1、 工程机械之装载机的英语翻译Unit 8 Loaders装载机8.1 Overview概述8.1.1 Basic Concept 基本概念A loader is a type of construction equipment (engineering vehicle) machinery that is primarily used to load material into another type of machinery (dump truck, conveyor belt, rail-car, etc.).Loaders are used mainly for uploading m

2、aterials into trucks, laying pipe, clearing rubble, and digging. A loader is not the most efficient machine for digging as it cannot dig very deep below the level of its wheels, like a backhoe can. Their deep bucket can usually store about 3-6 cubic meters of earth. The front loaders bucket capacity

3、 is much bigger than a bucket capacity of a backhoe loader. Loaders are not classified as earthmoving machinery, as their primary purpose is other than earthmoving.装载机是一种主要用于向另一种机械（自卸车、输送皮带、铁路运输车辆等）“装载”物料的建设机械（工程车辆）设备。装载机主要用于向卡车装载物料，以与铺设管道、清理碎石和挖土等工作。作为挖土作业装载机不是最有效的机械，与挖掘机不同，装载机不适用于轮胎支承面以下较深处的挖掘作业。装

4、载机的深底铲斗一般可装载36立方米的土壤。铲斗前置装载机的斗容量远大于挖掘装载机的斗容量。装载机不属于铲土运输机械，因其主要用途并非土方运输。Unlike most bulldozers, most loaders are wheeled and not tracked, although track loaders are common. They are successful where sharp edged materials in construction debris would damage rubber wheels, or where the ground is soft a

5、nd muddy. Wheels provide better mobility and speed and do not damage paved roads as much as tracks, but provide less traction.尽管履带式装载机是普遍的，但与大多数推土机不同，大多数装载机是轮式的而并非履带式。履带式装载机适用于棱角锐利的建筑材料会破坏橡胶轮胎的场合，或者在松软泥泞道路上的作业。轮式装载机具有良好的机动性和较高的工作速度，并且不像履带那样破坏铺装路面，但其所能提供的牵引力较小。Unlike standard tractors fitted with a f

6、ront bucket, many large loaders do not use automotive steering mechanisms. Instead, they steer by a hydraulically actuated pivot point set exactly between the front and rear axles. This is referred to as articulated steering and allows the front axle to be solid, allowing it to carry greater weight.

7、 Articulated steering provides better maneuverability for a given wheelbase. Since the front wheels and attachment rotate on the same axis, the operator is able to steer his load in an arc after positioning the machine, which can be useful. 与安装前置铲斗的标准拖拉机不同，许多大型装载机不使用汽车转向机构。取而代之，它们通过液压驱动的安装于前、后桥之间的转向

8、铰接装置转向。这种转向称为“铰接转向”，它可使前桥固定，并使其承受更大的重量。对于一定的轴距铰接转向提供了较好的机动性。由于前轮与工作装置绕同一车轴旋转，驾驶员在使机械定位后可使铲斗沿弧线“转向”，这一点是实用的。The loader assembly may be a removable attachment or permanently mounted. Often the bucket can be replaced with other devices or tools-for example, many can mount forks to lift heavy pallets or

9、 shipping containers, and a hydraulically-opening clamshell bucket allows a loader to act as a light dozer or scraper.装载机的工作装置可以是更换式的或者是固定安装。铲斗常常可用其它装置或工具更换，例如，许多装载机可以安装叉车工装提升重型货物或者装运集装箱，装备液压开启式“蛤壳”型铲斗可以使装载机像推土机或铲运机一样作业。In construction areas loaders are also used to transport building materials - su

10、ch as bricks, pipe, metal bars, and digging tools - over short distances.Loaders are also used for snow removal, using their bucket or a snowbasket, but usually using a snowplow attachment. They clear snow from streets, highways and parking lots. They sometimes load snow into dump trucks for transpo

11、rt.在各种建筑工地上装载机也经常用来近距离转运建筑材料，例如砖块、管材、钢筋、各种挖掘工具等。借助铲斗或除雪铲，装载机也用于除雪作业，但通常使用除雪装置。它们用来清除街道、公路和停车场上的积雪。有时用装载机将积雪装载到自卸车上进行运输。Front loaders gained popularity during the last two decades, especially in urban engineering projects and small earthmoving works. Many engineering vehicle manufacturers offer a wid

12、e range of loaders, the most notable are those of John Deere, Caterpillar, Case, Volvo, Komatsu and Liebherr.近20年来，特别是在城市建设工程和小型土方运输工程中，装载机获得了普遍的应用。许多工程车辆制造商可生产多种类型的装载机，其中最知名的有约翰迪尔、卡特彼勒、凯斯、沃尔沃、小松和利勃海尔等品牌。8.1.2 Applications应用 1 2 3 4 5 6 7 8 9 10 11 121. loading materials装载材料；2. earthmoving铲土运输；3. fo
