II. Product Details

Core Highlights

1. Sturdy Structure & Reliable Load-Bearing: Adopting all-steel construction and a precision-cast body, the overall structure has high strength. The 500-1000LB multi-gear load-bearing design can accurately match goods of different weights — the 500LB gear is suitable for lifting small agricultural machinery parts (e.g., 200kg plows) and outdoor tools (e.g., 150kg generators); the 750LB gear can handle medium-sized equipment (e.g., 300kg gearboxes); the 1000LB gear can carry heavy goods (e.g., 400kg small engines), meeting the needs of most truck-mounted lifting scenarios.
2. Flexible Installation & Strong Adaptability: It directly fits 2-inch standard receiver hitches and can be installed at any position on both sides of the truck tailgate. No in-depth modifications such as welding or drilling on the truck are required, and the installation takes ≤20 minutes. The 2 adjustable support legs can be fine-tuned according to the ground flatness during lifting to ensure the equipment fits the ground. Even on slightly uneven outdoor ground, it can remain stable and prevent the equipment from tilting during lifting.
3. Easy Operation & High Work Efficiency: The hydraulic drive design greatly reduces the operating force. Compared with manual cranes, a single person can easily control the lifting, extension, and retraction of the boom. The 360-degree rotation function allows the boom to cover the operation area within a 1310mm radius without moving the truck, which is especially suitable for narrow spaces (e.g., rural roads, construction site corners). It reduces the number of vehicle adjustments and improves work efficiency by more than 30%. The 1-inch hook with a safety latch can firmly fix goods to prevent slipping during lifting, enhancing operational safety.
4. Thoughtful Details & Good Durability: The hook is equipped with a safety latch, which automatically locks after the goods are hooked and can only be removed by manual unlocking, preventing goods from falling due to jolting or accidental contact. The all-steel body surface undergoes anti-rust spray treatment, with a salt spray test of 48 hours, which can resist outdoor rain and dust erosion and extend the service life of the equipment. The chain is made of high-strength alloy material, which has better load-bearing capacity and wear resistance than ordinary chains, reducing the frequency of daily maintenance.

III. Application Scenarios

1. Outdoor Maintenance Scenario for Agricultural Machinery: In outdoor environments such as farmland and pastures, trucks equipped with this crane can lift tractor gearboxes (approximately 300kg) and harvester cutter assemblies (approximately 350kg) in the 500-750LB gear. The 360-degree rotation function allows alignment with maintenance points without moving the truck, and the 1010mm retracted radius is suitable for close-range component disassembly. The maximum hook height of 2010mm can lift components into the truck bed, avoiding component damage or personnel strain caused by manual handling. It is particularly useful in remote areas without fixed maintenance equipment.
2. Small-Scale Cargo Transportation Scenario at Construction Sites: At construction sites for building decoration and road construction, the 1000LB gear can be used to transport construction steel pipes (approximately 400kg per bundle) and precast cement boards (approximately 350kg per piece). The 1310mm extended radius can directly lift goods from the ground to the truck bed or unload them from the bed to the construction platform, eliminating the need for large cranes and reducing construction costs. The 2 adjustable support legs can stably support the equipment on uneven construction site ground, preventing tipping and ensuring operational safety.
3. Outdoor Emergency Rescue Scenario: In vehicle rescue on rural roads and mountain highways, the 500-750LB gear can assist in replacing tires of faulty trucks (approximately 150kg) and lifting chassis components of trapped vehicles (e.g., drive shafts, approximately 200kg). Trucks can quickly reach narrow roads where cranes are difficult to access. The hydraulic drive operation is convenient, and a single person can complete the rescue operation, reducing the time spent waiting for large rescue equipment and improving emergency response efficiency.
4. Equipment Handling Scenario in Livestock Farms: In large-scale livestock and poultry farms, the 750-1000LB gear can be used to lift feed mixers (approximately 350kg) and water troughs (approximately 300kg). The maximum hook height of 2010mm can lift equipment to the second-floor platform of the farm, and the 360-degree rotation can flexibly adjust the placement position of the equipment, avoiding collision with breeding facilities during equipment handling and reducing interference with the breeding environment.

