The GLT Slider is a versatile unit. It can be used as a lead trailer in a B-Double configuration or with a flick of a switch the axle group can be unlocked and slid forward. Being locked in this forward position it can be used in a road train configuration when a Ringfeder and second king pin is installed.

A standard tri axle spec GLT Slider 30’ grain spec will tip the scales at 6.8 tonnes without a Ringfeder. In a road train spec with Ringfeder and double king pins that weight will increase to 7.2 tonnes.

Our Sliders can be designed to fit into PBS A-Double axle spacing’s by utilising secondary lock positions.

Sliders are available in tandem, tri or quad axle configurations. We have a large range of options to customise your new Slider. See our options listed below.

All GLT aluminium bodies are fabricated from European sourced marine grade aluminium plate. Floor and wall sheet thicknesses can be customised to suit the application.

Each body is built on our exclusive extruded aluminium floor beams. The beams are specifically cambered to suit the body length. The process of welding the floor sheet to the beams and cambering the beams all happens simultaneously.
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.
All trailers with a king pin position less then 900mm come standard with a Jost body lock. GLT bodies are designed to have the hoist feet mounted directly above the king pin to increase strength and stability while tipping. Bodies with upright hoists need the body lock to help hold the body in position while traveling.
Fronius machines are used to create superior welds on all aluminium sections.

Body type options include

Straight Body – This standard body type is a strong, cost effective and a light weight option. Choose from two body widths: Narrow – 2,330mm or Wide (standard) – 2,480mm.

Side wall options include

Plate – 4mm to 12mm thickness.Choose from either mill finish, mill bright (polished), painted or vinyl.

Standard Lower Curve – 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.

Pressed Sides – 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.

Plank – GLT custom extruded planks. These are ideal for maximum height bodies as they reduce the amount of side wall bulge. This option will increase the trailer tare weight by around 80kg depending on length and height.

Front sheet options include

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

Rounded Front Sheet – 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.


GLT Sliders are a modular design which are almost entirely fabricated from 700 grade mechanical steel. All our skid plates are fabricated from quenched and tempered steel.

Each chassis is 3D modelled and laser cut. Our steel fabrication team are highly skilled qualified tradesmen. Miller digital pulse welders are used to lay a clean weld. All edges on flanges are sanded and polished to reduce the chances of cracking and to help the paint adhere to the steel.

The top half of the Slider comes in 3 sizes to suit a 28’, 30’and 31’. The lower half is built for either an 8’1’’ or 9’1’’ axle spread. Custom-hardened nylon wear pads are installed at contact points between the 2 halves to allow a smooth slide action. The top half and low half are married up and slid multiple times before they are sent to paint.

Our Sliders have the option to be built with a double king pin and Ringfeder. This will enable the trailer to be used in different multi vehicle combinations. The Slider locking pins are set up with a cabin controlled air switch as standard.

Our pivots use a superior, thorough design, which greatly increases the strength of the pivot area. A 50mm pivot pin is slotted through a welded connection, making it exceptionally strong.


GLT trailers are designed to handle the harsh Australian conditions. The correct suspension and axle selection is one of the most important factors in the trailers’ ability to survive our unique roads.

GLT chassis are optimised for Hendrickson INTRAAX air bag suspension and Hendrickson axles. Other brands such as BPW, SAF and K-Hitch can also be equipped if requested. GLT is an authorised Hendrickson dealer which allows us to offer greater after-sales support.

Air bag suspension offers better ride quality, low tare weight and simplified ways of reading load weights. The prefered 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.

Mechanical spring suspension can be fitted to most GLT trailers. K-Hitch KHDO/KHU and FW88 are our preferred suspension models.
