SHEARS All Piranha Shear Models Provide: Guillotine design Single cylinder linkage system allows constant parallel alignment of beam throughout shearing movement. Extra-long, hardened ways, with adjustable non-metallic gibs, guide the ram laterally and front-to-back at all times during the shearing process to increase rigidity, shearing accurace, and blade life. The straight line shearing action improves shearing accuracy in all metal thicknesses. All pivot points are lined with maintenance-free bearings. These stat-of-the-art, aerospace bearings provide high load capacity and low friction in the form of a thin-walled sleeve. They are non-metallic and require no lubrication. The upper shear blade moves parallel to the lower blade, providing maximum blade life High carbon, high chrome four-edge blades, top and bottom. 120v controls with overload-protected magnetic motor starter and circuit breaker disconnect. Hardened, micro-finished oversize link pins. OUR COMPETITORS' DESIGNS Torque Tube Design The complex drive mechanism on the torque tube design requires the use of additional pivot points. Adjusting blade clearance after blade sharpening is extremely difficult. The design lacks rigidity, which affects blade life, shearing accurace, and shear service life. Swing Beam Design The upper blade moves at an arc in relation to the lower blade which reduces blade life when compared to Piranha's guillotine design. Typically, two rollers are used to control the lateral position of the shear ram. However, the ram is not guided front-to-back, which can affect blade clearance.
