2). Features:
1, the drill selects the motor through the high-performance reducer as the reverse power; Use cylinders for propulsion. The hydraulic system is eliminated, so the mechanical efficiency is high, the cost is low, and the performance is stable.2, with anti-card maintenance, when the drill is stuck, the motor is not easy to burn, the reducer is not easy to damage.
3, simple and easy to move, the weight of the drill machine is less than 500Kg, and can be broken down into three pieces, easy to move and put on the shelf.
4, the selection of rolling drag plate, the track is not easy to wear.
5, the drilling machine uses semi-automatic cloud dynamic disassembling drill pipe, high efficiency.

  • 1.The selection of the pump is too large, and the flow and head are larger than the actual condition due to improper selection of the coefficient. This situation makes the pump in the operation process, cavitation phenomenon, resulting in premature damage of the pump flow parts under the combined action of cavitation and abrasion, in the case of serious cavitation, the pump will produce vibration and noise, and even lead to a sharp decline in the flow, head and efficiency of the pump can not run; In addition, the pump in the operation of large flow, will also cause motor overload, heat, serious will burn the motor.

  • Architectural bollards can also play a role in promoting sustainability. Eco-friendly materials, such as recycled plastics or sustainably sourced wood, can be utilized in their construction. Furthermore, some designs allow for the incorporation of greenery or planters, contributing to urban biodiversity while softening the often stark urban landscape.


  • A waste dust bin, often referred to as a litter bin or refuse bin, is a receptacle designed for the disposal of waste materials. Unlike conventional bins that might lack segregation options, modern waste dust bins are designed to promote proper waste disposal. They often come with compartments for recyclable materials, organic waste, and general garbage, making it easier for individuals to dispose of their waste responsibly.

  • Nonetheless, the implementation of pedestrian bollards is not without challenges. City planners must carefully consider factors such as placement, spacing, and height to ensure effectiveness without creating barriers that disrupt accessibility for those with disabilities or mobility issues. Engaging the community in the design and placement process can also lead to more successful outcomes, as local residents often have valuable insights about their neighborhoods.


  • - Material Selection Depending on the environment in which they will be used, the choice of material can affect longevity and maintenance. For instance, coastal areas may require materials resistant to corrosion due to salty air.

  • One of the primary roles of bollards with reflectors is to enhance safety for both pedestrians and drivers. Reflective bollards are designed to be easily visible at night and in low-light conditions. This visibility is crucial, particularly in areas where there may be pedestrian traffic close to vehicles, such as parking lots, sidewalks, and street corners. The reflective surfaces help to delineate boundaries, guiding pedestrians away from potential hazards and ensuring that vehicles are aware of restricted zones. This is especially important in busy urban areas where the risk of accidents can be higher.
