Product IntroductionMJY integral moving metal formwork, special shaft-sinking formwork with diameter of 4.5m-13.5m, designed for mine shaft construction, easy to assemble and disassemble.
MJY integral moving metal formwork dedicated vertical shaft concrete shaft wall lining equipment. Applicable coal metal mine vertical shaft construction, bedrock freezing zone key lining sections. Compact one-form multi-purpose design, efficient freezing shaft outer wall inner wall bedrock lining completion. Sharply cuts formwork replacement construction cost time consumption.
| Structural Features & Working Principle |
Body: Arc steel plate welded single-seam rigid cylinder. Sturdy structure. Components: Foot blade anti-leakage. Key part: hydraulic stripping device. Core: Hydraulic drive single radial seam. Synchronous, even opening/closing. |
Hydraulic stripping: Control cylinder via valve. Uniform shrink or expand at single port. Downward lining: After stripping, crane lowers template to next pour section. Foot blade positioning. Continuous pouring. Core value: Single-seam rigid structure + hydraulic synchronization. Efficient, high-quality shaft lining. |
MJY integral moving metal formwork: Hydraulic synchronous stripping: Precise control. Stable, efficient stripping. Single-seam rigid structure: Sturdy, foot blade anti-leakage. Accurate positioning. Continuous construction: Move down after stripping. Continuous pouring. High efficiency. |

Customer SiteProduct Details| Working Principle Initial Phase: Install the slipform at the shaft bottom and bind a section of reinforcement bars. |
Cyclic Operations: Pouring: Use bottom-dump buckets to transport concrete and pour it into the formwork in layers. Sliding: When the lowest layer of concrete in the formwork reaches initial setting strength (able to maintain shape but not fully hardened), activate the hydraulic jacks to slowly and continuously slide the entire formwork system upward by a certain distance (typically 10–30 cm per cycle). |
Repetition: Continue binding reinforcement bars, pouring new concrete, and sliding upward. This cycle enables uninterrupted and continuous construction of the shaft wall. |
