What Should Be Done If A Marine Crane Breaks Down Suddenly? BOB-LIFT Expert Q&A Offers You Tips

I. Emergency Guide for Common Faults: A Quick Consultation Sheet for the "Doctor" of Ship Cranes

Q1: What could be the reasons for the slow and weak movement of the ship crane?

Possible causes:

Hydraulic system issues: insufficient or contaminated hydraulic oil, internal leakage in the hydraulic pump, and jamming of the control valve core.

Power source issue: The engine or motor speed has not reached the rated value, resulting in insufficient power output.

Emergency self-inspection

First, check the oil level: Inspect whether the oil level in the hydraulic oil tank is within the standard range.

Listen to the sound: Listen for any abnormal suction sounds or sharp noises from the hydraulic pump.

Check the pressure: Observe whether the pressure gauge of the system is normal.

BOB-LIFT Solution Outlook: Our equipment is equipped with a hydraulic oil cleanliness alarm device and a large-capacity high-efficiency filter, which can effectively prevent system failures caused by oil contamination and extend the service life of hydraulic components.

Q2: If the ship crane makes abnormal noises during operation (such as metal friction or impact sounds), should it be taken seriously?

Possible causes:

Loose structural connection parts: such as loose bolts and pins, causing abnormal friction between components.

Problems with steel wire ropes or pulleys: Steel wire ropes jump out of place, broken wires, or damaged pulley bearings.

Mechanical component wear: Lack of lubrication or excessive wear of key moving parts such as slewing bearings and drums.

Emergency self-inspection

Stop the machine immediately: Abnormal noises are an alarm of major safety hazards and operations must be halted immediately.

Visual inspection: Focus on inspecting the steel wire rope, pulley block and visible connection parts.

BOB-LIFT Solution Outlook: BOB-LIFT ship cranes are made of high-strength alloy steel and feature precise manufacturing processes. Key connection points are designed with anti-loosening features. It also provides a centralized lubrication system (optional) to ensure that key components are properly lubricated, reducing wear and abnormal noise from the root.

Q3: Has the lifting capacity declined, or even unable to lift the rated weight?

Possible causes:

Overload protection device malfunction or failure: sensor failure or set value drift.

The set pressure of the safety valve is too low: It needs to be calibrated by professional technicians.

There is severe internal leakage in the structure or hydraulic system.

Emergency self-inspection

Forced lifting is strictly prohibited! This is the most important safety red line.

Check the instrument: See if the overload alarm system gives a prompt.

BOB-LIFT Solution Outlook: BOB-LIFT is equipped with multiple safety protection systems, including high-precision torque limiters (LMI) and overload protection devices, which monitor the load in real time. With high precision and strong reliability, it not only protects the equipment from overloading but also ensures operational safety.

Q4: Operating system failure (such as no response, disordered operation)?

Possible causes:

Electrical system faults: controller freeze, sensor signal interruption, loose or short circuit lines.

The pilot control handle is faulty.

Emergency self-inspection

Try restarting: Turn off the main power supply, wait for one minute and then restart to see if it can reset.

Check the wiring: A rough inspection can reveal whether there is any obvious damage to the wiring or loose plugs.

BOB-LIFT Solution Outlook: Our electronic control system adopts a modular, waterproof and shockproof design with firm interfaces, capable of adapting to harsh Marine environments. The intelligent controller is equipped with a self-diagnostic function, which can quickly locate the fault point and significantly reduce the maintenance time.

Ii. Beyond Fault Response: BOB-LIFT's "Prevention before It Happens" Approach

The above self-inspection methods can help you deal with unexpected situations, but the most efficient way is to avoid malfunctions from occurring. The design philosophy of BOB-LIFT is that "active prevention" is superior to "passive maintenance".

Robust Design: From material selection to structural simulation, we adhere to design standards that exceed industry standards to ensure the inherent sturdiness and durability of the ship crane.

Intelligent Monitoring and Early Warning (Optional) : We offer a remote monitoring system that can transmit real-time equipment operation data (such as working hours, load records, fault codes) to the shore-based management center, enabling predictive maintenance and issuing early warnings before faults occur.

Professional global service network: No matter where your vessel is, BOB-LIFT's global service network can provide timely technical support, original factory spare parts and professional maintenance services, allowing you to have no worries.

Choose BOB-LIFT, choose a reliable one that never stops

The reliability of the ship crane is directly related to your operational profits and safety. Choosing BOB-LIFT is not merely about selecting a high-quality ship crane; it's about choosing a complete solution that encompasses intelligent design, proactive prevention, and global response.
