle.
The tandems have ADR 6”x6”axles with heavy bearings and 420mm drum brakes. The brakes can be hydraulic or air operated.

Steel Shaft

The tandem pivots on a 4”solid C1045 steel shaft. The shaft goes all the way the way to the middle of the trailer and can be greased through the centre.
The tandem has replaceable hardened steel bushings.

Open Front

The new model dump wagons have all around the top a rail made out of 3×4 HSS tubing which gives extra stiffness if the wagon gets loaded by a loader. The open front gives you all kinds of visibility into the box.
The lower edge on the front is to give the harvester a bigger target when you have to open up fields.

Long Tongue

The long tongue makes maneuvering easy and allows you to use a tractor with duals without hitting the box when you turn sharp.
All tongues are hydraulic operated. With this feature you can lower the front while opening up a field and you can unhook the dump wagon without using a jack.
