The TEHMA SP400 (smallwedge variant) is a precision handheld hydraulic splitter delivering up to ~6080kN of splitting force through a compact, controlledfracture system. Paired with a compatible highpressure power pack, this kit is designed for environments where vibration, noise or dust must be minimized and access is limited.
Design:The TEHMA SP400 is a handheld highpressure hydraulic splitter engineered for controlled, vibrationfree demolition of concrete or rock.
- This smallwedge version (sometimes designated SP400SW) features a reduced required drillhole (3536mm) and narrower splitting gap (~10mm) while delivering a high splitting force (~6080kN) for confined or precision applications.
- Standard SP400 version specs: ~3620kN theoretical splitting force, splitting distance ~17mm, required drillhole diameter 4548mm, minimum depth 440mm, tool weight ~23.5kg, operating pressure 600bar.
- Built for durability and performance: cylinder and major components manufactured in aeronauticalgrade alloy; inner carbide layer for low friction and high wear resistance; highquality steel wedges; ergonomic handle; splitting direction controllable by handle orientation.
- The kit includes a power pack (hydraulic pump unit) to supply the required highpressure hydraulic fluid (typically up to 600bar) to operate the splitter effectively. For example: the TEHMA PP600 series (electric, pneumatic or hydraulic motor versions) are listed as compatible.
In summary: this tool offers heavyduty splitting force in a handheld format, optimized for jobs where vibration, noise or disturbance must be minimized, and where space or access is limited.
Applications:The SP400 smallwedge version with power pack is well suited for a variety of demanding and sensitive demolition tasks.
- Splitting large thickness concrete structures (foundations, thick slabs, pillars, retaining walls, bridge abutments) where controlled fracture is required without using blasting or large jackhammers.
- Breaking large rocks or boulders encountered in tunnelling, trenching, quarrying or utility excavations especially where blasting is undesirable or prohibited.
- Environments where low vibration, low noise and minimal dust are essential (e.g., hospitals, data centers, schools, historic buildings, luxury apartments).
- Confined space or restricted access jobs: upper floors, basements, indoors, underwater or near sensitive structures. The relatively modest weight (~23.5kg) helps with mobility.
- Rental fleets or contractors needing a turnkey kit (splitter plus power pack) for controlled demolition across varying environments.
