What Are Self-Propelled Modular Transporters And How Do We Use Them?
At JB Rawcliffe & Sons Ltd, we’re experts in transporting heavy cargo for several sectors and perform tasks with the use of a wide range of heavy equipment that possess extreme load capacity.
The heavy loads we deal with are transported around the UK with heavy haulage trucks and a variety of specialist equipment. One such piece of equipment is a self-propelled modular transporter (SPMT).
What is a self-propelled modular transporter?
A self-propelled modular transporter is a platform vehicle that features a large number of wheels and consists of different modules with an axle line count of four, five, six or eight.
Each module has its own engine and steering control system. A self-propelled modular transporter is perfect for transporting massive objects like oil refining sections, motors, large sections of bridges, and other items that are too big for a truck.
How do we use self-propelled modular transporters?
At JB Rawcliffe & Sons Ltd, we’re able to call upon 28 lines of SPMTs, that offer a capacity of over 1000 tonnes, for the movement of even the heaviest cargo.
Our SPMTs are ideally suited for a variety of trailer lengths and can be adapted to multiple widths to transport wide loads. This depends on the load capacity, dimensions and the scale of the project and, as a result, these adjustments make SPMTs perfect for operation in severe conditions.
Some of our SPMTs also feature a reduced height and compact design which makes them easier to operate in small spaces.
Arguably the best thing about SPMTs is that they can be coupled side to side and end to end, which enables us to carry even more cargo.
We can also operate remote units as single transporters. These mechanical steering trailers are controlled by electro-hydraulic motors and offer exceptional control, even in the tightest spaces.
Features of SPMTs
SPMTs have the highest load capacities in the world and can transport huge cargo. For this reason, they have transformed the construction of bridges. There are several other interesting features that SPMTs boast, such as:
- SPMTs can drive automatically without the tractor’s traction
- They can be customised in length and width to fit transportation requirements
- Each axle line is controlled independently
- Engineers control SPMTs via a computer or handheld device, while some have a driver cabin
What’s the difference between an SPMT and a modular trailer?
A modular trailer is a special platform trailer that features swing axles, steerable axles, and hydraulic suspensions. They’re used to transport oversized loads that are difficult to disassemble, but they are different to self-propelled modular transporters.
An SPMT is a platform vehicle that consists of wheels that drive and turn independently. It’s used on-site to transport huge, bulky items.
The main difference between an SPMT and a modular trailer is that the former is self-contained and the latter requires a tractor unit.

What Is A Low Loader Trailer?
When it comes to transporting heavy loads, you need a special kind of trailer – one that’s strong enough to carry the weight of your machinery, with the stability and power to get it from A to B on time.
Luckily, as a leading transport company in the UK, we have an extensive fleet of haulage vehicles at our disposal, here at JB Rawcliffe – including low loader trailers.
What is a low loader?
A low loader is a type of flatbed trailer, specifically designed to carry industrial goods and heavy pieces of equipment safely and efficiently.
It has two drops in deck height that allow it to be much lower to the ground than other trailers.
This not only makes it easier to load equipment (including taller machine and wider objects), but it also lowers the centre of gravity for the goods in transit, ensuring safe transportation from start to finish.
A low loader trailer attaches directly to a prime mover, offering a robust transport solution for even the largest of machines.
Why should you consider a low loader trailer for your haulage?
Though they are often a staple for construction projects, low loaders are widely used among different industries – thanks to their functionality and cost-efficiency for hauling major resources.
Low loaders have adjustable height settings, which makes life easier for you when loading large and heavy cargo.
They can legally bear more weight than others and, as a result of their low height, they are perfect for transporting abnormal loads that cannot be split into separate deliveries.
Something else worth noting about these vehicles within our fleet is that they are incredibly flexible. They are straightforward to manoeuvre around sites and the trailer itself can be extended or lowered to allow for taller goods.
Due to their height, they are usually less affected by strong winds, too – ensuring maximum safety and security for the goods being transported.
As the loading process is much easier, the need for manual labour (and the risk of workers injuring themselves) is significantly reduced.
How do you hire a low loader?
Hiring a low loader for heavy haulage couldn’t be simpler than it is, here at JB Rawcliffe.
Our experts have vast experience in the haulage industry and have had the privilege of working with clients from various sectors for more than 45 years.
Before we determine the most suitable haulage vehicle for your project, we’ll need to know a little more about the goods you need to transport and the driving conditions.
Armed with a basic understanding of the task at hand, we will advise you on the best low loader for the job – ensuring maximum safety for the load being delivered and potentially shortening lead times.