IV. Frequently Asked Questions (FAQs)

(I) What to Do If the Boom Lifts or Lowers Slowly or Even Fails to Operate Normally During Lifting?

1. Check Hydraulic Oil Level and Quality: First, turn off the equipment power (for electric hydraulic models), open the hydraulic oil tank cap, and check if the oil level is below the minimum scale line. If the oil level is insufficient, add 46# anti-wear hydraulic oil to the normal level; if the hydraulic oil is turbid and contains impurities, completely replace it with new oil to prevent impurities from clogging the hydraulic pipeline or damaging the pump body.
2. Inspect for Hydraulic Pipeline Leaks: Check the connecting pipeline between the hydraulic pump and the oil cylinder, and see if there are oil stains at the joints. If a leak is found, first close the hydraulic valve, loosen the joint and replace the aged sealing gasket, then reinstall and tighten it with a wrench to a torque of 15-20N·m to prevent further leakage.
3. Verify the Working Status of the Hydraulic Pump: If the oil level and pipeline are normal, start the hydraulic pump (or manually operate the hydraulic lever) and listen for abnormal noises from the pump body. If the pump body has no response or makes excessive noise, it may be a pump failure. Contact the manufacturer for repair or replacement of the hydraulic pump; do not disassemble it by yourself.

(II) After Installation, the Equipment Does Not Fit Tightly with the Truck Hitch, and Shakes Significantly During Lifting. How to Handle It?

1. Check the Compatibility Between the Hitch and the Installation Base: Confirm whether the truck hitch is a 2-inch standard model. If the hitch is worn or has a size deviation, it will cause poor fitting. A 1-2mm thick metal gasket can be placed between the base and the hitch to fill the gap and enhance the fitting degree.
2. Tighten the Installation Bolts: Use a torque wrench to retighten the bolts connecting the equipment and the hitch. The standard torque is 30-35N·m, and tighten them in diagonal order in batches to avoid uneven stress on the bolts leading to equipment shaking.
3. Adjust the Height of the Support Legs: Before lifting, deploy the 2 adjustable support legs and fine-tune their length according to the ground flatness to ensure the bottom of the support legs is fully in contact with the ground and bears force evenly. The support legs share part of the lifting pressure, reducing the equipment's reliance on the hitch and minimizing the shaking amplitude.

(III) The Hook's Safety Latch Cannot Close or Unlock Normally, Affecting Goods Hooking. What to Do?

1. Clean Impurities in the Latch: Use a high-pressure air gun to blow off dust, rust, and other impurities in the gaps of the safety latch, then wipe the moving parts of the latch with a rag dipped in diesel to remove oil stains and dirt, ensuring the latch can rotate flexibly.
2. Lubricate the Latch Components: Apply a small amount of lithium-based grease (Grade 3) to the hinges and springs of the latch, and push the latch repeatedly 5-10 times to distribute the grease evenly, reducing friction between components and restoring the opening and closing flexibility of the latch.
3. Check the Structural Integrity of the Latch: If it still cannot be used normally after cleaning and lubrication, check whether the latch is deformed or the spring is broken. If the spring is broken, replace it with a spring of the same specification (diameter 1.5mm, length 30mm); if the latch is deformed, contact the manufacturer to replace the hook to avoid safety hazards caused by using damaged components.

(IV) During Lifting, the Equipment Suddenly Tilts and Risks Tipping. How to Handle It Emergently?

1. Stop Lifting Operations Immediately: Quickly turn off the hydraulic pump (or stop manual pressure application), and prohibit further lifting, lowering, or rotating of the boom to prevent the tilt from worsening.
2. Adjust the Center of Gravity of the Goods: If the tilt is caused by the offset of the goods' center of gravity, under the premise of ensuring safety, slowly fine-tune the rotation angle or extension/retraction length of the boom to move the goods' center of gravity directly above the center of the equipment, reducing the force on one side.
3. Reinforce Support or Unload Goods: If the support legs sink due to soft ground, place a steel plate (thickness ≥5mm, area ≥200×200mm) under the bottom of the support legs to increase the force-bearing area; if the tipping risk is high, slowly lower the goods to the ground, unload them, then check the status of the equipment and support legs, and re-lift after troubleshooting.
