To perform a pre-operational check, ensure all controls are functioning correctly, inspect hydraulic lines for leaks, check the hoist and hook for damage, and verify that all safety devices are operational.
Regular maintenance includes lubricating moving parts, checking hydraulic fluid levels, inspecting the electrical system, and ensuring all bolts and fasteners are secure.
If experiencing hydraulic issues, check for leaks, ensure the hydraulic fluid is at the correct level, inspect the pump and hoses for damage, and verify that the hydraulic pressure is within the recommended range.
Operators should wear appropriate personal protective equipment, ensure the crane is on stable ground, never exceed the crane's load capacity, and always be aware of the crane's surroundings to avoid accidents.
To adjust the boom length, ensure the crane is not under load, release the locking mechanism, extend or retract the boom to the desired length, and then secure the locking mechanism.
Common electrical problems include issues with the control panel, faulty wiring, and blown fuses. Solutions involve checking connections, replacing damaged wires, and ensuring fuses are intact.
Store the crane in a dry, sheltered area away from corrosive materials. Lower the boom to a safe position, engage all brakes, and disconnect the battery if the crane will be stored for an extended period.
To replace the hydraulic fluid, ensure the crane is on a level surface, remove the hydraulic reservoir cap, drain the old fluid, replace the filter if necessary, and refill with the recommended hydraulic fluid type.
The crane can be used in various weather conditions but should not be operated in extreme conditions such as heavy rain, high winds, or lightning storms to ensure safety and prevent equipment damage.
To calibrate the load indicator, follow the manufacturer's instructions to set the zero point, apply a known weight, adjust the indicator to match the weight, and verify the calibration with additional weights.
