About ECHLE Hartstahl
ECHLE Hartstahl GmbH is a medium-sized company founded in 1994 in Wolfach, specializing in attachment tools, conversions, custom designs and protective equipment for construction machinery. The portfolio includes patented cab protection grilles (FOPS according to ISO 10262), cylinder guards, boom, undercarriage, counterweight and cab modifications as well as retrofit electrification of construction machinery with trailing cable, battery or hybrid drive. Manufacturing covers engineering, material cutting and bent parts, welding with welding supervision, machining up to a turning length of 4 m at 1.60 m diameter, CNC large-hole drilling, straightening work, painting and powder coating as well as hydraulics and electrics integration. Materials processed are predominantly steels such as S235J2G3, S355J2G3, fine-grain steels and high-strength alloy steels, complemented by polycarbonate for protective glazing. Customers come from construction machinery manufacturing and trading, demolition, vehicle recycling, metallurgy as well as road and highway construction; a mobile drilling and welding team enables repairs directly on site at the customer's premises. The company operates two plants in Wolfach and serves customers worldwide.

Materials & Processes
S235J2G3 (structural steel)
Base material for welding, repair and steel construction work on construction machinery components.
S355J2G3 (structural steel)
Higher-strength structural steel for load-bearing structures such as booms, frames and undercarriages.
Fine-grain structural steels
For wear- and load-critical components with high demands on weldability.
High-strength alloy steels
Used in attachments such as shears, pulverizers and demolition tongs.
High-pressure pipes
Welded pipe components for hydraulic applications.
Polycarbonate
Material for FOPS cab protection structures and special safety glazing.
Copper
Material of wiring harnesses in electrification projects and for material separation in vehicle recycling.
