I. Product Specifications

II. Product Details

Core Advantages

1. Omnidirectional Rotation for Flexible Operation: The boom supports 360° stationary rotation, covering the operation area within a 1295mm radius around the pickup without frequent vehicle movement. It is especially suitable for narrow outdoor spaces (such as farmland and rural roads), avoiding time loss caused by vehicle adjustment and improving operation efficiency by 40%.
2. Two Load Capacity Levels for Wide Scenario Adaptation: The 450kg model focuses on "light to medium-duty operations", capable of lifting agricultural machinery parts (e.g., plows, small gearboxes) and outdoor tools (e.g., generators, water pumps); the 900kg model focuses on "heavy-duty operations", meeting common heavy-duty needs of pickups (e.g., small engines, bundles of construction steel pipes). Both models cover most outdoor lifting scenarios.
3. Stable Installation for Safety and Reliability: The 270mm×270mm square base is fixed to the pickup truck bed via 4 sets of high-strength bolts. After installation, the fitting degree between the base and the truck bed reaches 95%, with no base displacement under a 500kg load; 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, adapting to outdoor rain and dust erosion.
4. Lightweight Design for Portability: The total weight of both models is controlled within 50kg (approximately 49kg for the 450kg model and 50kg for the 900kg model). Two people can complete the entire process from unpacking to installation. The component packaging is small (maximum package size: 113×32×18cm), which can be easily accommodated in the pickup truck bed without affecting the transportation of other cargo.

Detailed Design

• Rotating Joint: Equipped with a double-row radial ball bearing, the 360° rotation resistance is ≤50N, ensuring light and smooth operation. It is also equipped with a rubber sealing ring to prevent dust and rain from entering the joint, extending the bearing life.
• Safety Protection: A limit baffle is installed at the end of the boom to prevent accidental cargo slipping during lifting; anti-slip washers are reserved in the base mounting holes to enhance friction between bolts and the truck bed, preventing bolt loosening caused by long-term operation.
• Versatility: Multiple sets of adjustment holes are reserved in the base, compatible with the longitudinal beam spacing of pickup trucks from mainstream brands such as Ford, Toyota, and Great Wall. No additional customized mounting brackets are required, and it can be adapted immediately after unpacking.

III. Application Scenarios

1. Outdoor Maintenance Scenario for Agricultural Machinery: In farmland and pastures, a pickup equipped with the 450kg model boom lifts tractor gearboxes (approximately 300kg) and harvester cutter assemblies (approximately 400kg). The 360° rotation function allows alignment with maintenance points without moving the vehicle, the 930mm minimum lifting radius enables close-range component disassembly, and the 2015mm maximum height can lift components into the pickup truck bed, avoiding component damage or personnel strain caused by manual handling. It is especially suitable for remote areas without fixed maintenance equipment.
2. Small Cargo Transfer Scenario at Construction Sites: At construction and decoration sites, the 900kg model boom is used to transfer steel pipes (approximately 800kg per bundle) and cement boards (approximately 600kg per piece). The 1295mm maximum lifting radius can directly lift cargo from the ground to the pickup truck bed or unload it from the bed to the construction platform, eliminating the need for large cranes and reducing construction costs; the 1355mm height after folding does not occupy much space in the truck bed, allowing simultaneous loading of other decoration tools.
3. Outdoor Emergency Rescue Scenario: In rural road rescue, the 450kg model boom assists in replacing tires of faulty trucks (approximately 150kg) and lifting chassis components of trapped vehicles (e.g., drive shafts, approximately 200kg). Pickups can quickly reach narrow roads where cranes are difficult to access, and 360° rotation can adapt to rescue needs from multiple angles. The 13kg lightweight component design facilitates manual handling and assembly without mechanical assistance, improving rescue efficiency.
4. Equipment Handling Scenario in Livestock Farms: In large-scale livestock farms, the 900kg model boom lifts feed mixers (approximately 700kg) and water troughs (approximately 500kg). The 1800mm maximum lifting height can lift equipment to the second-floor platform of the farm, and the 270mm×270mm stable base can remain stable even on uneven ground, avoiding equipment dumping and pollution of the breeding environment during handling.

IV. Frequently Asked Questions (FAQs)

(I) What to Do If the Boom Gets Stuck Significantly During Rotation or Even Fails to Rotate?

