Q: How to confirm the Stick-Mount excavator scrap metal shear matches my 50-70T carrier perfectly as a hydraulic shear for excavator?
A: JISAN holds full hydraulic database for Sany, XCMG, CAT, Komatsu and all mainstream brands. Our technical team will match the JS550RT Stick-Mount model according to your 50-70T excavator tonnage, calibrate pressure, flow and pin distance precisely to prevent host overheating. Any failure caused by operation beyond rated tonnage, pressure and flow will not be covered by warranty.
Q: What advantages does the 2.4s cycle bring when using this scrap shearing machine as a high-efficiency power shearing machine?
A: Ordinary shears take over 3.5s per cycle. JS550RT eagle shears are equipped with patented energy recovery speed valve, only 2.4s per cut. Daily output increases by over 30% under the same fuel and labor cost, shortening ROI greatly. Warranty expires at whichever comes first: 12 months service or 2000 working hours. Warranty period will be halved if daily working time exceeds 8 hours.
Q: What advantages does Hardox450 bring? What material are the scrap shear blades and excavator shear blades?
A: Shell and upper bracket of JS550RT adopt genuine SSAB Hardox450 wear-resistant steel. The scrap shear blades and excavator shear blades are made of high-hardness wear-resistant alloy steel. Cheap competitors only paste thin wear plates partially and suffer weld cracks within 3–6 months. Cracked Hardox450 plates can be replaced free within 12 months under proper operation.
Q: What full warranty & after-sales policies do hydraulic scrap shear manufacturers offer for overseas buyers looking for a scrap shear for sale?
A: Global unified 10-30-824 rapid service: 10 mins customer reply, 30 mins technical plan, spare parts dispatched within 8 hours, full troubleshooting within 24 hours.
12-month: shell, upper bracket, slewing bearing, hydraulic motor, cylinders, flow divider, speed-up valve
6-month: dual valve, pinion gear, gear cover, relay
3-month: solenoid valve, handle & foot switch, pivot pins, pipelines
1-month: high-hardness alloy steel blades (only breakage & peeling covered, wear & edge curling excluded)
Consumables (bolts, bearings, grease, fuses) no warranty. Every unit passes 48 lab tests.
Q: How does this heavy scrap metal shear machine compare to a stationary china scrap metal gantry shear or scrap shear baler?
A: Unlike a fixed china scrap metal gantry shear or a scrap shear baler that requires feeding material into a hopper, this Stick-Mount heavy scrap metal shear machine connects directly to the dipper arm. It moves freely around the shipyard or scrap yard, grabbing and cutting thick ship plates and bridge girders on the go without material preparation.
Q: Service life & reusability of alloy steel scrap shears blades? Warranty rule for these excavator shear parts?
A: Double-sided alloy steel scrap shears blades can be flipped for 3000–5000 hours under normal scrap work. Only 1-month warranty: free replacement for breakage & chunk peeling within 1 month. Uniform wear & edge curling are normal consumable loss, bulk excavator shear parts available.
Q: Core gap between cheap alternatives and JISAN JS550RT as a premium china excavator shear directly from our excavator shear factory?
A: Low-cost carbon steel frames crack quickly under 50T+ carrier pressure. JS550RT adopts integrated Hardox450 steel plus alloy blades with SSAB certificates. As a direct excavator shear factory, we guarantee structural integrity that cheap alternatives cannot match.
Q: Warranty repair rule for cracked Hardox450 shell plates on the shear head for excavator and excavator shear head?
A: Free component replacement for original crack within 12 months on the excavator shear head. Reimburse 200 RMB welding cost for weld crack within 6 months. Welding guidance offered, all freight borne by buyer. Cracks from overload, self-modification & impact excluded.
Q: Can this demolition shears excavator setup cut concrete? How does it compare to an alligator shear for excavator?
A: Only exposed rebar can be cut. Solid concrete & rock are prohibited to avoid fast blade wear. Unlike an alligator shear for excavator which struggles with thick I-beams, the JS550RT eagle-beak design provides massive piercing force for heavy steel structures. Use pulverizer for concrete.
Q: Why choose a rotating scrap metal rotary shear over a fixed scrap steel rotary shear for heavy yard work?
A: Rotating model functions as a scrap metal rotary shear for grabbing irregular ship hulls and pipes from any angle, while fixed models lack this flexibility. Both Hardox450 shell & alloy steel blades with identical warranty. Rotating version is heavier, slewing bearing 12-month warranty.
Q: Will warranty be shortened under 24h operation for these demolition scrap shears and general demolition shears?
A: Full 12-month warranty for 8-hour single shift. Daily work over 8 hours halves warranty for these demolition scrap shears. Custom thickened Hardox jaws recommended for non-stop ship dismantling work, lubricate every 4 hours.
Q: Can the hydraulic scrap metal shear work underwater? Will silt rust be covered?
A: Long underwater use of the hydraulic scrap metal shear is not recommended. Full cleaning & greasing required after underwater work. Rust & jamming from poor maintenance excluded. Anti-corrosion custom model available.
Q: Can faults from improper Stick-Mount installation of the excavator hydraulic shear attachment be claimed?
A: New excavators fit the excavator hydraulic shear attachment directly to the stick (dipper arm), refit kits supplied for old machines. Motor & cylinder damage from self-modified oil circuit excluded. Standard installation takes 2–3 hours.
Q: Will insufficient lubrication void the warranty for the metal shear excavator setup?
A: Grease every 4 hours under heavy load for your metal shear excavator setup, full lubrication after long idle. Bearing & pin damage from lack of grease excluded.
Q: Anti-freeze steps for cold weather when operating the scrap shear with excavator for sale?
A: 5–10 mins no-load warm-up below 0℃, low-temperature oil below -10℃. Cover machine outdoors. Freeze crack from poor maintenance excluded.
Q: Can rust from outdoor rain storage of the scrap metal cutting shears be claimed?
A: Anti-rust coating applied before delivery of the scrap metal cutting shears. Rust from uncovered rain storage excluded.
Q: Standard idle storage steps for the scrap iron shear and scrap steel shear when unmounted?
A: Clean slag, coat the scrap iron shear and scrap steel shear Hardox shell with anti-rust oil, retract cylinders, wrap waterproof film indoors. Outdoor rust damage excluded.
Q: Which leakage & slow movement faults are covered for the hydraulic shear attachment for excavator and metal shear for excavator?
A: Factory valve & cylinder defects of the hydraulic shear attachment for excavator are covered for 12 months. Damage from self-adjusted pressure & dirty oil excluded, spare parts shipped within 8 hours.
Q: Exemption for the excavator shear attachment & motor 12-month warranty?
