III. Application Scenarios

(I) 360° Stationary Rotating Swivel Boom Vehicle-Mounted Crane

1. Logistics and Freight Field: In short-distance transportation between urban and rural areas, pick-up trucks often need to load and unload small to medium-sized goods (such as home appliances, building materials, agricultural product boxes, etc.). This crane can quickly lift goods from the ground to the carriage or unload them from the carriage to the designated position. It is particularly suitable for logistics stations, rural cooperatives and other scenarios without large-scale loading and unloading equipment. The 360° rotation function can reduce the trouble of frequent truck parking position adjustment.
2. Outdoor Operation Scenarios: During road maintenance and power emergency repairs, workers need to carry tools and equipment (such as small generators, maintenance tool boxes, etc.). This crane can assist in loading and unloading these devices. With a minimum lifting radius of 930mm, it can accurately lift at positions close to the operation point, improving work efficiency.
3. Small Business Transportation: For small businesses such as hardware stores and furniture stores, if pick-up trucks are used to deliver goods and the customer's location has no loading and unloading conditions, this crane can be used as a temporary loading and unloading tool. The 450kg version is suitable for delivering furniture accessories and small hardware parts, while the 900kg version can handle the loading and unloading of small furniture (such as single sofas, bedside tables).

(II) Foldable Engine Crane

1. Automotive Repair Shops: When repairing a car engine, it is necessary to disassemble the engine from the car body, transport it to the repair bench, or install it back into the car body after repair. The multi-gear lifting function of this crane can be adapted to the weights of different models of engines (for example, the engine of a small car is about 200-300kg, and the engine of an SUV is about 300-500kg), accurately controlling the lifting force to avoid damage to the engine.
2. Construction Machinery Maintenance: In the maintenance of engines of small construction machinery (such as small excavators, loaders), the 1000kg load capacity can meet the handling needs of most small construction machinery engines. The foldable design allows the equipment to move flexibly in the repair workshop, adapting to the space requirements of different maintenance workstations.
3. Equipment Production Workshops: In engine production and assembly workshops, this crane can be used for the process transfer of engines, moving the engine from one production link to the next, such as from the part assembly area to the inspection area. Its stable lifting performance can ensure the smooth progress of the production process and reduce the cost and safety risks of manual handling.

IV. Frequently Asked Questions (FAQs)

(I) Operation and Use

1. Q: What safety precautions should be taken when the 360° vehicle-mounted crane is rotating for lifting?
   A: Firstly, ensure that the crane base is firmly fixed to the pick-up truck without looseness. Secondly, observe the surrounding environment during rotation to avoid touching obstacles or personnel, and keep the lifting speed uniform without being too fast. Finally, do not exceed the maximum load capacity marked on the equipment (450kg or 900kg) to prevent equipment damage or safety accidents caused by overloading.
2. Q: How to switch the 4 lifting gears of the foldable engine crane? Do I need to stop the machine when switching?
   A: Before switching the lifting gear, you must first stop the machine and ensure that the crane is in a no-load state (i.e., no items are being lifted). Locate the gear adjustment device (usually located at the connection of the lifting arm), pull out the gear pin according to the instructions in the manual, adjust to the target gear, reinsert the gear pin and confirm it is locked, then start the equipment for lifting operation. Do not switch gears under load.

(II) Installation and Maintenance

1. Q: When installing the 360° vehicle-mounted crane on a pick-up truck, are there any requirements for the installation position on the pick-up truck?
   A: Yes, there are clear requirements. It should be installed in the load-bearing area of the pick-up truck's rear bucket (usually, the pick-up truck is marked with the load-bearing position of the rear bucket at the factory, generally near the root of the carriage and away from the edge of the rear bucket) to avoid installing it in non-load-bearing areas, which may cause deformation of the carriage. At the same time, after installation, it should be fastened with special fixing bolts. It is recommended to check the tightness of the bolts regularly (e.g., every 10 uses) to ensure firm installation.
2. Q: What maintenance checks are required before using the foldable engine crane again after long-term storage?
   A: Firstly, check the hydraulic system, observe whether the hydraulic oil is sufficient and whether there is leakage. If the hydraulic oil is insufficient, replenish it to the specified level; if there is leakage, repair the sealing parts first. Secondly, check the pins and bearings at the folding joints, apply lubricating oil to ensure smooth folding and unfolding. Finally, test the lifting function, operate each gear under no-load condition, observe whether the lifting arm can lift and rotate normally, and confirm that there is no abnormality before using it under load.

(III) Transportation and Storage

1. Q: For the split packaging of the 360° vehicle-mounted crane, do they need to be transported separately during transportation? Can they be stacked?
   A: It is recommended to transport them separately to avoid package damage due to concentrated weight. If stacking is necessary, place the heavier packages (such as the 36KG large package) at the bottom and the lighter packages (such as the 13KG or 14KG small package) on top. The stacking height should not exceed 2 layers. At the same time, place a buffer material (such as foam board) between the two layers of packages to prevent collision damage caused by transportation jolts.
2. Q: Are there any requirements for the storage environment when the foldable engine crane is stored after folding?
   A: The storage environment should be dry and ventilated to avoid rusting of the equipment (especially the hydraulic system and metal connectors) in a humid environment. At the same time, the storage floor should be flat to avoid placing the equipment at an angle. If stored for a long time (more than 3 months), it is recommended to apply anti-rust oil on the metal surface and cover the equipment with a dust cloth to prevent dust from entering the hydraulic system or moving parts, which may affect subsequent use.
