Hydraulic GWW field clamp for civil engineering work to optimise the use of your mini or midi machine. Compact, tough and durable. The low weight and coupling height of the half-pack brick and block clamp optimise the residual loading capacity/stability and lifting height of your machine. It is fitted with extra guard plates to protect the cylinder rod from getting damaged. In other words, the GWW field clamp is a little powerhouse on the construction site.

  • Extensions
  • Paver plates
