Q: How do I confirm the JS150RT eagle-beak shear perfectly matches my 12-18 ton excavator?
A: JISAN maintains a full hydraulic database for CAT, Komatsu, Sany, Volvo, and all mainstream 12-18T midi excavators. Our engineers calibrate the JS150RT hydraulic shear for excavator to match your carrier's exact 250-300 bar working pressure and 150 L/min flow rate. This precise matching prevents host machine overheating and ensures maximum cutting force.
Q: What advantage does the differential acceleration valve bring to structural demolition?
A: Ordinary shears are slow, but the JS150RT eagle-beak shear utilizes a patented differential valve optimized for 150 L/min flow, increasing no-load stroke speed by nearly 50%. Unlike slow demolition crushers, these demolition shears slice through H-beams and rebar instantly, boosting daily steel processing output by over 30%.
Q: Is the 1350kg weight and Hardox450 body durable enough for heavy municipal work?
A: Absolutely. Weighing 1350kg, the JS150RT is the ultimate core workhorse. The shell and upper bracket adopt genuine SSAB Hardox450 wear-resistant steel. As a premium excavator shear attachment, it resists severe impact and deformation when processing thick structural steel, ensuring a significantly longer lifespan than cheap carbon-steel alternatives.
Q: What after-sales support and warranty do you provide for this mid-size shear?
A: We offer a global 10-30-824 rapid service (10-min reply, 30-min plan, 8-hour parts dispatch).
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, and bulk excavator shear parts are always in stock for rapid global shipping.
Q: How does it compare to a concrete pulverizer or concrete crusher for residential demolition?
A: For residential demolition involving reinforced concrete, the JS150RT power shear is used to cleanly slice through the exposed rebar and steel frames. A concrete pulverizer or crusher is strictly for crushing pure masonry and concrete blocks. Using a shear to crush solid concrete will dull the alloy blades; for pure concrete, you need a dedicated crusher attachment.
Q: What is the service life of the blades, and how do I maintain them?
A: The double-sided alloy steel blades on this scrap metal shear can be flipped and reused for 3,000–5,000 hours under normal scrap work. A 1-month warranty covers breakage and chunk peeling. Uniform wear is normal consumable loss. We recommend adjusting the blade clearance regularly to prevent thin rebar from jamming the jaws.
Q: What sets JISAN apart from cheap midi shear alternatives on the market?
A: Cheap 12-18T shears often use weak domestic steel that bends at the pivot points under high pressure. As a direct factory, JISAN uses integrated Hardox450 steel and one-piece forged alloy pivot pins, guaranteeing this excavator shear will not deform even under the maximum 300 bar hydraulic pressure of a heavy-duty midi carrier.
Q: What is the warranty policy for the Hardox450 shell plates?
A: Free component replacement is provided for original structural cracks within 12 months on the shear head for excavator. If a weld crack occurs within 6 months, we reimburse 200 RMB for local welding costs. Cracks caused by using the shear as a hammer, pry bar, or cutting beyond rated capacity are strictly excluded.
Q: Why choose the rotating model with a 593mm diameter over a fixed shear?
A: The JS150RT functions as a scrap metal rotary shear with a massive 593mm rotation diameter and 360° continuous rotation. This allows operators to grab irregular pipes, ship components, and steel beams from any angle in tight municipal spaces or scrap yards, a flexibility that fixed models completely lack.
Q: Will the warranty be shortened under 24-hour continuous operation?
A: The standard 12-month warranty assumes an 8-hour single shift. If your scrap yard runs this equipment on a 24-hour three-shift schedule, the warranty period is halved. We recommend strict 4-hour lubrication intervals and custom thickened Hardox jaws for non-stop heavy-duty operations.
Q: Can the hydraulic shear operate underwater in ship-breaking yards?
A: While used in ship-breaking, prolonged submersion of this hydraulic demolition shears setup is not recommended. If used in wet or muddy conditions, immediate full cleaning and greasing are required after each shift. Rust or jamming caused by poor maintenance in watery environments is excluded from warranty.
