Mini Alligator Shear

A movable shear is useful when location flexibility is worth the repeated transport and setup effort. Assess that total process against a stationary loading point, including power, support, access and inspection after positioning. The ability to relocate equipment does not remove the need for an approved operating area.

Compare relocation method, setup requirements, power arrangements, site support and maintenance access. Mobility does not remove the need for an approved operating area. Confirm how the proposed machine is transported, positioned and prepared before each period of use.

Copper and aluminium scrap may be suitable for a particular shear, but their deformation and handling can differ from the steel duty used in a reference rating. Define alloy, shape and required output quality. Keep commercial grade separation in the assessment as well as mechanical capability, particularly where the cut material goes to a controlled recycling stream.

Confirm the exact alloy and geometry and consider grade separation. A shear chosen for steel should not be assumed optimised for every non-ferrous duty. Trial cutting can help establish output quality and practical handling where the requirement is unusual.

Cutting force must be assessed from the actual cross-section and material, not its outside dimensions alone. A hollow tube and a solid bar of the same diameter create different duties. Supply the difficult normal sections and known material properties so the proposed shear can be assessed as a complete blade, structure and hydraulic combination.

• Material grade or known strength.
• Solid, hollow or built-up cross-section.
• Maximum wall or plate thickness and width.
• How the piece is presented to the blades.
• Required cut length and sustained production.

Provide section drawings, thickness, alloy and maximum dimensions. The machine supplier should define approved material limits for the selected shear. Avoid treating a force number as permission to cut any object that fits.

No single thickness figure covers every material and section. A plate rating without width or grade leaves out part of the cutting problem, just as tube diameter leaves out wall thickness. Ask for the reference section behind the rating and the approved limits for your scrap before assuming equivalent capability.

Why geometry matters: a tube's outside diameter does not describe its wall thickness, and a plate's thickness does not describe its width. A rating based on one reference section cannot be transferred directly to a different shape.

Submit the largest and most demanding normal sections, including drawings where available, for an application-specific assessment.

Ask what reference material and geometry support the rating. For mixed scrap, identify the difficult sections and assess them explicitly. The approved operating envelope is more useful than a single headline maximum.

Hazardous or unidentified objects must be segregated before the cutting stage. A metal exterior does not establish that a container is empty, depressurised or free of reactive contents. The approved scrap specification and site acceptance procedure should also exclude sections outside the machine's strength and dimensional limits.

Also identify objects outside the approved strength or dimensional limits. Material inspection and the site's acceptance procedure are part of safe scrap preparation. Never use the shear to discover what an unidentified object contains.
