Container front crane is a type of crane used to load and unload containers. It is a type of lifting equipment. The maintenance of container front crane boom is an important part of ensuring the safe operation of the equipment and extending its service life.
1. Daily inspection and maintenance/Inspección y mantenimiento diarios
Hydraulic system inspection/Inspección del sistema hidráulico
Oil level and oil quality: Check whether the hydraulic oil level is within the standard range, observe the color and transparency of the oil, if it is turbid or contains impurities, replace it in time.
Leaks and pipelines: Check the hydraulic pipelines and joints for leaks, paying special attention to the sealing of the telescopic cylinder and the luffing cylinder.
Pressure test: Regularly test the steering pressure (17.5±0.5MPa) and accumulator pressure (pre-charge pressure 10±0.5MPa) to ensure compliance with standards.
Lubrication management/Gestión de la lubricación
Lubrication points: Add grease to key parts such as the boom slider, pin shaft, steering knuckle, etc. periodically to prevent sticking or wear due to insufficient lubrication.
Lubrication channel: Check whether the lubrication nozzle is blocked, clean out impurities in the lubrication pipeline, and avoid the pin shaft from being stuck.
Structural parts inspection/Inspección de piezas estructurales
Welds and corrosion: Regularly check whether there are cracks in the boom welds, whether there is corrosion or deformation in the straight web and other parts, and perform non-destructive testing (such as ultrasonic or X-ray testing) when necessary.
Fastening of connecting parts: The fixing seat and pin on the basic arm are the main parts connecting the frame and the sling. The structure and welding of the fixing seat, the stability of the pin, pin hole bearing and fixing bolts need to be checked regularly. Pay special attention to the connection between the main chord and the web.
2. Regular maintenance plan/Plan de mantenimiento regular
Hydraulic system maintenance/Mantenimiento del sistema hidráulico
Replace hydraulic oil and filter element: Replace the hydraulic oil every 500-1000 hours and replace the high-pressure filter element simultaneously to prevent oil contamination from causing valve core sticking.
Cleaning system: If the oil is found to contain impurities, the hydraulic system must be thoroughly cleaned and the filter element replaced.
Key component maintenance/Mantenimiento de componentes clave
Solenoid valve and multi-way valve: Clean or replace any solenoid valve that may be stuck, and check whether the multi-way valve core moves flexibly.
Braking system: Check the wear of the brake disc, adjust the brake spring pressure, and ensure that the parking brake is effectively locked on an 18% slope.
Electrical system inspection/Inspección del sistema eléctrico
Circuits and sensors: Clean electrical components, check whether the solenoid valve circuit contact is good, and test the functions of anti-tilt sensors and twist lock safety interlock devices.
3. Common faults and solutions/Fallos comunes y soluciones
Abnormal extension and retraction of the boom/Extensión y retracción anormales de la pluma
Hydraulic leakage: If the boom cannot be extended or retracted, it may be due to internal leakage in the hydraulic system (such as insufficient pressure in the working pump or failure of the overflow valve). It is necessary to check the sealing of the cylinder and the leakage point of the circuit.
Valve core stuck: If the proportional valve is stuck due to oil contamination or high temperature, the hydraulic oil needs to be replaced and the system cleaned.
Jittery or delayed motion/Movimiento nervioso o retrasado
The connection gap is too large: check the gap between the pin and the fixed seat, and replace the worn thrust bearing or fastening bolts.
Brake system failure: If the arm stops too slowly after rotation, the brake disc needs to be replaced or the spring pressure needs to be adjusted.
4. Safety regulations and precautions/Normas y precauciones de seguridad
Operational safety/Seguridad operacional
Before maintenance, the machine must be shut down and the power must be cut off, warning signs must be hung, and blocks must be set to prevent the equipment from moving.
During emergency descent, the order of “retracting the arm first and then lowering the arm” must be followed to avoid the risk of tipping over.
/
Keep the maintenance site clean and tidy, prevent fire and explosion, and record the details of each maintenance and repair for subsequent analysis.
5. Example of recommended maintenance cycle/Ejemplo de ciclo de mantenimiento recomendado
1) Hydraulic oil replacement: replace the oil and filter element every 500-1000 hours and clean the system.
2) Lubrication of key lubrication points: Lubricate the pins, sliders and other parts every 8 hours/day
3) Nondestructive testing of structural parts: annual testing of welds and corrosion areas
4) Brake system inspection: adjust brake pressure every month and check wear parts
Summarize:
The above measures can effectively prevent boom failure and ensure efficient operation of the equipment. The specific maintenance plan needs to be formulated in combination with the equipment model and manufacturer’s manual, and operators should be trained regularly to improve maintenance standardization.
Mediante las medidas anteriores, se pueden prevenir eficazmente fallas de la pluma y se puede garantizar el funcionamiento eficiente del equipo. Es necesario formular planes de mantenimiento específicos en combinación con el modelo del equipo y el manual del fabricante, y los operadores deben recibir capacitación periódica para mejorar los estándares de mantenimiento.
