Description

The TEHMA SP400 is a handheld high-pressure hydraulic splitter engineered for controlled demolition of concrete and rock. It uses a wedge-based mechanism: the cylinder advances a central wedge between two counter-wedges inside a pre-drilled hole, producing large splitting force without vibration, percussions or dust.

Design:

• The splitter unit weighs about 23.5 kg and operates at up to 600 bar pressure, delivering a theoretical splitting force of 3,620 kN.
• Required drill hole diameter ~ 45-48 mm (for the SP400 model) and minimum hole depth ~440 mm.
• Splitting gap (distance the material is forced apart) is ~17 mm for the SP400.
• Constructed with premium materials: cylinder and key components made in aeronautical-grade alloy, an inner carbide layer for low friction and durability, high-quality steel wedges, ergonomic handles and reversible control cam for controlled splitting direction.
• The kit version comes paired with a hydraulic power pack (TEHMA PP600 / PP700 series) to supply the required high-pressure hydraulic circuit.

In short: the SP400 provides heavy-duty splitting power in a compact handheld format, enabling controlled demolition in settings where traditional methods (jackhammers, blasts) might be impractical due to noise, vibration or space constraints.

Applications:The SP400 kit is designed for a wide range of demanding demolition or splitting tasks, especially where vibration, noise or dust must be minimized.

• Splitting thick reinforced concrete structures: foundations, floor slabs, pillars, bridge decks, retaining walls.
• Breaking large rocks or boulders in excavations, tunneling, quarrying or utilities routing.
• Jobs in sensitive environments (hospitals, data centers, offices, luxury residential buildings) where low noise, low vibration and minimal dust are required.
• Situations of limited access, upper floors, interior demolition, underwater or confinedspace operations, where large or heavy equipment is impractical.
• Rental fleets or contractors needing a complete kit that integrates the splitter and hydraulic power pack for immediate deployment.
