Longwall Products

Jet’s long term history in underground mining means we have a great understanding of what clients need when it comes to quality, performance and safety. Our longwall product range consists of a mixture of innovative original products and aftermarket OEM products.

Original design products include Bretby installation tools, which prevent serious injuries to operators’ hands and our spray nozzle strainer / adaptors which prevent blockage of spray nozzles, thereby reducing downtime and maintenance requirements.

Our aftermarket OEM products are high quality replicas of OEM parts. In many cases the Jet parts feature design improvements to make them longer lasting than genuine components.

We take pride in producing consistently quality components with high quality welding and consistent weld sizes. We supply parts ready assembled with all of the pins, etc. required for installation. We also make sure the products are well presented when dispatched, so they look good when they arrive on site.

When it comes to aftermarket OEM products at Jet, it’s all about “The right parts at the right price”

Flippers

Our flippers are manufactured to Jet's high standards, and supplied complete with all linkages, pins, and fasteners required for installation.

Side Seals

We use semi-automated weld processes to efficiently manufacture side seals to the highest standards of quality. Our side seals are supplied complete with all of the pins and fasteners required for installation.

PM4 Brackets

Whether you require replicas of your current brackets, or whether you require design improvements, we can manufacture PM4 brackets that match your exact requirements.

Centre Walkways

Our centre walkways are designed to prevent injuries and save money.  Surfaced with 316 stainless steel perforated plate, they provide 360° slip resistance, with the maximum service life.

Pontoon Covers / Tread Plates

In addition to providing an even, non-slip surface over the entire pontoon, our pontoon covers have innovative features that prevent the prevent the polyurethane from peeling, and that prevent the front corners of the covers from lifting.

These factors work together to ensure that our pontoon covers provide a safer working environment for longwall operators, while also having a longer service life.

Leg Cylinder Valve Covers

Our leg cylinder valve covers are a great example of our "right parts at the right price" philosophy.  Our covers are jig manufactured to ensure they fit onto your roof supports like an original component, but our low overheads allows us to offer you significant savings.

Shearer Stops

We can accurately replicate your existing shearer stops to provide you with spares.  Or if you need to adjust the travel limits of your shearer, our experienced personnel site measure, design and manufacture new shearer stops that meet your exact requirements.

Steel Sets (Beam Sets)

When a major weighting event happens on a longwall face, a swift reaction is critical to minimise the extent and cost of downtime that inevitably occurs.  We have a proud history of supporting collieries as they work through the difficult process of recovering the face.

Within minutes of receiving a phone call to supply steel sets, we have our design team working on drafting the required components.  Within the first hour, we have materials en route to our workshop to commence manufacture.  Within 24 hours, we have landed an initial batch of steel sets, installation drawings and a certification report on site.  We then devote our entire production workforce to manufacturing the remaining steel sets, on day shift and night, for as long as it takes to get the job done.

When the pressure is on, you can rely on Jet.

Staple Remover (Polly)

Made from BIS 80 plate for improved strength and durability, we have staple removers available in a range of sizes.

Canopy Spray Brackets

Our canopy spray brackets allow sprays to be retrofitted to shield canopies on the face.  The innovative design allows installation to be carried out with no requirement for welding or drilling.  What's more, protrusion of the brackets and sprays from the canopies is minimised, reducing the risk of them being impacted by the shearer.

Spray Nozzle Strainer Adaptors

Our strainer adaptors are designed to be installed between existing spray nozzles and manifolds.  The stainless steel screens filter the water and prevent the sprays from blocking, thereby minimising downtime and maintenance requirements. The adaptor bodies are machined from 316 stainless steel to prevent corrosion and maximise service life.

We have a range of sizes available to suit a wide variety of spray nozzle and manifold designs.
