Stacker Reclaimer

What is a Stacker Reclaimer?

A Stacker Reclaimer is a cornerstone of modern bulk material handling, found in stockyards at ports, mines, and power generation plants. This massive, rail-mounted machine performs the dual functions of “stacking” (building stockpiles of materials like coal or iron ore) and “reclaiming” (loading those materials for transport or processing). Given their immense size, high capital cost, and central role in the supply chain, their operational reliability and safety are of paramount importance.

The Unique Braking Challenges of a Stacker Reclaimer:

The sheer scale and operational complexity of these machines present a unique set of braking challenges that demand a holistic and robust solution. The key requirements include:

• Controlling Massive Inertia: The long travel motion of a fully-laden stacker reclaimer involves immense kinetic energy. Braking must be smooth and controlled to prevent structural shock and ensure precise positioning.
• Absolute Static Security: When not in operation, the machine must be securely anchored. Its large surface area makes it extremely vulnerable to high winds, which can cause uncontrolled movement and catastrophic derailment.
• Multiple Motion Control: Beyond long travel, the slewing (rotating) and luffing (lifting/lowering) of the boom must be precisely controlled and held securely in place, often under heavy load.
• Fail-Safe Redundancy: On every critical motion, the braking system must be inherently fail-safe, engaging automatically in the event of a power loss to prevent any unintended movement.

A Comprehensive Braking Strategy:

A single type of brake is insufficient. A complete braking strategy for a stacker reclaimer involves several specialized systems working in concert:

• Long Travel Drives: This primary axis requires both dynamic service brakes for routine stops and powerful Storm Brakes (such as our YJGQ Rail Clamps or YFX Wedge Brakes) for secure parking and wind protection.
• Slewing and Luffing Drives: These motions rely on high-torque, fail-safe holding brakes, often SH Series Hydraulic Disc Brakes or heavy-duty drum brakes, to lock the boom in position.
• Internal Conveyor Systems: The conveyor on the boom also requires its own braking system to control the flow of material, especially on inclined sections.
