To increase the operational efficiency of a mini excavator, it can be optimised and improved in a number of ways. Here are some specific methods and strategies:
Optimise the construction organisation design
Planning the travelling route: the travelling route of the dump truck should be drawn up in advance before construction, and unnecessary uphill roads should be removed. This will ensure that the dump trucks enter and exit smoothly and avoid interfering with each other, thus improving the overall operational efficiency.
Reasonable allocation of vehicles: the number and carrying capacity of dump trucks with excavators should meet the requirements of excavator production capacity. Try to use the double release loading method, so that the excavator is loaded with one, followed by the next one, thus greatly improving the loading efficiency.
Improve the driver’s operating skills
Compound operation: the driver should have skilled operating techniques, and try to use compound operation to shorten the excavator operating cycle time. For example, they can steer left and right while lifting the big arm in order to reach the soil extraction point quickly.
Virtual training: Familiarise yourself with various operation scenarios and operation techniques through operation training in the virtual environment. This training not only improves the operator’s skill level, but also reduces errors and accidents in actual operations.
Maintaining the technical condition of the excavator
Regular maintenance: the technical condition of the excavator has a large impact on its productivity. In particular, the power of the engine and the reliability of the hydraulic system require regular overhaul and maintenance to ensure that the equipment is in top condition.
Replacement of worn parts: Bucket cutting resistance will increase by 60%-90% when the bucket teeth are worn, so worn-out bucket teeth should be replaced. This can effectively reduce mechanical wear and improve operational efficiency.
Adjustment of working parameters
Reasonable adjustment of speed: According to the specific project requirements and soil conditions, reasonably adjust the travelling speed and bucket speed of the excavator. This can ensure that the best operating results can be achieved under different working conditions.
Optimise digging depth: according to the project requirements and construction progress, reasonably adjust the working depth and unloading height of the excavator. This can better adapt to different working environments and improve working efficiency.
Scientific management of the operation process
Establishment of management system: establish a perfect operation management system, and clarify the operation objectives and requirements. Strengthen the supervision and management of the operation process to ensure that the work is carried out in an orderly manner.
Arrange maintenance: Reasonably arrange the maintenance and repair time of the excavator. Ensure the normal operation of the equipment and avoid the interruption of operation caused by mechanical failure.
Applying advanced technology
Artificial intelligence technology: through the application of artificial intelligence algorithms, the automation and intelligence of the operation process can be realised. For example, through the analysis and learning of excavator operation data, an operation model can be established to achieve automatic planning and optimisation of the operation process.
Virtual reality technology: training and training using virtual reality technology. Operators can simulate various operating scenarios in the virtual environment to improve their operating skills and ability to cope with complex situations.
To sum up, improving the operational efficiency of small excavators needs to start from many aspects, including optimising the construction organisation design, improving the operator’s operational skills, maintaining the technical condition of the excavator, adjusting the working parameters, scientifically managing the operational process and applying advanced technologies. The comprehensive application of these measures will help to comprehensively improve the operational efficiency of small excavators, bringing greater convenience and benefits to engineering construction and production activities.
