Industrial Silo & Confined Spaces Specialists

Precision Engineering at Height | South Africa’s Leaders in Rope Access Silo Solutions

At OnPoint SkyRiders, we provide elite Industrial Rope Access (SDR) services for the most challenging vertical hazardous environments. From massive concrete grain terminals to specialized chemical storage, our IRATA-certified High-altitude rescue specialist utilize advanced twin-rope systems to deliver cleaning, maintenance, and structural repairs with zero reliance on costly scaffolding.

Specialized Silo Infrastructure Care

A silo is a high-stakes asset. Whether constructed of reinforced concrete, bolted steel, or fiberglass, these structures are vulnerable to internal material “hang-ups” and external atmospheric corrosion. Without proactive vertical maintenance, silos face structural compromise and costly operational downtime.

Eliminating Flow Obstructions & Blockages

Our high-angle technicians are experts in restoring flow via rope-supported mechanical agitation. We clear:

  • Bridging (Arching): Breaking stable arches across discharge outlets using controlled descent techniques.
  • Rat-Holing (Tunnelling): Removing stagnant “dead zones” from internal walls to restore “First-In, First-Out” (FIFO) capacity.
  • Caking & Crusting: Utilizing chisel-scaling and high-pressure hydro-blasting to remove hardened mass and biohazard contaminants.
  • Segregation Issues: Correcting irregular unloading patterns that threaten structural equilibrium.

Our Technical Service Suite

Advanced Silo Hygiene & Cleaning

Internal Descaling: Specialized removal of tough oxidation and product buildup using rope-access manual scraping.

Confined Space Entry (CSE): Our teams are masters of Hazardous Atmosphere Entry, equipped with gas detection, specialized breathing apparatus, and pre-rigged rescue systems.

Sanitization: High-standard cleaning for food-grade compliance (HACCP-ready).

Structural Integrity & Remedial Repairs

Concrete Refurbishment: Repairing spalling, carbonation, and exposed rebar at any height.

Protective Coatings: Application of industrial-grade epoxies and UV-stable paints via vertical specialized application.

Component Replacement: Hot-swapping rusted flanges, vents, and internal pipework using heavy-lifting rope rigging.

High-Precision Inspections

Non-Destructive Testing (NDT): Ultrasonic thickness testing and visual structural audits performed via aid climbing and traversing.

SkyEye Drone Surveys: Rapid 4K thermal and visual data capture for a 360° view of your asset.

The OnPoint Rope Access Advantage

Why swap scaffolding for the SkyRiders?

  • Rapid Mobilization: We rig and descend in the time it takes to deliver one scaffold pole.
  • Unmatched Versatility: Our technicians navigate complex geometries and spherical bulk storage that traditional lifts simply cannot reach.
  • Zero Footprint: No ground-level obstruction. Your site remains 100% operational while we work above.
  • Elite Safety Standards: We operate under a redundant dual-rope protocol. Statistically, rope access is the safest way to perform work-at-height in South Africa.

Cost Efficiency: Eliminate “dead-time” rental costs. Save up to 60% on your maintenance budget by paying for the work, not the equipment.
