RORO vs Bin Type Skip Trailers: Which Do You Need?

A skip trailer is a purpose-built trailer designed to transport waste containers, skips, and bins between sites, recycling centres, and disposal facilities. Unlike a standard flatbed or tipping trailer, a skip trailer is engineered around the container it carries, with the loading and discharge mechanism matched to the container type and size.

Three main types of skip trailer serve the waste management and recycling industry: roll-on roll-off (RORO), bin type, and skeleton. Each addresses a different operational requirement. RORO trailers handle large containers using a hook-lift or cable system. Bin type trailers carry smaller integrated skips that tip to discharge. Skeleton trailers strip the chassis to a minimal frame, reducing tare weight to maximise payload within legal limits.

The right choice depends on several factors: the size and type of containers your operation uses, the loading method available at your sites, access constraints (yard dimensions, turning circles, overhead clearance), and the payload you need to achieve within gross vehicle weight limits. An operator running 40-cubic-yard containers for construction demolition waste has fundamentally different requirements from a domestic skip hire company shifting 8-yard skips around residential streets.

All three types fall within Chieftain's recycling and waste trailers range, and all are manufactured to the same standard at the Dungannon factory. The sections below break down each type so you can match the trailer to your operation.

A RORO skip trailer uses a hook-lift or cable system to roll containers on and off the trailer bed. The container sits on the ground at the collection point. The trailer reverses up to it, the hook engages a lifting bar on the container, and the hydraulic system pulls the container up and onto the trailer bed. At the destination, the process reverses: the container rolls off the back of the trailer and onto the ground. The driver never leaves the cab during loading or unloading.

RORO systems are compatible with CHEM-standard waste containers, the industry norm across the UK and Ireland. This standardisation means operators can use containers from different manufacturers interchangeably on the same trailer, which is a significant advantage for hire fleets and multi-site operations that source containers from various suppliers over time.

The typical RORO container ranges from 20 to 40 cubic yards. These are large, open-top steel containers used for construction and demolition waste, site clearance, industrial scrap, bulky recyclables, and high-volume general waste. The container size makes RORO trailers the standard choice for operations handling large volumes of material at each collection, where the efficiency of a single large container outweighs the flexibility of multiple smaller skips.

RORO skip trailers are best suited to construction and demolition contractors, recycling centres handling high-throughput material streams, site clearance operations, and industrial waste producers. The common thread is volume: if you are moving large containers between fixed sites with adequate access for a full-length RORO trailer, this is the most efficient method.

Chieftain's RORO skip trailers are available in 2-axle and 3-axle configurations to match different gross weight requirements. Both configurations are EU Type Approved and built with commercial axles, air suspension, and Wabco EBS braking. The 3-axle variant handles heavier containers and higher gross weights, while the 2-axle model offers a shorter wheelbase for tighter sites. Both use the same core specification: air suspension with raise/lower valve, load-sensing valves, spring brakes with automatic slack adjusters, and full LED lighting.

A bin type skip trailer carries an integrated skip or bin that tips to discharge its contents. Rather than rolling a separate container on and off the trailer, the bin is a permanent part of the trailer assembly. The skip lifts hydraulically at the front and tips rearward, emptying the load under gravity, then lowers back onto the trailer bed. It is a simpler mechanism than a RORO system, with fewer moving parts and a more compact overall footprint.

Bin type trailers work with smaller skip sizes, typically in the 6 to 12 cubic yard range. These are the skips most people picture when they think of skip hire: the open-top steel containers found on driveways, outside building sites, and in commercial yards across the country. The smaller container size makes bin type trailers the natural choice for domestic skip hire companies, smaller waste operations, and any application where the collection points are residential streets, tight commercial yards, or sites where a full-length RORO rig simply will not fit.

Access is often the deciding factor. A RORO trailer with a 40-yard container needs a straight approach, adequate length to reverse, and space to deposit the container. A bin type skip trailer operates in a fraction of the space. For skip hire operators whose bread and butter is delivering and collecting 8-yard skips from suburban driveways, the bin type trailer is the only practical option.

