New Cat scrap shears enhance productivity

Published 7/3, 2019 at 17:11

Caterpillar Work Tools has expanded its range of excavator attachments with three new scrap shear models - S3015, S3025, and S3035 - which build on the company’s demolition and scrap processing technology experience.

Designed for hydraulic excavators with operating weights between 8t and 40t, the new Cat shears feature optimum force to weight ratios that yield faster cycle times and more cuts per hour when compared with predecessor models. The new shears join the rotating models S3050, S3070, and S3090 as well as the straight versions - S2050, S2070, and S2090 - in the Cat scrap shear range.

The new shears feature a dual offset apex jaw design, resulting in increased cutting performance and efficiency. The new patent pending bolt on the piercing tip of the upper jaw further enhances productivity when piercing is required, protecting the moving jaw and shielding parent metal from wear as the moving jaw travels through the lower jaw. Structural reinforcements more effectively distribute the shear’s cutting forces, and the apex jaw design, coupled with a larger jaw opening, results in greater cutting strength, especially when cutting profiles.

The powerful reverse cylinder is fully protected and allows a slim profile that improves visibility and manoeuvrability in tight spaces. The knives and guide blades have four cutting surfaces that can be rotated before replacement is necessary, whereas a heavy duty pivot group can be tightened with standard tooling to keep the jaws aligned as wear occurs. Furthermore the new shears are maintenance friendly and feature field serviceable swivel and pivot group, which also reduces downtime. The operator is able to adjust the side play in the field without the need for special tooling by only tightening the pin. The greasing of the shear, including stick cylinder and boom pin, can be done from ground level, making this work safer.

The S2000/S3000 are manufactured from alloy steel having superior yield and tensile strength properties which contribute to longer overall life. Knife maintenance, wear plate replacement, and tip build up can be addressed quickly and easily, and are designed to fit Cat excavators, as well as other brands, with operating weights from 8t to 85t+.
