Q: How to confirm the Boom-Mount hydraulic eagle shear matches my 70-100T+ carrier perfectly as an excavator scrap shear?
A: JISAN holds a full hydraulic database for CAT, Komatsu, Sany, Volvo and all mainstream 70-100T+ mega excavators. Our technical team will match the JS800RT Boom-Mount model according to your carrier's massive tonnage, calibrating pressure and flow precisely to prevent host overheating. Any failure caused by operation beyond rated tonnage will not be covered by warranty.
Q: What advantages does the 2.4s cycle bring compared to an industrial concrete crusher for heavy demolition?
A: Ordinary shears take over 3.5s per cycle. JS800RT eagle shears achieve 2.4s per cut. Unlike a slow industrial concrete crusher which is strictly for breaking massive concrete foundations, this scrap shearing machine slices through thick bridge girders and ship hulls instantly, boosting daily steel output by over 30% in mega-projects.
Q: What material is used for these heavy-duty scrap metal cutting shears?
A: Shell and upper bracket of JS800RT adopt genuine SSAB Hardox450 wear-resistant steel. The cutting edges are made of high-hardness alloy steel. As premium scrap metal cutting shears, they resist severe impact from thick structural steel, ensuring structural integrity lasts much longer in extreme environments.
Q: As a leading demolition pulverizer company and shear manufacturer, what warranty do you offer?
A: Global unified 10-30-824 rapid service: 10 mins customer reply, 30 mins technical plan, spare parts dispatched within 8 hours.
12-month: shell, upper bracket, slewing bearing, hydraulic motor
6-month: dual valve, pinion gear
3-month: solenoid valve, pivot pins
1-month: alloy steel blades (breakage covered)
Every unit passes 48 lab tests.
Q: How does this JS800RT compare to a fixed chinese scrap metal baler shear or chinese scrap metal shear baler?
A: Unlike a stationary chinese scrap metal baler shear or a chinese scrap metal shear baler that requires massive foundation setup and material feeding, this Boom-Mount JS800RT brings extreme cutting force directly to the scrap pile or shipyard. It replaces the need to buy a fixed scrap shear baler for sale in many mobile heavy-duty applications, saving millions in infrastructure costs.
Q: Service life of scrap metal shear blades and availability of excavator shear parts?
A: Double-sided alloy steel scrap metal shear blades can be flipped for 3000–5000 hours. Only 1-month warranty: free replacement for breakage within 1 month. Uniform wear is normal consumable loss, bulk excavator shear parts available for quick global shipping.
Q: Core gap between cheap alternatives and JISAN as direct scrap shearing machine manufacturers?
A: Cheap mega-shears often use weak domestic steel that bends at the pivot points under 70T+ cylinder force. As direct scrap shearing machine manufacturers, JISAN uses integrated Hardox450 steel and reinforced forged linkage arms, guaranteeing the JS800RT will not deform under maximum host pressure.
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. Cracks from using the shear as a hammer or pry bar excluded.
Q: Can it process concrete? Should I use hydraulic pulverizers for construction demolition instead?
A: Only exposed rebar can be cut. For massive concrete pillars in bridge or factory demolition, you must use hydraulic pulverizers for construction demolition or a specific demolition pulverizer for construction. The JS800RT is strictly for heavy steel structures; using it on solid concrete will destroy the blades.
Q: Why choose a rotating model over a fixed one, similar to choosing a rotational hydraulic pulverizer?
A: Just like a rotational hydraulic pulverizer allows precise rebar separation from any angle, our rotating eagle shear grabs irregular steel pipes and ship hulls from any angle at high altitudes. Fixed models lack this flexibility, making the rotating JS800RT essential for complex high-reach dismantling.
Q: Will warranty be shortened under 24h operation for these demolition steel shears?
A: Full 12-month warranty for 8-hour single shift. Daily work over 8 hours halves warranty for these demolition steel 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.
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 mega-excavators fit the excavator hydraulic shear attachment directly, refit kits supplied for old machines. Motor & cylinder damage from self-modified oil circuits excluded.
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 shear be claimed?
A: Anti-rust coating applied before delivery of the scrap metal cutting shear. Rust from uncovered rain storage excluded.
Q: Standard idle storage steps for the scrap iron shear when unmounted?
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?
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.
Q: Exemption for the excavator shear attachment & motor 12-month 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?
A: Free warranty excavator shear parts, all freight & tariff borne by buyer. Overseas warehouse delivery is 3–7 days, sea 20–40 days, air for emergency 7–15 days.
Q: Can JS800RT be customized? Do you also supply a customized demolition pulverizer?
A: Custom jaw size & hydraulic parameters available for your oem excavator shear needs. As a comprehensive factory, we not only build giant shears but also supply customized demolition pulverizer solutions for mega-projects, ensuring you get the complete attachment package.
Q: Export order process for a scrap metal shear for sale?
A: MOQ 1 unit, bulk discount over 10 sets. T/T, L/C, Western Union accepted, 30% deposit before production. Process: confirm model → issue PI → inspection → shipment.
Q: Does export doc for this chinese scrap metal shear include Hardox certificate?

Q: Will sea transit rust be covered for the scrap metal shear excavator for sale?
A: Full anti-rust packing with desiccants for the scrap metal shear excavator for sale. Rust from post-delivery outdoor storage excluded.
Q: Full warranty claim process for the scrap metal shear machine?
A: 1. Provide serial number of the scrap metal shear machine, fault video & hour record; 2. Judge factory or man-made damage; 3. Free spare parts & video guide; 4. 200 RMB welding reimbursement within 6 months.
Q: Does mentioning Sany CAT mean official cooperation for this excavator metal shear?
A: Brands only show JS800RT compatibility as an excavator metal shear, no authorization or endorsement, no trademark infringement.
