1. Work requirements: First, consider the specific work requirements and application scenarios. Different job tasks and material types may require different types and sizes of breakers. For example, for crushing tasks of large rocks or concrete, a larger size and high energy breaker needs to be selected.
2. Adapting equipment: The breaker needs to be matched with excavators, loaders or other construction machinery and equipment. Make sure that the breaker attachment, size and weight are appropriate for the equipment being used to ensure compatibility of installation and operation.
3. Construction environment: Consider the characteristics and constraints of the construction environment. For example, some engineering projects may have noise, vibration or space constraints that require the selection of a low-noise, low-vibration or compact breaker.

4. Durability and quality: Choose a breaker with good durability and high quality to ensure long-term reliable operation and less maintenance costs. Pay attention to factors such as brand reputation, product quality certification, and after-sales service provided by the manufacturer.
5. Performance and efficiency: Consider the performance indicators of the breaker, such as striking energy, striking frequency, crushing speed, etc. High-efficiency and high-performance breakers can improve work efficiency and production capacity.
6. Safety performance: Breaking hammers need to have certain safety performance protection measures, such as protective covers, protective devices, protective valves, etc., to reduce the risk of accidents and personal injury.
7. Maintenance and repair: Understand the maintenance requirements of the breaker and the replacement cycle of wearing parts, as well as the after-sales maintenance and support services provided by the manufacturer. Choosing a breaker that is easy to maintain and service can reduce downtime and repair costs.
Taking the above factors into consideration, you can choose a breaker that suits your work needs and budget, and consult a professional breaker supplier or manufacturer for more technical support and advice.
