Features

Tapered body design

reduces excess material buildup from loading.  – The upper hopper opening is 102″ wide (97” inside width) which tapers down at an 11ᴼ angle. This creates two benefits: It allows material to flow easier, reducing material hang-up and promotes reliable discharge. Additionally, it promotes a narrower span at the lower hopper (81″ wide at the frame) which reduces material hang-up from load spillage.

Internal corner bracing

reduces excess material buildup from loading.  – The upper hopper opening is 102″ wide (97” inside width) which tapers down at an 11ᴼ angle. This creates two benefits: It allows material to flow easier, reducing material hang-up and promotes reliable discharge. Additionally, it promotes a narrower span at the lower hopper (81″ wide at the frame) which reduces material hang-up from load spillage.

Back welding

The Lower Hopper is not welded to the bottom of the frame, rather it is back-welded above the frame edge. This allows for greater flexibility reducing stress cracking and damage. It is also superior cosmetically in that the solid weld prevents rust streaks from marring the finish of the lower hopper.

22 cubic yards capacity

Our semi-trailer hopper boasts a full 22 cubic yards capacity, level full. With 8″ Side boards that increases to 25 cubic yards and 26.5 cubic yard capacity with our 12″ aluminum side boards. Calculated water level to the top of the boards

Side boards

Side Boards are mounted to be flush with outside of the top rail preventing material build-up, eliminating fugitive material from littering the road.

Short Push Block

Our short Push Block has several important features. Among them – it is removable, it can be easily repaired or replaced. – It is durable enough to be pushed but significantly lighter than larger options. – The design allows for a pup to be towed without requiring the push block to be removed.

Windrow Deflector

Our Bolt-On Windrow Deflector is repairable and replaceable. Because the windrow deflector is one of the most abused pieces of equipment on the trailer we have made it easy to remove and repair. Replacements are also available and in stock.

Frame integrity

Maintaining trailer frame integrity is vital. Our trailers use an 80,000 psi tubular steel frame designed to reduce stress on critical areas through frame padding and controlled heating during construction, preventing direct heat exposure and stress concentration, thus avoiding breakage points.

Compact design

The compact design allows the Ranco bottom dump trailer to be classified as a rear tire vehicle and not requiring the rear impact protection as per (§ 571.223 – 224).
If your circumstance or safety program requires rear impact protection, we offer a larger push block with the full ICC bumper.

Quality gates

We have gone to great lengths to create the best gates in the industry. Through extensive engineering and testing we’ve created a gate system that does not stick shut while under a wet or sticky load. Nor do our gates get sprung or damaged from normal wear and tear.

Formed gussets

Our formed gussets also allow the disbursement of stress. By avoiding sharp reliefs or corners the rounded gussets allow for flexibility and the reduction of concentrated stress areas.

AR250 steel

Our gate face is made with abrasion resistant AR250 steel which is more durable and provides a longer life for our two axle & three axle trailers (the gate face can be upgraded to AR400).

Fenders

The fenders and rear mud flap bracket offer greater functionality by not being welded directly to the frame. If the trailer is hit from behind or should a dozer blade slip off the push block and hit the back of the trailer. The fenders and mud flap bracket will shear off reducing the stress on the frame. If the fenders were welded solid all of the force would be pushed into the frame.

Sealed gates

Our sealed gates prevent material spillage, reducing liability from broken windshields, errant debris dropping from the trailer. We control this issue with our replaceable bolt-on lower hopper extensions and gate side seals.

Oversized gate bearings

Our heavy duty oversized gate bearing on these Ranco Bottom/Belly Dump Trailers provides longer life and supports greater gate torque. This is one of the reasons why our gates do not require alignment guides.

Landing legs

Our landing legs are not attached to the gates so when sitting the gates are not required to support the weight of the trailer.

Quick release valves

installed on both the inflow and exhaust ports of the cylinder, because we believe it is just as important to pinch off the flow of material as it is to open the gates.

Gate safety

Our gates are high off the ground offering a little more leeway from high centering at lower speeds. Additionally, this offers reduced windrow drag extending the life of the gate and reducing gate yaw.
