Product Variants
?? LLS – Jacking Frame Type
Based on Herrenknecht’s proven pipe jacking technology, this configuration uses a hydraulic jacking frame to lower, lift, or press the lining rings during shaft construction.

• Application: Vertical or inclined shafts in fractured or stable geology
• Mechanism: Retractable grab pins hold and move lining rings precisely
• Compatibility: Suitable for both new and retrofitted lining rings with integrated grab pockets
• Benefits: Allows controlled pressing of lining rings under challenging geological conditions

Typical Applications:

• Shaft lining after raise boring or boxhole boring
• Shaft maintenance or lining replacement
• Lining installation in complex geological settings

?? LLS – Strand Jack Type
This configuration employs strand jack technology, similar to Herrenknecht’s Vertical Shaft Sinking Machine (VSM) systems.
It uses multiple strand jack units symmetrically arranged around a circular base frame to handle heavy loads with exceptional precision.

• Load Capacity: Up to 200 tons per strand jack unit
• Setup Flexibility: Adjustable from 0°–90° around the shaft edge
• Configuration: 2–3 strand jack units depending on shaft depth and available space
• Modular Design: Enables fast adaptation to site-specific conditions

Typical Applications:

• Lining installation in vertical shafts with stable geology
• Integration with boxhole backreaming or raise boring systems
• Efficient post-sinking lining installation

Performance & Safety

• Automation Integration: Remote and digital monitoring ensures precision during lifting and lowering operations
• Safety Enhancement: Reduces on-site human exposure and manual intervention
• Versatility: Customizable for varying lining materials, geological profiles, and shaft depths

System Integration
The LLS can be combined with Herrenknecht BBR systems to enable simultaneous drilling and lining, optimizing project timelines and minimizing ground disturbance.

Applications

• Construction of access and ventilation shafts
• Sewer, utility, and metro infrastructure projects
• Mine and tunnel shaft lining operations
• Rehabilitation or replacement of existing shaft linings

Summary
The Herrenknecht Lining Lowering System (LLS) redefines shaft lining efficiency and safety through mechanization, precision control, and adaptability. Whether configured as a Jacking Frame System or Strand Jack System, it ensures fast, controlled, and safe lining installation in vertical and inclined shafts across all geology types.

1. 
   Innovative Separation Mechanism: Crafted with precision, the machine comprises a fixed chassis and vibrating body working in tandem. The stone separator, designed to account for the varying densities of stones and grains, employs vibration to guide grains against or with gravity, effectively separating stones. Wheat is then seamlessly sifted from the stones using a vibrating sieve.
   


2. 
   Dust-Free Purification: Going beyond mere separation, the system incorporates air aspiration from the ventilation line, ensuring the absorption and removal of dust. This dual-action process guarantees not only the elimination of foreign materials but also the delivery of a pristine, dust-free end product.
