Hydraulic Shears
Hydraulic Shears GRABIRON®
GRABIRON® special hydraulic shears are a modern British-Ukrainian product certified under ISO 9001 international quality standards and Ukrainian Technical Specifications TU U 84.6-13425008-008. Special shears are manufactured in various types depending on their application — cutting and crushing reinforced concrete structures during demolition. Operating ambient temperature ranges from -40°C to +40°C (GOST 15150-69) in environments free of chemically active gases, vapors, or dust that degrade metals and electrical insulation.
GRABIRON® special hydraulic shears feature a two-jaw attachment design engineered for continuous heavy-duty demolition work over extended periods. Exceptional cutting power combined with a rapid cycle time ensures maximum productivity. Depending on operational requirements, the structural frame of the shears is fabricated from 09G2S, 10KhSND, and HARDOX (450, 600) steel grades. Our structural steel fabrication meets the quality standards of the German company Epiroc, as our manufacturing plant produces structural components for Epiroc excavator attachments.
GRABIRON® special hydraulic shears — quality: manufactured in strict accordance with Ukrainian Technical Specifications (TU U), fully refined, and thoroughly field-tested under heavy-duty conditions of scrap processing and demolition of decommissioned industrial facilities. Key clients include scrap recycling companies and major construction firms. In design, materials, and operational performance, the product not only matches German equivalents but surpasses them across several parameters. Our product has zero weak spots. Its simplicity of maintenance and operation is impressive.
GRABIRON® special hydraulic shears — versatility conforming to international standards. The shears were engineered so that the rotator, cylinders, hoses, pins, protective covers, and bolts are interchangeable with widely used imported equivalents, making seamless integration into your machinery fleet exceptionally convenient.
GRABIRON® special hydraulic shears — unrivaled cost efficiency. While most Western European competitors assemble shears from outsourced components, our plant maintains a complete full-cycle manufacturing process — including casting and final assembly — sourcing only two primary assemblies externally: hydraulics (Italy) and rotators (Sweden).
GRABIRON® special hydraulic shears — complete warranty and service coverage. When shears break down, foreign manufacturers often attribute failure to improper operation by the Customer, resulting in warranty denial — alongside complex re-export procedures required for overseas repairs. Located in central Ukraine, our manufacturing plant is ready to resolve issues quickly and return equipment to operation. Our warranty coverage is 12 calendar months from the date of delivery, backed by post-warranty service support. The operational lifespan is at least 5 years. Components and spare parts are supplied directly from warehouse inventory and can be delivered anywhere in Ukraine within 24 hours at competitive rates.

Frequently Asked Questions (FAQ)
The lifting capacity of an electromagnet is the maximum load weight permitted to be lifted and moved by the magnet. It typically equals 0.5 of the breakaway (tear-off) force, providing a safety factor for secure operation.
The lifting capacity depends on the magnitude of the magnetic flux in the core. The flux increases as the magnetomotive force increases and as the magnetic reluctance of the circuit decreases.
Copper coils cost twice as much as aluminum ones; copper has 1.7 times higher conductivity than aluminum; copper density is 3.3 times higher than aluminum; copper’s specific heat capacity is 3 times lower than aluminum’s; copper coils offer more repair cycles and a longer service life than aluminum.
Welded steel housings are simple and cost-effective to produce. The advantages of a cast magnetic core over a welded one include cooling fins, greater operational durability, solid structural integrity, and the complete absence of internal air gaps.
Overheating, lower density of scrap metal, switching to metal stock with larger air gaps, and malfunctions in the control cabinet (voltage converter).
Improper operation (faulty control cabinet, overheating, moisture exposure, overvoltage), coil-to-housing breakdown (ground fault), open-circuit/broken conductors, and inter-turn short circuits within the coil.
