The Custom Body Dump Trailers are the lightest bulk commodity trailers in the range, fully custom-made to suit your business needs.
Since 2011 GLT has been building B-Double bottom dump trailers as light as 9.7 tonnes. This means, you could have a paid load of over 44 tonnes on GML with a light weight truck.
Designed and made in Australia, GLT bottom dump trailers feature the highest quality parts and materials.

GLT custom extruded planks. These are ideal for maximum height bodies as they reduce the amount of side wall bulge. Using plank sides gives us the ability to create sides up to 4.3mtrs.

The GLT lower curve is an exclusive extrusion. The side sheet and floor sheet slot into the extrusion before they are hand welded into place.

GLT can remove the lower curve and press the side sheet to meet the floor sheet. This will reduce the tare weight by around 70kg. It also increases the strength of the tubs making it an ideal option for carrying liquid based goods.

Lower sections are formed from 10mm plate which is then joined to 8mm plate midway up the wall. Mill finish plate is used which can be left raw or painted.

This option is ideal for carrying liquid based products. The front sheet is specially rolled before being welded into the place. As liquids move forward when decelerating, the shape of the front sheet reduces the liquid’s impact. We recommend a thickness of 6mm to add stiffness to the front sheet which reduces fatigue

This is our standard front sheet which is 5mm thick with a polished finish. Other thicknesses and finishes are available

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

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

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

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

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

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

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

This air-operated tarp solution 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.

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

By far our most po[pular option. The tarps rolls up neat and tidy out of the way when loading. When unrolled, the tarp offers a high lvel 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.

If you want the most water proof tarp option, tick this option. Tarps come standard with 300mm ling 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. Thisgives you a bit of extra room to roll over the heaped loads while still getting a tight seal along the side of the tub.

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

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

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

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

GLT 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 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.

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

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

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 comparted to paint. Select from a large range of colour options.

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.

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

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

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 an 8mm thick aluminum bracket, making them very strong and stable.

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

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.

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

Another well-known EBS unit popular with our clients. This unit offers stability control and EBS braking. Knorr Bremse offer excellent technical aftersales support.

If safety is high on your list when operating, then you need to consider the Wabco EBS system. This electrically0controlled braking system helps to reduce the risk of serious accidents.
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.
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.
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
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.
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 the flanges are sanded and polished to reduce the chances of cracking and to help paint adhere to the steel
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.
