    Product description

    Hydraulic counterblow hammer GH: The counterblow hammer GH is preferably used for particularly heavy parts demanding blow energies of more than 200 kJ.

    LASCO was pioneer and inventor of the hydraulic drive system for die forging hammers.

    When a blow is released the upper and lower ram are accelerated towards each other counter-directionally. The ratio of the masses of upper and lower ram is between 1:4 to 1:5, depending on the hammer size. As a result, the lower ram moves at a final speed of 1 - 1.2 m/s, delivering an impact speed of about 6 m/s. This aspect is particularly important for automation and when forging flat parts.

    Special features:
    - Most accurate repeatability of blow energy
    - Very low energy costs compared to air hammers
    - Automation facilitated by the stroke ratio of lower and upper ram (1:4)
    - Direct spring damping
    - Hydraulic drive in block design
    - Efficient programmable control system with operator guidance, product data administration and modem for remote diagnostics
