Essential Tips | Field Operation Techniques and Standards for Crane Maintenance

As an indispensable piece of critical equipment in the industrial sector, the stable operation of cranes

directly impacts the smooth progress of construction sites and production processes. However, during actual

operation, cranes inevitably encounter various malfunctions and issues, making timely maintenance and

servicing particularly crucial.

HG Crane has been deeply rooted in the industry for 18 years, specializing in crane repair and

maintenance services. We have accumulated extensive experience and secured multiple proprietary

patents. Within the crane repair field, HG Crane has amassed substantial expertise, particularly in bridge crane

maintenance.

HG Crane's proprietary digital display instrument overcomes the limitations of traditional maintenance

approaches, which rely excessively on experience-based judgment, struggle to achieve precise adjustments,

and often resort solely to component replacement to resolve issues. This results in significant waste of time,

funds, and manpower. By utilizing its independently patented digital display instrument, HG Crane has

successfully achieved accurate digital display of measurement errors. This innovative technology effectively

addresses the challenging issues encountered in bridge cranes during prolonged high-intensity operation, such

as rail gnawing, abnormal wheel noise, and unstable operation caused by factors including load stress,

foundation settlement, and equipment aging.

To further enhance the efficiency and quality of crane maintenance work, the HG Crane maintenance team

has compiled and summarized a series of practical on-site operational techniques and standards for crane

maintenance. These are now shared for reference and discussion.

                                                                  Operating Techniques

1. Pre-Maintenance Preparations Before commencing crane maintenance work, maintenance personnel must

conduct a comprehensive survey of the maintenance site. It is essential to gather foundational information

such as the crane model, specifications, parameters, and the specific nature of the malfunction, as this data is

critical for subsequent repair efforts. Additionally, all necessary tools and materials required for the repair

must be prepared in advance to ensure the maintenance process proceeds smoothly without delays caused by

shortages of tools or materials.

2. Safety First During Crane Maintenance Safety remains the paramount concern throughout crane

maintenance operations. Maintenance personnel must maintain a high level of safety awareness at all times.

First, safety signage must be prominently displayed at the maintenance site, with appropriate caution tape

erected to clearly demarcate the safety zone and ensure a secure working environment.

Second, maintenance personnel must wear standard-compliant personal protective equipment (PPE),

including hard hats, professional workwear, and protective gloves, to ensure comprehensive personal safety.

Finally, when operating cranes, strictly adhere to every step outlined in the operating manual to guarantee

stable and safe crane operation, eliminating any potential safety hazards. HG Crane Maintenance

consistently prioritizes safety as its foremost principle, having meticulously developed a rigorous

standardized operating manual to institutionally safeguard the maintenance site.

3. Practical Maintenance Techniques

3.1 Troubleshooting and Fault Localization

At the maintenance site, technicians must swiftly pinpoint crane malfunctions using their expertise.

Conduct thorough investigations based on observed symptoms and equipment-generated fault codes.

Common crane failures primarily involve mechanical and electrical issues. Facing different fault types,

technicians must make rapid, accurate judgments and implement targeted repair measures to resolve

problems efficiently.

3.2  Key Points for Component Replacement

During maintenance, any damaged or failed components must be replaced promptly. Maintenance personnel

should select the correct replacement parts based on the crane's specific specifications and model.

The replacement process must strictly follow standard procedures to ensure seamless integration of

new components, enabling normal operation and safeguarding the crane's overall performance.

3.3 Failure Prevention Measures

To effectively reduce the probability of crane failures and minimize equipment damage,

maintenance personnel must conduct comprehensive maintenance work on a regular basis.

This includes lubricating critical components, cleaning and dusting the body and all parts,

and tightening loose components to ensure every part of the crane remains in optimal operating condition.

Additionally, detailed records of maintenance activities must be kept during crane servicing.

These records serve as vital references for subsequent repairs, facilitate fault analysis,

and continuously enhance the quality and efficiency of maintenance work.

3. Workflow

(1) Assess the situation: Gather basic information such as the crane's model, specifications,

and fault condition.

(2) Set up safety signage: Place safety signs at the repair site and establish a safety perimeter

to ensure the work area is secure.

(3) Prepare tools and materials: Gather all necessary tools and materials for the repair task.

(4) Troubleshoot: Diagnose the crane's malfunction based on fault symptoms and error codes.

(5) Replace Components: Select and install correct replacement parts according to the crane's specifications

and model.

(6) Maintenance: Perform regular lubrication, cleaning, and tightening to minimize crane failures.

(7) Documentation and Summary: Record repair details for future reference and fault analysis.

5. Safety Regulations

Safety at crane maintenance sites is paramount. Personnel must adhere to the following safety regulations:

(1) Safety Equipment: Wear standard-compliant personal protective equipment, such as hard hats,

work uniforms, gloves, etc.

(2) Operating Procedures: Strictly follow the requirements of the operating manual to ensure stable and

safe crane operation.

(3) Accident Prevention: Maintain constant vigilance over safety at the maintenance site,

establish safety signage and warning lines to prevent accidents.

6. Maintenance Quality

Maintenance quality is the cornerstone of crane maintenance work. Personnel must adhere to the

following standards to ensure maintenance quality:

(1) Component Selection: Select the correct replacement components based on the crane's specifications

and model.

(2) Operational Standards: Strictly follow operational procedures to ensure replaced components

function properly.

(3) Maintenance and Inspection: Perform regular lubrication, cleaning, and tightening to minimize the

likelihood of malfunctions.

In summary, employing proper operating techniques and standardized maintenance procedures

can enhance the efficiency and quality of crane maintenance work. In practical operations,

personnel must strictly adhere to the operating manual and regulatory requirements,

maintain constant vigilance for safety, and perform tasks such as troubleshooting, component replacement,

and routine maintenance to ensure the crane's normal operation. Only through such measures

can the smooth progress of crane operations during construction and production be guaranteed.
