Onboard Temporary Support Equipment

Onboard Temporary Support Equipment for Tunneling Operations

Onboard Temporary Support Equipment is a vital solution in modern tunneling projects. It replaces traditional pipe installation and forepoling support methods, providing an efficient and safe alternative for tunneling operations. This equipment is designed to enhance worker safety and tunneling efficiency, with an easy integration into mechanized support systems.

Key Features of Onboard Temporary Support Equipment

1. Compatibility with Roadheader Models
   The onboard temporary support equipment is compatible with most roadheader models currently available in the market, making it a versatile solution for a variety of tunneling needs.

2. Customizable Roof Beam Support
   The roof beam support system is highly adaptable and can be customized to meet the specific requirements of the roadway conditions and the client’s needs. This flexibility ensures optimal performance in various tunneling environments.

3. Minimal Modification to Roadheader
   The support system allows for efficient placement and easy integration of supporting facilities. It requires minimal modifications to the roadheader, ensuring that the movement and cutting functions of the roadheader remain uninterrupted.

4. Reduced Labor Intensity and Enhanced Safety
   Mechanized support operations significantly reduce labor intensity and offer a large support area. This minimizes the risk to bolting workers and boosts tunneling efficiency, all while ensuring worker safety during construction.

5. Efficient Hydraulic System
   The onboard temporary support shares a hydraulic pump station with the roadheader for convenience. However, a separate hydraulic pump station can be provided upon request to meet specific operational needs.