What Are Strand Jack Systems And How Are They Used?
A strand jack is a type of linear winch that’s used to pull heavy loads from above – offering a compact and precise solution for heavy lifting and lowering operations.
Unlike regular jacks that push the load up, strand jacks have a bundle of steel cables (otherwise known as strands) that are guided through a hydraulic cylinder and pulled up.
These systems have two clamps: one at the bottom which is fixed, and another at the top which is connected to the cylinder and moves up and down.
Both clamps have wedges that grip the strand. The lifting or lowering motion is achieved by the cylinder extending and retracting while the wedges lock onto each strand in turn.
In this blog, we’ll take a closer look at strand jacks and their uses – including the different industries they can be employed and the benefits they bring.
What are strand jacks used for?
Strand jack systems are widely used in heavy construction and engineering industries – particularly for bridges, ports and large-scale plant maintenance projects.
The hydraulic cylinders and strands allow heavy loads to be lifted to the required height, but objects and structures can also be pulled (skidded) into a certain position.
Although a strand jack can be used to lift, handle and lower heavy machinery and equipment within construction and engineering, they can also be used in the oil and gas industry.
Multiple strand jacks can be operated simultaneously by hydraulic controllers at oil rigs, and they can be used in tandem to lift heavy offshore platforms from or onto barges.
Why are strand jack systems used?
Strand jacks offer several advantages that make them useful for the aforementioned industries – one of their main ones being that they have a small footprint. This makes them ideal if there is a lack of space on the construction or assembly site for a conventional crane.
Despite their compact size, strand jack systems can still lift and lower machinery and equipment with excellent precision – ensuring they are transferred safely and efficiently.
These systems frequently provide a viable alternative for lifting loads that are not suitable to be jacked from beneath. They offer an economic and controlled solution for lifting, turning, transferring and lowering cumbersome loads.
As opposed to cranes that normally use a single-strand hoist with pulleys to lift the load, strand jack systems use multiple strands to lift the load – making it much safer.
What’s more, strand jacks can be conveniently operated by a single operator using a computer or controller in a central location. And they operate at various speeds, helping to enhance productivity and efficiency on site.

What Are The Benefits Of Tracked HIAB Crane Hire?
Do you need to lift and transport goods in remote locations?
Might we suggest tracked HIAB crane hire?
A tracked HIAB is equipped with a hydraulic lorry loader and loading bed, which makes it perfect for lifting cargo in rough terrain. This specialist HIAB makes light work of the most challenging lifting operations – reaching heights that other vehicles simply cannot.
Below, we look at some of the ways you can benefit from hiring a tracked HIAB crane and why you should hire one from JB Rawcliffe & Sons.
· A tracked HIAB crane can lift and move loads with ease
With its powerful hydraulic crane, a tracked HIAB is an incredibly hardworking machine that can be used to effortlessly haul goods of all shapes and sizes in difficult-to-reach areas.
The control system allows for precise positioning and operation – even in adverse terrain conditions – ensuring maximum safety and efficiency on-site.
· Tracked HIAB crane hire is convenient
Combining the ability to load and unload heavy goods, and transport them to their final destination, a tracked machine with a mounted crane offers a cost-effective alternative to a standard crane.
Facilitating rapid set-up and excellent manoeuvrability – and with no prep work required on-site – lifting operations can be started (and completed) in less time, too.
· Tracked HIABs enhance safety
Operating any sort of machinery when the ground is soft and wet underfoot can be risky – both for the operators and the goods in transit. But thanks to their brilliant stability and traction, tracked machines mounted with cranes can navigate even the harshest of conditions.
For example, a tracked Morooka-type HIAB like the ones we provide at JB Rawcliffe can carefully transport and lift loads to otherwise inaccessible locations. And as part of our tracked HIAB crane hire service, we’ll execute the logistics – making sure that the machinery is loaded and offloaded correctly, and that deliveries run as smoothly as possible.
· Tracked HIAB crane hire can be tailored to your requirements
Do you need to lift and move construction materials, heavy machinery or other cumbersome items?
The tracked HIAB is designed to handle various weights and sizes – making it suitable for a wide range of industries. Including agriculture, construction, energy and telecommunications, to name just a few.