Q: Is damage from improper installation covered by warranty?
A: New 12-18T excavators can fit this attachment directly via forearm installation, while refit kits are supplied for older machines. Motor or cylinder damage resulting from self-modified oil circuits that cannot handle the required 150 L/min flow is excluded. Standard installation takes only 1–2 hours.
Q: Will insufficient lubrication void the warranty?
A: Yes. You must grease all pivot points and the slewing bearing every 4 hours under heavy load. Bearing and pin failures caused by insufficient lubrication are considered maintenance negligence and are not covered under warranty.
Q: What are the cold-weather operation guidelines?
A: When operating below 0°C, perform a 5–10 minute no-load warm-up before cutting to protect the seals and hydraulic motor. Use low-temperature hydraulic oil if temperatures drop below -10°C. Freeze cracks resulting from poor winter maintenance are excluded.
Q: Is surface rust from outdoor rain storage covered?
A: A heavy-duty anti-rust coating is applied before delivery of our scrap metal cutting shears. However, surface rust caused by prolonged outdoor storage in the rain without a protective cover is excluded from warranty.
Q: What is the standard storage procedure when the shear is unmounted?
A: Clean all metal slag, coat the Hardox shell with anti-rust oil, fully retract the cylinders, and wrap the unit in waterproof film if stored indoors. Outdoor storage without protection is not recommended for long-term idle periods.
Q: Are hydraulic leaks and slow movements covered under warranty?
A: Factory defects in the Finnish-imported piston motor, valves, and cylinders causing leaks or slow movements are covered for 12 months. Damage caused by self-adjusted pressure settings exceeding 300 bar or contaminated hydraulic oil is excluded.
Q: What voids the 12-month warranty on the slewing bearing and motor?
A: Tooth breakage on the slewing bearing due to insufficient greasing, or motor shaft breakage caused by hard impacts and unauthorized pressure tuning, will void the warranty for these specific components.
Q: What is the lead time for overseas spare parts delivery?
A: Warranty replacement parts are provided free of charge; the buyer bears all freight and tariff costs. Delivery takes 3–7 days from overseas warehouses, 20–40 days by sea, or 7–15 days via air freight for emergency downtime situations.
Q: Can the JS150RT be customized for OEM orders?
A: Yes. We can customize jaw sizes (larger than the standard 389mm opening) and hydraulic parameters to meet your OEM requirements. Custom frames still use Hardox450 steel, with a 7–15 day lead time after 3D drawing confirmation.
Q: What is the export process and payment terms?
A: The MOQ is 1 unit, with bulk discounts available for fleet orders of 10+ sets. We accept T/T, L/C, and Western Union (30% deposit before production). The process is: Confirm Model → Issue PI → Inspection → Shipment.
Q: Do export documents include the Hardox certificate?
A: Yes. Full export documentation includes the Commercial Invoice, B/L, CO, RCEP, CE certificate, official SSAB Hardox certificate, and factory inspection report for smooth global customs clearance.
Q: Is rust occurring during sea transit covered?
A: We use full anti-rust packing with desiccants for every 1350kg unit. Any minor surface oxidation occurring during long sea transit or post-delivery outdoor storage is considered normal and is excluded from warranty.
Q: What is the step-by-step warranty claim process?
A: 1. Provide the serial number, a fault video, and hour records. 2. Our engineers determine if the damage is a factory defect or man-made. 3. Free spare parts and video installation guides are provided for eligible claims. 4. Welding cost reimbursement (200 RMB) applies within 6 months.
Q: Does mentioning brands like CAT or Volvo imply official cooperation?
A: No. Brand names are mentioned solely to indicate the compatibility of the JS150RT eagle-beak shear with various 12-18 ton carrier models. It does not imply official authorization, endorsement, or trademark infringement by these manufacturers.
