The page most suppliers hope you never ask about

Downtime is where your money leaks, and an unplanned stop costs far more than the part that caused it. So here are the numbers, written down, with the parts we do not control stated plainly rather than buried.

The four commitments, in numbers

SPARE PARTS

Within two months, worst case

Wear and spare parts are supplied within two months at the very worst, and typically far sooner for models in current production. Mantles, concaves, jaw plates, blow bars, screen media and bearings are the items we hold or make to the same drawings as the machine.

REMOTE

Response within one working day

Photos, video or a video call. Most mechanical and electrical problems are diagnosed remotely, often the same day — and parts are identified before they fail rather than after. Remote support is included, not charged.

ON-SITE

Engineers within 10 days

For installation, commissioning and major overhauls, our engineers travel to your site — attendance within 10 days of the requirement being agreed, for clients in our export markets. For remote inland sites, tell us the access route at order stage.

WARRANTY

Written on the contract

Warranty period, coverage and exclusions stated in the contract in the same words as we publish here. No asterisks, and no discovery at claim time.

What we keep, and what we do not

We make the machines, so the parts that come off our own drawings are the parts we can supply fastest: frames, shafts, eccentric assemblies, bowl and adjustment components, and the wear parts for our own crusher models. Those are available by model number or, where a machine's history is incomplete, by drawing.

Some components are bought-in items — motors, gearboxes, bearings, electrical components, hydraulic pumps and seals. These come from recognised suppliers with their own distribution networks, which is usually good news for availability; but we do not pretend to control a bearing manufacturer's global stock. What we do is tell you at order stage which items on your machine are bought-in, so that you can plan your spares holding against the right lead times instead of assuming everything comes at the same speed.

We will tell you which category each critical item on your machine falls into, in writing, at order stage. That list is what your store should be built from.

The first-year wear schedule

Every line and major machine ships with a recommended first-year wear-parts forecast based on your material and duty. It exists so that a planned stop replaces a part, rather than an unplanned stop discovering one.

  • Wear items listed by machine, with expected service intervals based on your rock type and duty cycle.
  • A recommended parts holding for your store — what to keep, what to order on lead time, what to source locally.
  • Inspection points and frequencies, so wear is measured rather than guessed from the sound of the machine.
  • Liner profiles and settings recorded at commissioning, so a capacity drift can be traced to the actual cause.
What we ask of you. Follow the lubrication schedule and record the oil analysis. Replace wear parts on the schedule rather than on failure. Keep the site's electrical supply within the specified tolerance. The long-running references on our projects page — including a Nigerian client at twelve years and counting — are clients who did all three.

Warranty and what is excluded

The warranty period, coverage and exclusions are agreed at order and stated in the contract using the same wording published here. The honest version of a warranty page says what is not covered, so:

Covered: manufacturing defects in components we manufacture
Covered: capacity and product-size compliance to the agreed configuration, verified at acceptance
Covered: replacement of defective manufactured parts within the warranty period
Not covered: normal wear of consumable parts — liners, jaw plates, screen media
Not covered: damage from uncrushable material, overloading beyond the specified duty, or operation outside the manual
Not covered: failures caused by power supply outside the specified tolerance, or by unauthorised modification
Not covered: consequential loss, including production loss, beyond the value of the parts replaced

Common questions

What is the realistic lead time for a mantle or set of jaw plates?

Typically well inside two months, and often substantially faster for models in current production — but the honest answer depends on the specific part and the shipping leg. Send us the model and the part and we will give you a dated answer rather than a general one. This is exactly the question we would want answered before choosing a supplier.

Do you supply parts for machines you did not manufacture?

Sometimes, where the part is a standard wear item or where we can work from a drawing. Send us the drawing or a photograph with dimensions and we will tell you honestly whether we can make it. If we cannot, we will say so rather than take the order and deliver something that does not fit.

How does remote diagnosis work in practice?

Send photographs or a video of the problem, or ask for a video call. In most mechanical and electrical cases we can identify the cause and the required part the same day. For hydraulic and control issues a video call with someone standing at the panel is usually faster than a site visit — which is why we try remote first rather than billing you for a flight.

What happens if a part fails inside the warranty period?

We replace the defective part. Where the failure is site-dependent — power quality, feed conditions, operation outside the manual — we will say so and explain why, rather than hide behind the clause. Either way you get a written explanation, which is useful to your own management and to us: recurring failures of the same part are a design signal, not just a service event.

Need a part, or a wear-cost estimate?

Send the machine model and the part. You get a dated answer, not a general one. For a full wear-cost forecast, send your rock type and duty cycle and we will model the first year.