Chieftain's bin type skip trailers are built on a 2-axle chassis rated to 19 tonnes gross weight, with a 3.7-metre bed length. The specification reflects the same engineering standards as the rest of the range: commercial axles, EU Type Approval, air suspension with raise/lower valve, and Wabco EBS braking. The bed uses a chequered steel floor for grip and wear resistance, and six removable bolster posts allow different skip sizes to be secured on the same trailer. Custom-built options are available for operators with specific container dimensions or non-standard requirements.

The 19-tonne gross weight rating keeps the bin type trailer within the operating weight range of standard rigid trucks, which means operators do not need specialist tractor units. This makes it a practical entry point for smaller waste companies scaling up their fleet, or established operators adding a dedicated skip hire capability alongside their existing RORO operation.

A skeleton skip trailer (sometimes called a skelly) takes a different approach to the same problem. Instead of integrating a bin or providing a full-bed RORO mechanism, the skeleton trailer provides a minimal skeletal frame that supports the container while stripping away all unnecessary bodywork. The result is the lowest possible tare weight, which directly translates to the highest possible payload within legal gross vehicle weight limits.

The maths is straightforward. If your gross vehicle weight limit is fixed by regulation, every kilogram of trailer weight is a kilogram you cannot carry as payload. A skeleton trailer might save 500 to 800 kilograms of tare weight compared to a fully bodied alternative. For an operator making multiple trips per day, five or six days a week, that additional payload per trip accumulates into a significant tonnage advantage over the course of a year.

Skeleton skip trailers are best suited to operators who work with standard container sizes, where the container itself provides the structural containment for the load and the trailer only needs to support it during transport. They are the preferred choice for weight-sensitive operations where maximising payload is the primary commercial objective, particularly when hauling dense materials such as soil, rubble, scrap metal, or wet waste that reach the weight limit well before filling the container volume.

The trade-off is versatility. A skeleton trailer is optimised for a specific container type and size range. It will not handle the variety of container configurations that a RORO trailer can accommodate, nor does it offer the integrated tipping capability of a bin type. It is a specialist tool for operators who know exactly what they are carrying and want to carry as much of it as legally possible on every trip.

Chieftain's skeleton skip trailers are designed to reduce tare weight without compromising structural integrity. The chassis uses high-strength steel in a skeletal configuration that distributes container loads through the axles and suspension, maintaining the durability expected of a Chieftain trailer while achieving the weight savings that justify the skeletal design.

All three skip trailer types, RORO, bin type, and skeleton, are manufactured at Chieftain's factory in Dungannon, where every trailer has been built since 1969. The entire recycling and waste trailers range carries EU Type Approval, ensuring compliance with current road-going regulations across the UK, Ireland, and Europe.

Across the range, the core specification reflects Chieftain's approach to commercial trailer engineering. Commercial axles with air suspension and raise/lower valve provide ride quality and load protection on the road, with the ability to adjust ride height for loading and coupling. Wabco EBS braking with ISO 7638 sockets delivers electronically controlled, load-sensing braking with ABS. Spring brakes with automatic slack adjusters handle parking and emergency braking without manual adjustment. Load-sensing valves modulate braking force based on the trailer's loaded state. Full 24V ISO lighting with LED clusters ensures visibility and compliance.

The choice between the three types comes down to your operation. If you run large CHEM-standard containers for construction, demolition, or industrial waste, the RORO is your trailer. If you run a skip hire operation placing and collecting smaller skips on domestic and commercial sites, the bin type is purpose-built for that work. If payload is your primary constraint and you run standard containers of dense material, the skeleton chassis gives you the weight advantage.

Many waste management companies run a mixed fleet, combining RORO trailers for large-container work with bin type trailers for domestic skip hire. This is a practical approach that matches the right trailer to each job rather than forcing a single type to cover every scenario. Because all three types share the same braking, suspension, and electrical architecture, parts commonality across a mixed fleet is high, simplifying maintenance and reducing spare parts inventory.

Every skip trailer Chieftain produces is built to order, which means bespoke specifications are available. Bed length, axle configuration, container securing arrangements, hydraulic specifications, and finish can all be tailored to match your containers, your trucks, and your operating environment.
