5. സജ്ജീകരണവും അസംബ്ലിയും

The YOUSHENG Folding Crane is designed for simple assembly. While specific step-by-step instructions are not provided, the general process involves:

1. അൺപാക്ക് ചെയ്യുന്നു: Carefully remove all components from the packaging. Verify all parts are present according to the packing list (not provided, but implied).
2. അടിസ്ഥാന അസംബ്ലി: Assemble the main base frame, ensuring all bolts are securely fastened. Attach the universal wheels to the designated points on the base.
3. Column and Boom Attachment: Mount the vertical column to the base. Attach the boom assembly to the column, ensuring the pivot points are correctly aligned and secured with pins or bolts.
4. Hydraulic Cylinder Installation: Install the hydraulic cylinder between the column and the boom, connecting it to the appropriate mounting points. Ensure the release valve is closed before attempting to operate.
5. പ്രാഥമിക പരിശോധന: After assembly, perform a thorough visual inspection to ensure all connections are tight and there are no loose parts.
6. പ്രവർത്തന പരിശോധന: Before lifting any load, perform a test lift with no load to familiarize yourself with the controls and ensure smooth operation of the hydraulic system.

The crane's folding mechanism allows for quick setup and breakdown. To unfold, extend the legs and boom until they lock into place. To fold, release the locking mechanisms and collapse the frame and boom.

6. പ്രവർത്തന നിർദ്ദേശങ്ങൾ

Follow these steps for safe and effective operation of your hydraulic crane:

1. ജോലിസ്ഥലം തയ്യാറാക്കുക: Ensure the area is clear of obstacles and personnel. Position the crane on a firm, level surface.
2. Extend the Boom: Adjust the 4-speed retractable boom to the desired length based on the weight of the load. Remember, a shorter boom provides greater lifting capacity. Secure the boom at the chosen setting.
3. Position the Crane: Roll the crane into position, ensuring the load is directly beneath the hook. Lock the wheels if applicable to prevent movement during lifting.
4. Attach the Load: Securely attach the load to the crane's hook using appropriate chains, slings, or lifting eyes. Ensure the load is balanced to prevent swinging.
5. Lift the Load: Close the hydraulic release valve. Operate the pump handle to slowly raise the boom and lift the load. Lift only high enough to clear obstacles.
6. Move the Load: With the load lifted, carefully maneuver the crane to the desired location. Avoid sudden movements.
7. Lower the Load: Once in position, slowly open the hydraulic release valve to lower the load. Control the descent to ensure a gentle placement.
8. Detach the Load: Once the load is safely on the ground and stable, detach it from the crane's hook.
9. പിൻവലിക്കുകയും സംഭരിക്കുകയും ചെയ്യുക: After use, retract the boom, close the hydraulic valve, and fold the crane for compact storage.
