在道路施工的舞台上，冷再生机堪称 “地面舞者”，通过对旧路面的破碎、拌和与再生，让道路重获新生。然而，这台 “舞者” 能否在复杂多变的施工场地中自如穿梭，离地间隙与通过性起着关键作用。对于租赁冷再生机的施工团队来说，深入了解这些性能要素，才能让设备在施工中发挥最大效能。

　　On the stage of road construction, the cold recycling machine can be called a "ground dancer", which breaks, mixes, and regenerates the old road surface to give it a new life. However, whether this "dancer" can freely shuttle in the complex and ever-changing construction site, the ground clearance and passability play a key role. For construction teams leasing cold recycling machines, a deep understanding of these performance elements is necessary to enable the equipment to achieve maximum efficiency during construction.

　　冷再生机的离地间隙，就像是它的 “安全底线”，直接决定了其在不同地形上行驶的安全性。这个参数指的是设备底部最突出部位到地面的垂直距离。在实际施工中，道路施工现场的地形千差万别，有的路面坑洼不平，布满大大小小的凹陷；有的地方堆积着施工废料或散落的石块；还有的施工现场会有临时搭建的低矮障碍物。如果冷再生机的离地间隙过小，在行驶过程中，设备底部的部件，如传动装置、拌和装置等，就很容易与地面凸起物发生碰撞，不仅可能损坏设备部件，影响施工进度，还可能引发安全事故。例如，在一些老旧城区的道路改造工程中，地下管线施工留下的沟槽、凸起的井盖等，都对冷再生机的离地间隙提出了挑战。一般来说，具备较高离地间隙的冷再生机，能够更轻松地跨越这些障碍，在复杂地形上保持稳定行驶，减少设备受损风险。

　　The ground clearance of the cold recycling machine is like its "safety bottom line", directly determining its safety when driving on different terrains. This parameter refers to the vertical distance from the most prominent part of the bottom of the device to the ground. In actual construction, the terrain of road construction sites varies greatly, with some roads having potholes and uneven surfaces covered in large and small depressions; Some places are piled up with construction waste or scattered stones; Some construction sites may have temporarily erected low obstacles. If the ground clearance of the cold recycling machine is too small, during the driving process, the components at the bottom of the equipment, such as the transmission device, mixing device, etc., are easily collided with the ground protrusions, which may not only damage the equipment components, affect the construction progress, but also cause safety accidents. For example, in some old urban road renovation projects, the grooves and protruding manhole covers left by underground pipeline construction pose challenges to the ground clearance of the cold recycling machine. Generally speaking, cold recycling machines with higher ground clearance can more easily overcome these obstacles, maintain stable driving on complex terrains, and reduce the risk of equipment damage.

　　通过性则是衡量冷再生机能否顺利通过各种施工环境的综合指标，它与离地间隙紧密相关，但又不仅仅取决于此。冷再生机的整机尺寸，包括长度、宽度和高度，对通过性影响显著。狭窄的施工路段，如城市里的小巷、乡村小道，宽度有限，如果冷再生机机身过宽，可能根本无法驶入；而一些桥梁、涵洞等特殊路段，对设备的高度有严格限制，过高的冷再生机将被拒之门外。此外，设备的轴距、轮距以及轮胎的规格和性能，也会影响其通过性。较短的轴距使冷再生机转弯半径更小，在狭窄空间内转弯、掉头更加灵活；合适的轮距有助于设备在松软或不平的地面上保持平衡；具备良好抓地力和胎纹设计的轮胎，能增强设备在泥泞、湿滑路面上的通过能力。比如在山区道路施工时，泥泞的山路和陡峭的坡道，就需要冷再生机拥有出色的轮胎性能和合理的轴距设计，才能安全、高效地完成施工任务。

　　The passability is a comprehensive indicator that measures whether the cold recycling machine can smoothly pass through various construction environments. It is closely related to the ground clearance, but not only depends on it. The overall dimensions of the cold recycling machine, including length, width, and height, have a significant impact on its passability. Narrow construction sections, such as small alleys and country roads in cities, have limited width. If the cold recycling machine body is too wide, it may not be possible to enter at all; However, some special road sections such as bridges and culverts have strict height restrictions on equipment, and excessively high cold and fresh air will be rejected. In addition, the wheelbase, wheelbase, and tire specifications and performance of the equipment can also affect its passability. The shorter wheelbase makes the turning radius of the cold recycling machine smaller, making it more flexible to turn and make U-turns in narrow spaces; Appropriate wheelbase helps equipment maintain balance on soft or uneven ground; Tires with good grip and tread design can enhance the equipment's ability to pass through muddy and slippery roads. For example, during road construction in mountainous areas, muddy mountain roads and steep slopes require cold recycling machines to have excellent tire performance and reasonable wheelbase design in order to safely and efficiently complete construction tasks.

　　在租赁冷再生机时，施工团队必须根据具体的施工项目需求，仔细考量设备的离地间隙与通过性。在施工前，对施工现场进行详细勘察，了解地形地貌、道路状况、障碍物分布等信息，据此选择适配的冷再生机。如果施工场地地形复杂，障碍物多，就应优先选择离地间隙大、整机尺寸紧凑、通过性强的设备；若施工区域相对平坦开阔，则可在满足基本施工要求的前提下，综合考虑其他性能参数。同时，租赁后也要对设备进行必要的检查和调试，确保轮胎气压正常、部件连接稳固，以保障冷再生机在施工过程中始终保持良好的通过性能，让这台 “地面舞者” 在道路施工的舞台上尽情施展技艺，高效完成施工任务。

　　When leasing a cold recycling machine, the construction team must carefully consider the ground clearance and passability of the equipment based on specific construction project requirements. Before construction, conduct a detailed survey of the construction site to understand the terrain, road conditions, obstacle distribution, and other information, and based on this, select the appropriate cold recycling machine. If the terrain of the construction site is complex and there are many obstacles, priority should be given to selecting equipment with large ground clearance, compact overall size, and strong passability; If the construction area is relatively flat and open, other performance parameters can be comprehensively considered while meeting the basic construction requirements. At the same time, necessary inspections and debugging of the equipment should be carried out after leasing to ensure normal tire pressure and stable component connections, in order to ensure that the cold recycling machine maintains good passing performance during the construction process, allowing this "ground dancer" to fully display their skills on the stage of road construction and efficiently complete construction tasks.