1. Clean and Lubricate the Rotating Joint: First, stop the operation, use a high-pressure air gun to blow off impurities such as dust and hay at the joint, then wipe the oil on the joint surface with a rag dipped in diesel; then apply lithium-based grease (Model: 3#) into the bearing gap, with the amount enough to cover the bearing balls. Rotate the boom repeatedly 5-10 times to ensure uniform distribution of the grease, which usually solves minor jamming.
2. Check for Bearing Damage: If jamming persists after lubrication, remove the end cover of the rotating joint and check if the bearing balls are rusted, chipped, or if the cage is broken. If any of the above conditions occur, replace the double-row radial ball bearing with the same model (recommended specification: inner diameter 20mm, outer diameter 47mm, thickness 14mm). After replacement, reapply grease and install the end cover.
3. Inspect for Boom Deformation: If there has been overloaded operation or collision recently, check if the boom is bent or deformed (visually compare whether both sides of the boom are symmetrical). If slightly deformed, it can be corrected by slowly lifting a 300kg load and fine-tuning the boom in the opposite direction; if severely deformed, contact the manufacturer to replace the boom to avoid breakage caused by forced use.

(II) There Is a Gap Between the Base and the Pickup Truck Bed After Installation, and the Base Shakes During Lifting. How to Handle It?

1. Adjust the Bolt Tightening Sequence and Torque: First, loosen all base bolts, then retighten them in a "diagonal order" (e.g., first tighten the upper left corner → lower right corner → upper right corner → lower left corner). Tighten each bolt in 2-3 increments, with the final torque controlled at 40-45N·m (detectable with a torque wrench) to ensure the base fits the truck bed evenly and eliminate gaps.
2. Add Anti-Slip Washers: If there is a gap due to uneven surface of the truck bed longitudinal beam, place a 3mm thick rubber anti-slip washer (to be cut into a 270mm×270mm square with bolt holes reserved) between the base and the truck bed. Use the elasticity of rubber to fill the gap and enhance friction to prevent base shaking.
3. Check If the Base Mounting Holes Are Aligned: If the deviation between the base mounting holes and the pickup truck bed longitudinal beam holes exceeds 5mm, it will cause uneven stress on the base and gaps. Use a drill (diameter 10mm) to slightly enlarge the holes to adjust the hole positions, ensuring bolts can pass vertically through the base and longitudinal beam, avoiding base warping caused by inclined bolts.

(III) The Boom Suddenly Locks During Lifting and Cannot Be Lifted or Lowered Further. What Is the Reason?

1. Check for Overloading: First, confirm whether the weight of the lifted cargo exceeds the rated capacity (450kg/900kg). If overloaded, immediately unload part of the weight (e.g., split the cargo). After the weight is below the rated capacity, press the overload reset button (usually a red circular button) on the boom to unlock it.
2. Inspect the Hydraulic System (If Hydraulically Driven): For hydraulically driven booms, check if the hydraulic oil level is below the minimum scale line (the oil tank usually has a transparent oil level window). If the oil level is insufficient, add 46# anti-wear hydraulic oil to the normal level; at the same time, check if there is leakage in the hydraulic pipeline (oil stains at the joints). If leaking, replace the sealing gasket and retighten the pipeline.
3. Confirm If the Limit Device Is Triggered: The boom is equipped with limit switches for the maximum lifting angle (usually 75°) and maximum lowering angle (usually -10°). If the operating angle exceeds the limit, locking will be triggered. At this time, operate the boom in the opposite direction (e.g., slightly lower if locked during lifting) to exit the limit range and resume normal operation.

(IV) After Long-Term Outdoor Use, Rust Appears on the Boom Surface. How to Treat and Prevent It?

1. Rust Removal Treatment: For minor surface rust, gently sand the rusted area with sandpaper (800 grit) until the metal surface is exposed, then clean the surface with a rag dipped in alcohol; for deep rust (with small pits formed), spray a rust remover (e.g., WD-40) on the rusted area, let it stand for 10 minutes, then clean the rust with a wire brush, and smooth the surface with sandpaper.
2. Anti-Rust Protection: After rust removal, evenly spray anti-rust paint (recommended: outdoor-specific acrylic anti-rust paint, matching the original paint color) on the boom surface, applying 2 coats with a 2-hour interval between coats to ensure a coating thickness of ≥50μm; after the paint is dry, apply a layer of industrial petroleum jelly to enhance the anti-rust effect.
3. Daily Prevention: After each outdoor operation, wipe the boom surface with a dry rag to remove rainwater and oil; when not in use for a long time, cover the folded boom with a waterproof tarpaulin to avoid direct exposure to rain and snow; check the anti-rust coating every 3 months and touch up the paint in case of damage to extend the equipment service life.
