II. Product Details

Core Highlights

1. Compliant and Reliable, Suitable for Cross-Border Scenarios: With CE certification, it meets EU and most countries' safety and environmental standards, applicable to foreign trade exports or operation scenarios with high compliance requirements (e.g., European construction sites, cross-border logistics warehouses), eliminating compliance risks in trade and use.
2. Flexible Size, Adaptable to Multiple Scenarios: The boom length is adjustable from 1060mm to 1360mm—short boom for operations in narrow spaces (e.g., warehouse corners, rural roads), long boom covering a 1.36-meter radius to reduce vehicle movement. The hook height ranges from 470mm to 2150mm, allowing lifting goods directly from the ground to truck beds (approx. 1.8-2 meters high) without additional heightening equipment, improving operational flexibility by 50%.
3. Stable, Durable, and Easy to Operate: The boom and base are made of Q235 high-strength steel, with no obvious deformation under 500KGS load. The surface undergoes phosphating anti-rust treatment, resisting outdoor rain and dust erosion to extend service life. Multiple sets of mounting holes are reserved on the base, adapting to mainstream models such as pickups and light trucks—no customized brackets required, and installation can be completed by 2-3 people within 1 hour, reducing labor costs.
4. Bulk Transportation-Friendly: Adopting "carton + pallet" packaging, with 5 units per pallet. The standardized pallet size adapts to forklift and container transportation, ensuring high logistics efficiency and low damage during bulk procurement, especially suitable for enterprise-level and cross-border bulk orders.

III. Application Scenarios

1. Outdoor Maintenance of Agricultural Machinery: In farmland and pastures, it is used to lift tractor gearboxes (approx. 300KGS) and harvester cutter assemblies (approx. 400KGS). The 1060mm short boom can operate close to the bottom of agricultural machinery, and the 470mm minimum hook height facilitates picking up parts near the ground. Maintenance can be completed without moving the vehicle, avoiding strains caused by manual handling—especially suitable for large-scale farms with compliance requirements.
2. Small-Scale Construction Site Cargo Transportation: In small construction sites such as building decoration and municipal maintenance, it transports cement boards (approx. 350KGS) and steel pipe bundles (approx. 450KGS). The 1360mm long boom can lift goods directly from the ground to engineering vehicle beds (approx. 1.8 meters high), and the 2150mm maximum hook height meets the unloading needs of temporarily built second-floor construction platforms. No large cranes are required, reducing construction costs, and CE certification meets construction site safety compliance requirements.
3. Warehouse Logistics Loading/Unloading: In warehouses and logistics stations, it assists in loading/unloading small and medium-sized goods (e.g., 300KGS home appliance packaging boxes, 400KGS industrial parts boxes). The 950mm wide base ensures stable operation on warehouse floors, and the 800mm inside width adapts to standard palletized goods. Cooperating with forklifts for pallet handling, it realizes efficient connection of "lifting + handling", improving warehouse loading/unloading efficiency.
4. Outdoor Emergency Support: In rural road and scenic area rescue, it lifts faulty vehicle tires (approx. 150KGS) and small rescue equipment (e.g., 200KGS water pumps). With a net weight of 80KGS, 2-3 people can carry it to narrow areas inaccessible to cranes. The 1060-1360mm boom flexibly adjusts the operation angle to quickly complete rescue support, and CE certification ensures the safety and compliance of rescue equipment.

IV. Frequently Asked Questions (FAQs)

1. What to Do If the Boom Gets Stuck During Adjustment and Cannot Extend/Retract or Fix Smoothly?
   • Clean and Lubricate: First, use a high-pressure air gun to blow off dust and sand in the boom adjustment rail, then wipe oil stains on the rail surface with a rag dipped in diesel. Then apply Grade 3 lithium-based grease to the contact area between the rail and slider, push and pull the boom repeatedly 3-5 times to ensure even lubrication and relieve jamming.
   • Check the Locating Pin: If jamming is accompanied by "stuck noise", check if the boom locating pin is aligned with the adjustment hole. If misaligned, loosen the locating pin bolt, realign with the hole, and tighten to ensure the boom can be stably fixed at the specified length after extension/retraction.
   • Inspect for Deformation: Visually check if the boom is bent (compare symmetry on both sides). Slight deformation can be corrected by slowly adjusting the boom and fine-tuning manually; for severe deformation, contact the manufacturer to replace the boom—do not use it forcefully to avoid breakage.
2. After Installation, the Base Does Not Fit Tightly with the Vehicle and Shakes During Lifting. How to Handle It?
   • Tighten Bolts Diagonally: Loosen all base fixing bolts, then retighten them in 2 increments in the diagonal order of "top-left → bottom-right → top-right → bottom-left", with the final torque controlled at 45-50N·m (tested with a torque wrench) to ensure the base fits the vehicle mounting surface evenly and eliminate gaps.
   • Add Buffer Washers: If the vehicle mounting surface is uneven, place a 3mm thick rubber buffer washer (cut into a shape matching the base with bolt holes reserved) between the base and the vehicle. Use the elasticity of rubber to fill gaps, enhance friction, and reduce shaking.
   • Adjust Mounting Holes: If the deviation between the base holes and vehicle holes exceeds 5mm, slightly enlarge the holes with a 12mm diameter drill to ensure bolts pass vertically through the base and vehicle, avoiding uneven stress and shaking of the base caused by inclined bolts.
3. The Hook Cannot Stay Stably at the Specified Height and Slips Slowly. What to Do?
   • Check the Brake Device: For manual brakes, check if the brake lever is pulled to the locked position; if loose, re-pull and confirm the buckle is locked into the slot. For hydraulic brakes, check if the hydraulic brake valve is tightly closed—tighten the brake valve knob clockwise and test if the hook is stable.
   • Inspect the Hydraulic System (Hydraulic Models): Open the hydraulic oil tank cap and check if the oil level is below the minimum scale line; if insufficient, add 46# anti-wear hydraulic oil. At the same time, check hydraulic pipe joints—if there is oil leakage, replace the sealing gasket and tighten the joint to avoid pressure loss and slipping.
   • Replace Worn Parts: If brake pads or hydraulic seals are worn, contact the manufacturer to obtain replacement parts of the same model. After replacement, test the hook's braking effect and put it into use only after confirming no slipping risk.
4. After Bulk Transportation, Some Equipment Has Loose Booms and Cannot Bear Loads. What to Do?
   • Check Transportation Fixing Parts: Check if the boom fixing buckles in the equipment packaging fell off during transportation. If so, re-install the buckles and tighten the boom to avoid loose connections caused by boom displacement during handling.
   • Calibrate the Load-Bearing Structure: Loosen the connecting bolts between the boom and base, realign with the mounting holes, and retighten to ensure the boom is perpendicular to the base and bears force evenly. Then test the load capacity with a 200KGS standard weight, and conduct a 500KGS full-load test only after confirming no looseness.
   • Contact After-Sales for Inspection: If the load capacity is still insufficient after calibration, check for transportation collision marks (e.g., base deformation, boom weld cracks), keep photos of the marks, and contact the manufacturer's after-sales service. Apply for repair or replacement in accordance with the after-sales policy related to CE certification to ensure the equipment is compliant and usable.
