(I) 360° Stationary Rotating Swivel Boom

1. Dual Advantages of Flexibility and Load-Bearing: The 1000LBS (450kg) model focuses on light-to-medium operations, capable of lifting agricultural machinery parts (e.g., 200kg plows) and outdoor tools (e.g., 150kg generators); the 2000LBS (900kg) model focuses on heavy-duty needs, handling bundles of construction steel pipes (800kg) and large feed mixers (700kg), covering most outdoor lifting scenarios for pickups.
2. Balance Between Stability and Portability: The 270mm×270mm square base is fixed to the truck bed via 4 sets of high-strength bolts, with no displacement under a 500kg load; the total weight is ≤50kg, allowing two people to complete installation within 30 minutes. The component packaging is compact, without affecting the pickup's daily cargo transportation.
3. Durability and Universal Adaptability: The boom is welded with Q345 high-strength steel, and its surface undergoes phosphating + anti-rust spray treatment, with a salt spray test of 48 hours, resisting outdoor rain and dust erosion; multiple sets of adjustment holes are reserved in the base, compatible with mainstream pickups such as Ford, Toyota, and Great Wall. No customized brackets are required, and it can be installed immediately after unpacking.

1. Hydraulic Model: Labor-Saving and Efficient: The operating force of the single-piston hydraulic pump is only 1/3 of that of the standard model. The 4 load gears can accurately match lifting needs from small motors (300kg) to 1-ton engines. The 1500mm frame height can easily lift components to the maintenance platform, avoiding damage caused by manual handling.
2. Standard Model: Stable and Reliable: With a 1470mm high frame + 978mm wide base, it can operate stably on both workshop concrete floors and outdoor dirt roads. Its weight of 76kg makes it suitable for fixed workstations; the plywood case packaging has high strength, protecting the equipment from collisions during long-distance transportation.
3. Space-Saving Folding Design: The volume of the hydraulic model is reduced by 60% after folding, and the standard model can further compress storage space by disassembling wheel sets. It is particularly suitable for scenarios with limited space such as repair shops and agricultural machinery stations, and can be stored in corners when not in use, without occupying core operation areas.

III. Application Scenarios

(I) Application of 360° Stationary Rotating Swivel Boom

1. Outdoor Maintenance Scenario for Agricultural Machinery: In farmland, a pickup equipped with a 1000LBS (450kg) boom disassembles tractor gearboxes (approximately 350kg) and lifts harvester cutters (approximately 400kg). The 360° rotation allows alignment with maintenance points without moving the vehicle, and the 930mm minimum radius enables close-range operations, avoiding strains caused by manual handling. It is particularly useful in remote areas without fixed equipment.
2. Small-Scale Cargo Transportation Scenario at Construction Sites: At construction and decoration sites, the 2000LBS (900kg) boom transfers steel pipe bundles (approximately 800kg) and cement boards (approximately 600kg). The 1295mm maximum radius can lift cargo from the ground to the pickup truck bed or unload it to the second-floor construction platform, eliminating the need for large cranes and reducing construction costs; the folded height of 1355mm does not occupy much space in the truck bed, allowing simultaneous loading of tools.
3. Outdoor Emergency Rescue Scenario: In rural road rescue, the 1000LBS (450kg) boom assists in replacing tires of faulty trucks (approximately 150kg) and lifting drive shafts of trapped vehicles (approximately 200kg). Pickups can quickly reach narrow roads where cranes are difficult to access; the 360° rotation can adapt to rescue needs from multiple angles, and the lightweight components facilitate manual assembly, improving rescue efficiency.

