What is the difference between an electric lift column and a hydraulic lift column?

Lifting column is also called lifting ground column, lifting road pile, anti-collision road pile, hydraulic lifting column, isolation pile, etc. English name Bollard. The word Bollard was originally used to describe short, vertical columns, which were often used when large ships were moored in ports. The term has now been extended to describe facilities that manage pedestrian traffic, protect critical infrastructure, set boundaries and distinguish roads.

Legend has it that street guardrails, shaped like upside-down cannons, began in the 17th century and were used as border Settings and city signs. Since then, they appear more and more in our daily life, and can be seen everywhere, such as supermarkets, restaurants, hotels, shops and sports stadiums. We can often see bollards in various forms, either to indicate the direction of travel, or to protect us from injury, or to tell us whether to stop here. These beautifully shaped bollards beautify the environment, distinguish the sidewalk from the roadway, and sometimes even serve as chairs for us to sit down and enjoy our lunch.

Fixed metal bollards are the most common. They are generally about 36 high painted steel columns, filled with cement and mounted on the ground. Some bollards are rectangular, but most are cylindrical, with angled or flat brims. The bollards come in a wide variety of sizes, colors, textures, shapes and functions. They can be fixed, removable, retractable or used as an ornament to complement the original steel bollards.

Many bollards have aesthetic features, particularly metal bollards, which are used to prevent vehicle damage to pedestrians and buildings, as a simple way to control access, or as guardrails to delineate specific areas. They can be anchored to the ground individually or arranged in a line to keep the road safe from traffic. Metal barriers fixed to the ground act as permanent fences, while retractable and movable barriers allow the entry of certified crowd vehicles.

There are three main applications of bollards - architecture (decoration), security (impact resistance) and landscaping (perimeter projection). All bollards can be architecturally and landscapingly common, differing only in style, shape and material. When it comes to security applications, different bollards are used to block different objects. For example, bollards used to stop traffic are different from bollards used to deal with protection (impact) issues. When it comes to safety applications, the size of the vehicle and the speed of the vehicle at the time of impact should be considered first.
