Q: How to confirm the hydraulic eagle shear matches my excavator perfectly as an excavator scrap shear?
A: JISAN holds a full hydraulic database for Sany, XCMG, CAT, Komatsu and all mainstream brands. Our technical team will match the JS280RT or JS450RT hydraulic shear for excavator according to your 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 ultra-fast cycle of this scrap shearing machine bring to scrap yards?
A: Ordinary scrap metal shears take over 3.5s per cycle. JS280RT & JS450RT eagle shears are equipped with patented energy recovery speed valve, only 2.4s per cut. Daily output of this scrap shear 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 material bring? What material are the scrap shear blades?
A: Shell and upper bracket of JS280RT & JS450RT adopt genuine SSAB Hardox450 wear-resistant steel. The scrap shears 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, official SSAB certificates are delivered for customs. Other grabs, compactors and pulverizer shells use domestic NM400 wear steel, only pulverizer teeth adopt Hardox450.
Q: What full warranty & after-sales policies are available for overseas buyers looking for a scrap shear for sale?
A: As leading hydraulic scrap shear manufacturers, we offer 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 hydraulic scrap shear unit passes 48 lab tests. Warranty only covers factory defects, no compensation for downtime & injuries.
Q: How to choose the right excavator shear attachment between JS280RT and JS450RT? What’s the overload risk?
A: JS280RT fits 20–28T excavators, max force 2000kN, cuts 16mm plate & 360# H-beam;
JS450RT fits 30–50T excavators, max force 4150kN, cuts 30mm plate & 420# heavy I-beam;
Both Hardox450 shell & alloy steel blades. Oversized excavator shear on small excavator causes shell tear & permanent hydraulic damage, voiding warranty.
Q: Service life & reusability of alloy steel scrap metal shear blades? Warranty rule for these excavator shear parts?
A: Double-sided alloy steel blades (essential excavator shear parts) can be flipped for 3000–5000 hours under normal scrap work. Only 1-month warranty for the scrap shear blade: free replacement for breakage & chunk peeling within 1 month. Uniform wear & edge curling are normal consumable loss, bulk excavator shear parts and blades available.
Q: Core gap between cheap shears and JISAN JS280RT / JS450RT as a premium china excavator shear?
A: When comparing scrap metal shears made in china, low-cost carbon steel frames with partial thin wear plates crack quickly. JS280RT & JS450RT adopt integrated Hardox450 steel plus alloy blades with SSAB certificates. Cracked plates replaced free within 12 months. Other grabs & pulverizer shells use NM400 wear steel.
Q: Warranty repair rule for cracked Hardox450 shell plates on the metal shear for excavator?
A: Free component replacement for original crack within 12 months on the metal shear for excavator. 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 eagle shears cut concrete & rock? Should I use hydraulic demolition shears instead?
A: Only exposed rebar can be cut. Solid concrete & rock are prohibited to avoid fast blade wear on the demolition shears excavator setup. Steel rails & pressure vessels cannot be cut. Blade & shell damage from illegal operation fully void warranty. Use hydraulic demolition shears or pulverizer for rock demolition.
Q: How to choose between a scrap metal rotary shear and a fixed model? Are warranty terms identical?
A: Rotating model functions as a scrap metal rotary shear for indoor dismantling, fixed for open scrap yard with lower cost. Both Hardox450 shell & alloy steel blades with identical warranty. Rotating version 600–800kg heavier, slewing bearing 12-month warranty.
Q: Will warranty be shortened under 24h three-shift operation for a heavy scrap metal shear machine?
A: Full 12-month warranty for 8-hour single shift. Daily work over 8 hours halves the warranty for this heavy scrap metal shear machine. Custom thickened Hardox jaws recommended for non-stop 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 installation of the shear head for excavator be claimed?
A: New excavators fit the shear head for excavator directly, 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 a power shear or excavator shear setup?
A: Grease every 4 hours under heavy load for your power shear or excavator shear 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℃ for the scrap shear with excavator for sale, 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.
