Our OTR dismantling machine is a heavy-duty, specialized piece of equipment engineered specifically for processing giant Off-the-Road (OTR) tires. Its core function is to safely and precisely cut massive mining and construction vehicle tires into 4 to 6 smaller, more manageable sections (such as the bead, tread, and sidewalls). For any business involved in giant tire recycling, pyrolysis, or shredding, this machine is the indispensable first pre-treatment step, solving the core industry problem of OTR tires being too large to be fed directly into standard tire shredders.
Why Is an OTR Dismantling Machine Required?
OTR tires, also known as earthmover or mining tires, are the most difficult to process in the tire recycling industry due to their immense size, ultra-thick rubber layers, and heavily reinforced steel structure.
- Exceeds Size Limits: Their diameters can reach several meters and they can weigh several tons, far exceeding the infeed opening of conventional scrap tire shredders.
- Extremely Robust Structure: The exceptionally thick tread and sidewall rubber, combined with multiple layers of high-strength steel cord, place extreme demands on any cutting equipment.
- High Safety Risks: Any form of manual cutting is extremely dangerous, highly inefficient, and practically impossible.
Working Principle of OTR Tire Sidewall Cutter
Our OTR dismantling machine utilizes a powerful hydraulic or mechanical system to drive a high-hardness cutting blade, systematically breaking down a securely mounted tire:
- Tire Mounting: First, the giant OTR tire is lifted and securely fastened onto the machine’s work platform using lifting equipment.
- Positioning & Cutting: The operator uses a control system to move the special cutting blade, made from tungsten steel alloy, to a preset position (e.g., where the bead meets the sidewall).
- Dismantling Process: The cutting cycle is initiated. The blade, with immense force, smoothly and precisely penetrates the tire’s structure. Through platform rotation or blade movement, the machine sequentially separates the tire’s bead, sidewalls, and tread.
- Sectioning Complete: The entire tire is dismantled into 4-6 sections. These significantly reduced tyre blocks can then be processed further in tyre shredders and rubber cracker mills.

Key Advantages & Features of OTR Tire Sidewall Cutter
- Powerful Processing Capability: Specifically designed to handle the largest engineering tires, easily tackling a range from R35 up to R63.
- Efficient Cutting, Time-Saving: Depending on the tire size and thickness, dismantling a giant tire takes only 7 to 30 minutes, far surpassing any other method.
- Ultra-Durable Blade: The cutting blade is crafted from a special Tungsten Steel Alloy, offering exceptional hardness and wear resistance to ensure it stays sharp and has a long service life, even when cutting high-strength tires.
- Greatly Enhanced Safety: Mechanized operation completely replaces high-risk manual cutting, fundamentally ensuring the safety of operators.
- Enables Downstream Processing: The sectioned tire blocks are a suitable size to be fed directly into large, heavy-duty shredders, making this machine the key to unlocking the entire OTR tire recycling workflow.
- Robust Structural Design: Weighing several tons and welded from heavy-gauge steel, the machine’s structure is incredibly stable, built to withstand the immense forces generated during the dismantling process.
