Our lightest bulk commodity trailers. Since 2011 GLT has been building B-Double bottom dump trailers as light as 9.7 tonnes. If you do the math, you could have a paid load of over 44 tonnes on GML with a light weight truck.

Product is discharged through multiple chutes at the base of the trailer. Depending on the type of combination you are after, compartment locations and discharge points can be moved to achieve correct axle weights.

All GLT bottom dump trailers are chassis-less design. The skid plate and suspension modules are bolted onto the body which decreases the tare weight of the trailer. Chutes can be optioned with manual wind open or electronic remote controls.

All nuts, bolts and washers are stainless steel. All GLT trailers are laser wheel aligned prior to delivery. GLT chassis tippers are available in tandem, tri or quad axle configurations. We have a large range of options to customise your new chassis tipper. See below for some of our most popular options.

GLT bottom dump bodies are exclusively made from European sourced marine grade aluminium plate. We recommend thicknesses of 6mm for the floor and 5mm for the walls.

Our construction methods allow us to dramatically decrease the tare weight by having a chassis-less design. The body is engineered to have the skid plate and suspension modules bolted to the main aluminium assembly.

Compartments are custom designed to achieve your desired cubic capacity and axle weights. The floor angle is also customised to suit the angle of repose for your product.

Top coamings are also an exclusive aluminium extrusion. These specialised extrusions increase the tub body strength while maintaining exceptional tare weight. All top coamings are either huck riveted or bolted with stainless steel bolts. This method of construction allows the coaming to flex and reduces the risk of cracking.

Fronius machines are used to create superior welds on all aluminium sections.

Side Wall Options Include

To gain maximum tare weight savings on B trailers, aluminium suspension hangers can be optioned. These aluminium hangers are welded directly onto the main beams which eliminate all steel work from the rear of the trailer.

All edges on flanges are sanded and polished to reduce the chances of cracking and to help paint adhere to the steel.

GLT’s range of bottom dump trailers are optimised for Hendrickson air bag suspension. Other suspension brand can be selected with a tare weight increase.

Air bag suspension offers better ride quality, low tare weight and simplified ways of reading load weights. The preferred brands which we supply have passed our field testing protocol and have excellent after sales support. All trailers with air bag suspension are equipped with ball valve taps to isolate individual bags. These taps will allow you to shut off an air bag if it has an issue.

Customised to suit any application
Trailer Options

Manual Chutes

GLT bottom dump units come standard with manually operated chutes. Our winding mechanism is simple to use and has a light action.

Razor Chutes

This Razor option gives you the ability to control the opening and closing of the chutes via remote control.

Rollover with Pelmets

By far our most popular option. The tarp rolls up neat and tidy out of the way when loading. When unrolled, the tarp offers a high level of cover to protect your load.  Compared to the QLD style tarp, the roll over is easier for the operator to use, reducing OH&S risks. Side drop is 300mm standard and can be increased to 600mm. A full range of colours available. Razor electronic tarp upgrade available on this tarp.

QLD Style

If you want the most water proof tarp option, tick this option. Tarps come standard with 300mm long flaps front and rear which are pull down tight to seal the front and rear of the tub. The side drop is standard at 600mm. This gives you a bit of extra room to roll over the heaped loads while still getting a tight seal along the side of the tub. A full range of colours are available.

Retractable with flap ends

These tarps retract forward to allow loading. The rear part of the tarp has a flap end which is pulled down tight to seal the rear of the trailer once loaded. The tarp supports can range from 200mm to 350mm high.  Retractable tarps are not waterproof and leaking can occur.  A full range of colours are available. 

Retractable with plate ends

These tarps retract forward to allow loading. The rear part of the tarp has a sliding aluminium pelmet.  The tarp supports can range from 200mm to 350mm high.  Retractable tarps are not waterproof and leaking can occur.  A full range of colours are available.  

Hooded

Custom designed in-house by our boffins, this system uses hydraulic cylinders to open and close the hoods. The structure is made from aluminium to reduce tare weight. This system has a fast opening time at 10 seconds flat. A full range of colours are available.

Tarp Controls - Manual

Manual tarps come with stainless steel handles.  Sliders and rollbacks come equipped standard with telescopic handles. All other trailers are equipped with fixed length handles as standard with telescopic as an option. 

Tarp Controls - Razor Electrical

Let technology do the hard work for you. Razor is available on the retractable and roll over tarps with pelmets. This system is supplied with a Razor remote control. 

Tarp Material - PVC

This material is water-tight and comes in a range of colours. Ideal choice for operators wanting maximum protection from the elements.

Tarp Material - Mesh

Lightweight and permeable, this material comes in a range of colours.

Tarp Support - Flexbow

Strong and flexible.  These supports are made from composite material which bend and flex back into place.  We bolt the bows into place so they always flex back at the correct angle. 

Tarp Support - Rolled Aluminium RHS

This is a popular option for operators wanting a tough alternative to Flexbows. These supports can be spaced at custom intervals. 

Tarp Support - Air Flip Over Bar

This air-operated tarp support can be operated from either the trailer via a push/pull switch or truck cabin controlled switches. The bar and centre pelmet is designed to be contamination free.

Tarp Support - Steel Bows

These bows are mounted into our standard flex bow pockets and bolted. These supports can be spaced at custom intervals.

Custom Spacing

Our standard light spacing interval is 1300-1500mm. If you want more light bling then we can go as close as 300mm between lights. We also offer lights at the top of the side sheets at matching intervals.

Work Lights

Work lights can be fitted to the tailgates, wings on RediTips and within the tubs either up the front near the hoist well or near the rear door.

Top of Tailgate Lights

Choose from either 9, 10, 12 or 14 lights at the top of the tailgate.

Mill Finish

This is our base level finish.  It's a natural granular finish and holds up pretty well to staining.

Mill Bright Polished Finish

Want to maintain a high level of upper body fitness?  This super shiny sheet will require lots of polishing to maintain the mirror finish.  Is it worth it? Yes, these sheets look amazing!

Painted

Choose from a large range of colours to personalise your trailers. We use only premium quality paints.

Plank Side Powder Coated

Our planks come standard with white powder coating. If you require different colouring, please allow a 6 week turnaround.

Vinyl

A popular option. The vinyl is applied in 1400mm wide drops with a slight overlap. Each drop can be replaced if they get damaged, making it less expensive to maintain compared to paint.

Signwriting

Give your company an advertising boost. We have contractors who specialise in truck and trailer signwriting. They will work closely with you to custom design your signage layout.

Plastic Radius Guards

Choose from a range of colours.  Our standard brand is Maxus with other brands such as Truckmate.  Our radius guards are mounted to the chassis by a 8mm thick alumimium bracket, making them very strong and stable. 

Chrome Dress Strips

Dress up your radius guards with chrome dress strips.  These look great and finish off the guard area nicely. 

Stainless Steel Radius Guards

If you want the bling look then stainless steel radius guards are the go.  We recommend the ribbed type as they hold up to rougher conditions better.

Splash Guards

The simple clean way to finish off the guards on a B trailer. Horse hair is added to reduce water spray.

Conveyor Guards

Built to handle the harsh Australian environment. Rubber can range in thickness and colour.
