WHY USE RINGLOCK SCAFFOLDING SYSTEM IN A COAL HOPPER?

July 11, 2019
Thermal power plant managers must oversee the operations of a number of critical areas. Ensuring proper and adequate coal storage is just one of those responsibilities. However, when it comes time to construct a new coal hopper, or clean and service an existing hopper, extra resources are needed. That is where Ringlock Scaffolding System comes in.

The versatility of the Ringlock Scaffolding System

Ringlock Scaffolding boasts incredible versatility and can be built to suit any shape or size container or project. That is particularly useful in coal hoppers, which can often be awkward to work around and in. No matter the size of the access, you can get Ringlock Scaffolding Systems into a coal hopper.

In addition to versatility, Ringlock Scaffolding Systems also allow users to quickly and efficiently erect, use, and dismantle temporary work structures. This creates increased efficiency and productivity at a plant, and saves time and money by keeping operations on time and on budget.

How to erect the Ringlock Scaffolding System in tight spaces

Coal hoppers are traditionally built with a slope that feeds coal into a chute. Before erecting scaffolding inside the hopper, planks, or beams (wood planks for a brick hopper, base beams for a steel hopper) need to be secured to the wall so workers can climb the slope. Think of the planks as a makeshift ladder. Because the chute may run five to 20 feet deep into boilers, you also need to secure a lifeline or slack line for workers to attach themselves too.

Once you have taken the proper safety steps, you can begin erecting the scaffolding with this process:

  1. Start at the center line of the hopper and create a square base that will fit in the bottom, usually three 3×3 feet to 4×4 feet.
  2. Since the slope is very steep, start stepping out in all four directions with small bays for ease of erection.
  3. Place Swiveljacks on the slope.
  4. Place steel tubes to brace legs from sliding down the slope.
  5. Work your way out to the hopper walls to create planked working levels.
  6. Finish to the top of the hopper.
Ringlock meets or exceeds the highest American and European safety and durability standards. AT-PAC has manufactured the Ringlock Scaffolding System and associated components since 1995 and we maintain distribution warehouses all over the world, which saves you both time and money.
