III. Application Scenarios

(I) Application of 360° Stationary Rotating Swivel Boom

1. Outdoor Maintenance Scenario for Agricultural Machinery: In outdoor environments such as farmland and pastures, a pickup truck equipped with a 1000 lbs (450kg) boom lifts small and medium-sized components (such as gearbox housings and plowshare accessories) of tractors and harvesters. The 360° rotation function covers the maintenance area without moving the vehicle, and the 930-1295mm lifting radius is compatible with component disassembly/installation positions, avoiding injuries caused by manual handling of heavy components and improving maintenance efficiency.
2. Outdoor Cargo Transfer Scenario: In logistics transfer stations, construction sites, and other places, the 2000 lbs (900kg) boom is used for cargo transfer between pickup trucks and trucks (such as construction steel pipes and small equipment). The maximum lifting height of 2015mm can easily lift cargo from the ground to the pickup truck bed or unload it from the bed to the truck. The 360° rotation reduces the number of vehicle adjustments, making it particularly suitable for operations in narrow spaces.
3. Emergency Rescue Scenario: In road rescue, the 1000 lbs (450kg) boom can assist in lifting tires and chassis components (such as drive shafts) of faulty vehicles, eliminating the need to call large cranes and reducing rescue costs. Its lightweight design allows pickup trucks to quickly reach remote rescue sites such as rural areas and mountainous regions, improving emergency response speed.

(II) Application of Foldable Engine Crane

1. Engine Disassembly and Assembly Scenario in Auto Repair Shops: Repair shops use hydraulic cranes to disassemble/install engines (weighing 500-1000kg) of cars and light trucks. The hydraulic pump easily controls the lifting and lowering of the boom, and the 4 load gears accurately match the engine weight. The 1500mm frame height allows the engine to be lifted out of the engine compartment and directly moved to the maintenance platform, avoiding collisions caused by manual handling and improving maintenance accuracy.
2. Heavy Component Maintenance Scenario in Agricultural Machinery Stations: Agricultural machinery stations use standard cranes to handle tractor engines and harvester gearboxes (weighing 800-1000kg). The 1470mm frame height is compatible with the tall body of agricultural machinery, and the 978mm frame width can stably support components. The folding design allows the equipment to be stored in a corner when not in use, saving space in the maintenance workshop.
3. Equipment Handling Scenario in Factories: Factories use hydraulic cranes to move small machine tools and motors (weighing 300-750kg). The wheel set design allows the equipment to move flexibly in the workshop, and hydraulic drive eliminates the need for multi-person collaboration — a single person can complete the transfer of components from the warehouse to the production line. The 4 load gears are compatible with equipment of different weights, avoiding the risk of overloading.

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?
   • First, check if the rotating joint is blocked by impurities: Turn off the equipment, clean the dust and oil on the joint with a brush, apply lithium-based grease (2-3mm thick), and push the boom repeatedly to test the smoothness of rotation.
   • If jamming persists, check if the joint bearing is worn: Remove the rotating joint cover, check if the bearing balls are rusted or damaged. If so, replace the bearing with the same model (it is recommended to contact the manufacturer for original accessories) to avoid reduced rotation accuracy caused by self-modification.
2. The Base Becomes Loose After Installation, and There Is a Risk of Vehicle Shaking During Lifting. How to Handle It?
   • Confirm if the base bolts are tightened to the standard torque: Use a torque wrench to re-tighten the base bolts to a standard torque of 40-45N·m, tightening them one by one in a diagonal order to avoid uneven stress on the bolts.
   • Check if the fixed points of the pickup truck bed are firm: If the truck bed steel plate is thin (<3mm), place a 5mm thick steel plate between the base and the truck bed to increase the stress area and prevent the base from loosening due to truck bed deformation.

(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 the hydraulic oil level: Open the hydraulic oil tank cover. If the oil level is below the minimum scale line, add 46# anti-wear hydraulic oil to the normal level. Insufficient oil level will prevent the pump from building pressure.
   • Inspect if the hydraulic pipeline is leaking air: Turn off the equipment, check the connecting pipeline between the hydraulic pump and the oil cylinder. If the joint is loose, tighten it with a wrench (torque: 15-20N·m). If the seal ring is aged, replace it with a nitrile rubber seal ring to avoid pressure leakage.
2. The Equipment Still Occupies a Large Space When Stored After Folding. How to Optimize Storage?
   • The hydraulic model can be stored in disassembled parts: Separate the boom from the main frame. The 16kg small components can be stored in a tool cabinet, and the 55kg main frame can be folded and placed against the wall, using vertical space to reduce the floor area.
   • Adjust the folding angle of the standard model: Ensure the frame is fully folded, lower the boom to the lowest position, and fix the frame and boom with a strap to avoid shaking. Meanwhile, choose idle spaces such as workshop corners or under shelves for storage to improve space utilization.
3. The Crane Wheel Set Slides During Lifting, Affecting Operational Safety. What Is the Reason?
   • Check the ground conditions: If the ground is smooth (such as tile floors) or oily, place rubber anti-slip pads under the wheel set to increase friction. If the ground is uneven, adjust the wheel set height (some models have adjustable wheel sets) to ensure the equipment is stable.
   • Confirm if the lifting center of gravity is centered: If the component's center of gravity is offset, causing excessive stress on one side of the equipment, re-adjust the position of the lifting rope to align the component's center of gravity with the crane's center, avoiding wheel set sliding due to uneven stress.