(II) Application of Foldable Engine Crane

1. Engine Disassembly & Assembly Scenario in Auto Repair Shops: Repair shops use hydraulic cranes to disassemble car engines (approximately 400kg) in the 500kg gear and install light truck engines (approximately 800kg) in the 1000kg gear. Hydraulic drive enables smooth lifting and lowering, avoiding component collisions; the 4 load gears accurately match weights, preventing equipment damage due to overloading.
2. Heavy-Duty Maintenance Scenario in Agricultural Machinery Stations: Agricultural machinery stations use standard cranes to handle 800kg tractor engines and 600kg harvester gearboxes. The 1470mm frame height is compatible with the tall body of agricultural machinery, and the 978mm width stably supports components. It is folded for storage when not in use, saving workshop space.
3. Equipment Relocation Scenario in Factories: Factories use hydraulic cranes to move 300kg motors and 750kg small machine tools. The wheel sets are adapted to workshop floors, allowing one person to operate the hydraulic pump to complete lifting; the component packaging facilitates transfer between different production lines, improving equipment deployment efficiency.

IV. Frequently Asked Questions (FAQs)

(I) FAQs About 360° Stationary Rotating Swivel Boom

1. What to Do If the Boom Gets Stuck During Rotation and Cannot Turn Smoothly?
   • Clean and Lubricate: Use a high-pressure air gun to blow off dust from the rotating joint, wipe oil stains with a rag dipped in diesel, then apply Grade 3 lithium-based grease (covering the bearing balls) and rotate the boom repeatedly 5-10 times.
   • Check the Bearing: If jamming persists, remove the joint end cover and check if the bearing is rusted or chipped. If so, replace it with a double-row radial ball bearing (specification: inner diameter 20mm, outer diameter 47mm, thickness 14mm).
   • Inspect for Deformation: If overloaded or collided, visually check if the boom is symmetrical. Slight deformation can be corrected by lifting a 300kg load and fine-tuning in the opposite direction; for severe deformation, contact the manufacturer to replace the boom.
2. There Is a Gap Between the Base and the Truck Bed After Installation, and the Base Shakes During Lifting. How to Handle It?
   • Tighten Diagonally: Loosen the bolts, then retighten them in the order of "top-left → bottom-right → top-right → bottom-left" in 2-3 increments, with a torque of 40-45N·m, ensuring the base fits the truck bed.
   • Add Washers: For uneven truck bed longitudinal beams, place a 3mm thick rubber anti-slip washer (270mm×270mm with bolt holes reserved) between the base and the bed to fill the gap and enhance friction.
   • Adjust Hole Positions: If the deviation between the base holes and the truck bed holes exceeds 5mm, slightly enlarge the holes with a 10mm drill to ensure bolts pass vertically, avoiding base warping caused by inclined bolts.

(II) FAQs About Foldable Engine Crane

1. The Boom of the Hydraulic Crane Cannot Lift or Lower, and the Hydraulic Pump Has No Pressure Output. What to Do?
   • Check Oil Level: Open the oil tank cover; if the oil level is below the scale line, add 46# anti-wear hydraulic oil to the normal level.
   • Inspect for Leaks: Check hydraulic pipe joints; if there are oil stains, replace the sealing gasket and tighten (torque: 15-20N·m).
   • Reset the Valve: If the pressure relief valve is not closed, tighten it clockwise, then test the lifting function again.
2. The Wheel Set Gets Stuck During Crane Movement, and the Crane Deviates from the Route. What Is the Reason?
   • Clean the Axle: Use a brush to remove dust and impurities from the axle, apply lithium-based grease, and test if the wheel set rotates smoothly.
   • Check Tires: If the rubber tires are worn (tread depth <1mm) or deflated, replace them with tires of the same specification (recommended: diameter 150mm, width 50mm).
   • Adjust Wheelbase: For the hydraulic model, the front wheelbase is 800mm and the rear wheelbase is 540mm. If the axle is loose, tighten the axle bolts with a wrench (torque: 30-35N·m) to ensure the wheel set is parallel.
3. The Equipment Still Occupies a Large Space After Folding. How to Optimize Storage?
   • Disassemble the Hydraulic Model: Separate the boom from the main frame; store 16kg small components in a tool cabinet, and place the 55kg main frame vertically against the wall to utilize vertical space.
   • Compress the Standard Model: Disassemble wheel sets and auxiliary brackets, fold the frame, and secure it with straps. Store it under shelves or in workshop corners to reduce the floor area by 60%.
