Bolt Punch Auxiliary Hanger Adjustable Safe Lifting for Ball Mill Liner Replacement

HHBB01 Bolt Punch Auxiliary Hanger for Ball Mill Liner Replacement

HHBB01 auxiliary hanger is supporting equipment for hydraulic bolt punch. It suspends and positions the bolt punch on mill shell during liner replacement. It can adjust the punch up, down and horizontally to align the drill rod with liner bolts precisely. It reduces manual lifting work and improves operation safety, compatible with MC2-150B & MC3-250C bolt punch.

Product Highlights

Heavy-duty auxiliary hanger for hydraulic bolt punch. Stable suspension, precise adjustment, anti-drop safety design. Ideal for ball mill and SAG mill liner removal, greatly reducing labor intensity and improving operation safety.

Structure Composition

• Main welded frame: Box beam structure, fabricated by thick steel plate laser cutting, welding, shot blasting and painting.
• Rotary hinge base: Capable of pitching and horizontal rotation to adjust the angle of the bolt hammer for alignment with bolt heads.
• Load-bearing lifting lugs / hooks: For connection to temporary lifting points on the mill shell or the forearm of the liner replacement manipulator.
• Buffer and limit assembly: Absorbs hydraulic impact and prevents impact load from being directly transferred to lifting points.
• Quick-mount clamping seat: Rapidly clamps and secures the hydraulic bolt hammer for easy assembly and disassembly.

Key Applications

• Load-bearing suspension – Firmly supports MC2 / MC3 series hydraulic bolt punches and withstands continuous impact loads, removing the need for manual holding.
• Precise positioning – Features up-down and front-back fine adjustment to align the drill rod perfectly with liner bolt centers and ensure fully vertical punching.
• Vibration absorption & safety improvement – Absorbs partial impact vibration, reduces operator fatigue, and adapts perfectly to the curved surface of mill shells.

Structural Advantages and Features

• Heavy-duty welded steel structure – Adopts laser cutting, integral welding, shot blasting and plastic spraying treatment for excellent strength, wear resistance and corrosion resistance.
• Fast installation and flexible disassembly – Quick hook-on design fits narrow and complex on-site maintenance environments, saving preparation time greatly.
• Accurate adjustment mechanism – Ensures precise bolt alignment, avoids drill rod deflection, and effectively extends tool service life.
• Safety limit anti-drop structure – Prevents falling under strong impact force, providing stable and reliable performance for mining mill liner replacement work.
