Cutting Cycle
Illustration 4 g06096578
(A) New Cutters
(B) Cut Thin Materials First
(C) Cutting Thicker Materials
(D) Cut Abrasive Materials Last
New Cutters
Cut thin materials first
Sheet less than ¼ in (6 mm) thick, white goods, mixed scrap
Cutting thicker materials
Structural steel, beams, plate, farm equipment
Cutting abrasive materials
Rebar is very abrasive to blades and may shorten the structural life of the shear
Cable is abrasive to blades
Cutting specialty materials
Stainless steel reduces the cutting capability of the shear by 50-80%
Railroad rails should not be cut under any circumstances
Concrete is very abrasive to jaws and blades depending on the strength
Cast ferrous metals are very abrasive to blades
Thin walled cast is acceptable (for example, pipe)
Heavy cast is not recommended (for example, machining centers)
Tires are dependent on cable size around bead, consult your Cat dealer for recommended shear size
Cutting hardened materials
Materials above 42 Rockwell C are not recommended (for example, axle housings, axles, motor shafts, cylinder rods, etc.)Cutting Techniques
When reducing scrap or demolishing a structure, place the fixed jaw against the object to shear. Cut the object by moving the cutting jaw.
Position the material as close to the throat as possible, without using the machine force. Cutting force increases closer to the throat.
Beams can best be cut when oriented as shown.
Illustration 5 g06114304Piercing Material
When used properly, the bolt on piercing tip edge will have a service life which is comparable to the life of the cutting blade edges. Improper use of the piercing tip may result in catastrophic failure of the piercing tip and result in damage to the mating surfaces on the moveable jaw. Proper operation is critical to ensure maximum life of the piercing tip.
Hardened material should not be pierced or cut. Processing hardened material will decrease the life of the cutting components and may result in catastrophic failure.
Cutting of hardened material increases the risk of flying debris. Flying debris from the work tool could cause serious injury or death.
Illustration 6 g06100806Position material so that the piercing tip makes complete and even contact with the material being pierced as shown in illustration 6.
Illustration 7 g06100807Do not pierce with only a portion of the piercing tip engaged as shown in illustration 7. Piercing with only a portion of the piercing tip causes uneven loading and stress concentrations which can lead to piercing tip failure.Material Handling
Failure to adhere to proper material handling techniques may lead to premature failure of the piercing tip.
Illustration 8 g06100811Ensure the piercing tip is captivated by the lower jaw before handling material with the shear.Out-of-balance Loads
A load that is significantly out-of-balance can cause unwanted rotation of the shear. Keep loads centered at all times. Illustration 9 demonstrates a balanced load.
Illustration 9 g06114273Lifting Objects
Standard machine load charts do not account for weight of the shear. Contact your Cat dealer representative for any lifting capacity questions.
