Propsetter®

  • 001

    What is it?

    Timber standing prop support with a built-in yield-zone

  • 002

    Yielding

    The yield-zone enables safe deformation under load, preventing buckling and breaking

  • 003

    Low cost

    Simple timber support with improved materials handling and fast installed support

  • 004

    Pre-stressing

    Power Wedge, a mechanical pre-stressing device, fits onto Propsetter to apply active pre-loading up to 10 US tons

Link-N-Lock™

  • 001

    What is it?

    High-capacity, interlocking timber blocks stacked in layers floor-to roof

  • 002

    Unique
    Design

    Engineered notches create 100% contact between layers, significantly increasing strength and stability

  • 003

    Stable
    Support

    Available in 2-and 3-notch options. The longer the blocks, the stronger and more stable the support system. Ideal for areas exceeding 10 feet (3m)

  • 004

    Efficient

    100% contact uses 50% less timber for the same support capacity as competitor products

Cluster Prop™

  • 001

    What is it?

    High-capacity, high yielding timber standing support prop, formed by bundling three Strata Propsetters and binding with pre-tensioned metal straps

  • 002

    High
    Strength

    Available in lengths up to 10ft (3m) and in three load capacities: 100 to 250 US tons

  • 003

    Yielding

    Offers up to 16in (400mm) of stable deformation for unmatched safety

  • 004

    Transport
    & Handling

    Specialized system bundling for optimized transport and handling. Improves haulage productivity up to 70% compared to comparable support capacity roof supports

Rocprop®

  • 001

    What is it?

    Compact mechanical steel prop that provides active support using hydraulic pre-loading and safe yielding under load

  • 002

    Versatile

    Countless applications in all types of mining and underground construction. Can be installed vertically, horizontally or at an angle

  • 003

    Support

    Extends hydraulically to roof height and applies active pre-load for enhanced performance. Suitable for heights up to 60ft (6m)

  • 004

    Yielding

    High load-bearing capabilities and stable yield make it suitable for high closure and seismic mining environments

Sand Prop™

  • 001

    What is it?

    Ultra-compact, self-contained steel prop that can be installed by one person

  • 002

    Support

    Consistent 60 US ton support with 2 inch controlled deformation

  • 003

    Design

    Engineered adjustability. Each prop offers 2 feet of height extension

  • 004

    Low cost

    Fast, immediate support installable by one person. Optimal handling, no tools or equipment required

Donut Cribs™& Cribpacs®

  • 001

    What are they?

    E.Dillon patented high capacity circular concrete supports

  • 002

    Fiber
    Reinforced

    Cut-able fiber reinforced concrete ideal for longwall moves, or for permanent, non-degradable roof support

  • 003

    Support

    Stacked in layers, blocks provide dimensional stability, increased strength and stable yielding for active ground conditions

  • 004

    Handling

    Cribpacs® are pre-packaged stacks of 4, 5 and 6 layers with plywood for yielding and easier mechanical handling

  • 001

    What are they?

    E.Dillon patented high capacity concrete supports

  • 002

    Fiber
    Reinforced

    Cut-able fiber reinforced concrete ideal for pre-driven recovery rooms, or permanent, non-degradable roof support

  • 003

    Stable
    Strength

    Stacked in layers blocks provide dimensional stability, increased strength and stable yielding for active ground conditions

  • 004

    Handling

    CribStacs® are 24” x 24” pre-bundled stacks with plywood for yielding and easier mechanical handling
