Q: How to confirm the Boom-Mount hydraulic excavator shear matches my 50-70T carrier perfectly as an excavator steel shear?
A: JISAN holds full hydraulic database for Sany, XCMG, CAT, Komatsu and all mainstream brands. Our technical team will match the JS550RT Boom-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 power shearing machine for heavy steel structures? Does it act like an industrial power squaring shear?
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. It delivers massive cutting force comparable to an industrial power squaring shear but with full mobility. Daily output increases by over 30%. Warranty expires at whichever comes first: 12 months service or 2000 working hours.
Q: What advantages does Hardox450 bring to these demolition steel shears? Are they the ultimate heavy scrap metal shear machine?
A: Shell and upper bracket of JS550RT adopt genuine SSAB Hardox450 wear-resistant steel. The blades are made of high-hardness alloy steel. As a true heavy scrap metal shear machine, it resists severe impact from thick steel plates. Cracked Hardox450 plates can be replaced free within 12 months under proper operation.

6-month: dual valve, pinion gear, gear cover
3-month: solenoid valve, pivot pins, pipelines
1-month: high-hardness alloy steel blades (only breakage covered)
Every unit passes 48 lab tests.
Q: How to choose between JS450RT and JS550RT as a power squaring shear? What’s the max cutting force of this power shear machine?
A: JS450RT fits 30–50T excavators, while JS550RT fits 50-70T excavators with extreme cutting force for thick ship plates and bridge girders. Unlike trading companies that just do wholesale concrete demolition crusher or shear imports, our excavator shear factory builds the JS550RT specifically for extreme heavy-duty power shearing applications.
Q: Service life of excavator shear blades and availability of power shear parts?
A: Double-sided alloy steel excavator shear 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 is normal consumable loss, bulk power 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 the shear head for excavator and excavator shear head shell plates?
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 & 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 is prohibited. 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 high-reach Boom-Mount work?
A: Rotating model functions as a scrap metal rotary shear for grabbing irregular steel from any angle at high altitudes, 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 bridge dismantling work, lubricate every 4 hours.
Q: Can the hydraulic shear excavator and metal shear excavator work underwater?
A: Long underwater use of the hydraulic shear excavator 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 Boom-Mount installation of the excavator hydraulic shear attachment be claimed?
A: Boom-mount requires specific auxiliary pipelines on the boom arm. New excavators fit the excavator hydraulic shear attachment directly, refit kits supplied for old machines. Motor & cylinder damage from self-modified oil circuit excluded.
Q: Will insufficient lubrication void the warranty for the metal shear attachment for excavator and excavator demolition shear?
A: Grease every 4 hours under heavy load for your metal shear attachment for excavator, full lubrication after long idle. Bearing & pin damage from lack of grease excluded.
Q: Anti-freeze steps for the demolition shear for excavator and hydraulic demolition shears?
A: 5–10 mins no-load warm-up below 0℃ for the demolition shear for excavator, low-temperature oil below -10℃. Cover machine outdoors. Freeze crack from poor maintenance excluded.
Q: Can rust from outdoor storage of the scrap metal cutting shears and scrap metal cutting shear 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?
A: Clean slag, coat the scrap iron shear Hardox shell with anti-rust oil, retract cylinders, wrap waterproof film indoors. Outdoor rust damage excluded.
Q: Which leakage 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 and excavator shear motor warranty?
A: Tooth breakage from insufficient grease excluded on the excavator shear attachment; motor shaft breakage from impact & self-tuning not covered.
Q: Freight & overseas lead time for excavator shear parts from your excavator shear supplier?
A: Free warranty excavator shear parts, all freight & tariff borne by buyer. As a reliable excavator shear supplier, overseas warehouse delivery is 3–7 days, sea 20–40 days, air for emergency 7–15 days.
Q: Can JS550RT be customized for long reach excavators? How does it compare to a hydraulic crusher with long boom arm?
A: Yes, JS550RT is ideal for long-boom setups. Unlike a hydraulic crusher with long boom arm which is strictly for concrete crushing, our Boom-Mount shear is engineered for high-altitude steel dismantling. As an oem excavator shear manufacturer, we customize flow rates for extended reach.
Q: Export process for excavator shear for sale and demolition shears for sale?
