Cables for Stackers, Reclaimers, Grabs and Bulk Handling Machines
Bulk handling machines combine the worst of every duty: long travel on a reeling drum, constant abrasion from dust and aggregate, wind loading on an exposed boom, and often continuous operation rather than intermittent cycles. The cable is the component that fails first on a stacker or reclaimer because it is the only part that flexes on every stroke.
Specification for this sector tends to focus on three things — tensile reinforcement for the suspended length, a jacket compound that resists abrasion rather than just oil, and a core construction that survives winding in layers on a large drum.
What decides the cable in this application
Four factors do most of the work. Getting these right narrows the choice to a small number of constructions, and each one appears in the specification table of the cable type you select.
Abrasion, not oil, is the dominant wear mechanism
Coal, ore, aggregate and dust abrade the jacket continuously across a large contact area. Wear-resistant compounds and in some cases reinforced outer layers are what determine jacket life here.
Long booms mean long, heavy suspended cable
A boom-mounted cable on a stacker can hang over a hundred metres. Tensile reinforcement carries that weight and keeps the conductors out of the load path.
Wind loading on an exposed boom
On open stockyards, the cable is exposed to wind across the whole boom length. That adds lateral load and oscillation to a run that is already under tension.
Continuous duty leaves no time for a failure
Stackers and reclaimers often run continuously rather than in shifts, so a cable failure stops the material flow immediately. D/d ratio and cycle life rating matter more here than on intermittent machines.

What we need to quote accurately
Send these six items and we can confirm a construction and price without a follow-up round. Both the contact page and every product page carry a form that accepts them, and you can attach a drawing or specification sheet directly.
- 1 Machine type Bucket wheel stacker, reclaimer, grab crane, LHD, waste handling
- 2 Drum or festoon details Drum diameter, travel length, number of winding layers
- 3 Suspended length and weight How much cable hangs free, and the load at the free end
- 4 Abrasion environment Coal, ore, aggregate, refuse; presence of dust and grit
- 5 Conductor size and core count Power rating plus control and signal requirements
- 6 Outdoor conditions Wind exposure, temperature range, UV, humidity
Frequently asked questions
What makes bulk handling cable different from a standard reeling cable?
The jacket. On a stacker or grab crane the dominant wear is abrasion from coal, ore or aggregate over a large area, so the compound is selected for abrasion resistance and often for a thicker or reinforced outer layer, alongside the tensile reinforcement the long travel requires.
How do I size tensile reinforcement for a long boom?
From the suspended length and the weight per metre of cable, plus the dynamic factor of the machine. Give us the boom length and the cable diameter you need and we will confirm the reinforcement type and core construction.
Can one cable serve both the boom and the grab?
It can where the duty is similar, but grab and trolley duties often differ in bend radius and tensile load. We normally confirm each run separately and only combine them if the specification data supports it.
What core construction suits winding in many layers?
A construction that resists compression — tight, filled cores with a defined core geometry — so that lower layers do not deform under the weight above them. Tell us the number of layers you wind and we will match the core type.

Need the cable confirmed against your machine?
Send the duty, the environment and the electrical data. Our engineering team will confirm the construction, the standards it meets, and the price — including custom builds where a catalogue type does not fit.
