发动机和液压装置

发动机

强劲、可靠、经济和排放低的六缸涡轮增压发动机使挖掘机运转良好。

Automatic Engine Speed Control

Automatic Engine Control with convenient one-touch command. During no-load or light-load conditions, the Automatic Engine Speed reduces engine speed. This maximizes fuel efficiency and reduces sound levels.

操纵性能

液压系统为 325C 提供精确的控制，减轻驾驶员疲劳，提高驾驶员的效率，最终归结为机器性能的提高。

液压交叉传感系统

随着工作部件速度的加快、以及旋转轴更快和更有力的转动，生产率也得以提高。

Component Layout

The 320D hydraulic system and component locations have been designed to provide a high level of system efficiency. The main pumps, control valves and hydraulic tank are located close together to allow for shorter tubes and lines between components, which reduce friction loss, and pressure drops in the lines. The layout further provides greater operator comfort by placing the radiator on the cab side of the upper structure. This allows incoming air to enter the engine compartment from the operator side and hot air and corresponding engine sound to exit on the opposite side away from the operator. This reduces engine compartment heat and sound being transmitted to the operator.

Pilot System

The pilot pump is independent from the main pumps and controls the front linkage, swing and travel operations.

Hydraulic Cross Sensing System

The hydraulic cross sensing system utilizes each of two hydraulic pumps to 100 percent of engine power, under all operating conditions. This improves productivity with faster implement speeds and quicker, stronger pivot turns.

Auxiliary Hydraulic Valve

The auxiliary valve is standard on the 320D. Control Circuits are available as attachments, allowing for operation of high and medium pressure tools such as shears, grapples, hammers, pulverizers, multi-processors and vibratory plate compactors.

Boom and Stick Regeneration Circuit

Boom and stick regeneration circuit saves energy during boom-down and stick-in operation which increases efficiency, reduces cycle times and pressure loss for higher productivity, lower operating costs and increased fuel efficiency.

Hydraulic Cylinder Snubbers

Snubbers are located at the rod-end of the boom cylinders and both ends of the stick cylinders to cushion shocks while reducing sound levels and extending component life.

驾驶台

325C 驾驶员工作台非常安静，其操纵杆布置符合人机工程学，便于调整；操纵杆和踏板操作起来比较省力；座椅按人机工程学设计；并且具有高效通风的驾驶室。

结构

机器人焊接

卡特彼勒挖掘机上的焊接钢结构有多达95%是由机器人完成的。机器人焊接的焊透力可达人工焊接的3倍。

行走装置

结实的卡特彼勒行走装置吸收了应力并提供极佳的稳定性。

Booms and Sticks

Booms, Sticks and Attachments

Designed for maximum flexibility, productivity and high efficiency on all jobs, the 320D offers a wide range of configurations suitable for a variety of applications.

工装附件

铲斗

卡特彼勒铲斗可减少修理费用增长使用寿命。所有铲斗都用双半径设计以增大与地面的间隙以减小磨损。铰接组件和其它关键地方均采用机器人焊接以增大焊透性并具有更长的使用寿命和更高的强度。

大容量挖掘铲斗（MX）

大容量挖掘铲斗负载因数高，使得生产率较高，设计用于大量运土和装载。大容量型挖掘铲斗外形与挖掘铲斗相同，但尺寸更宽，挖掘容量更大。

挖掘铲斗（X）

挖掘铲斗设计为一般用途挖掘，挖掘范围从摩擦系数低的松软土壤到中等摩擦系数的坚硬土壤。

监控器r

可选用的工装控制系统，最多有5种不同的工装设定可以预编程并通过监控器从电子控制器进行选择。

Cat thumbs multiply the capacities of your excavator. This highly versatile tool works in conjunction with the bucket to transform an excavator into a versatile material-handling machine.

工装控制系统

选用的工装控制系统可控制各种工装，并使用标准的或者附件控制机构充分发挥工装的生产率，同时通过设定液压装置流量、压力和驾驶员控制机构与最多5种预先编程的工装配合。

Multi-processors do the work of many types of demolition tools by use of interchangeable jaw sets. Changing jaws allows a single unit to crush, pulverize and perform a variety of specialized cutting tasks, such as cutting steel rebar and tanks.

Caterpillar Vibratory Plate Compactors provide superior compaction force in a reliable, low-maintenance package. These units produce high-power impulses at a rate of 2,200 impacts per minute. The forces generated by this vibration drive soil particles close together for solid, stable compactions. Whether in a trench or on a slope, driving sheeting or posts, Cat Compactors are the superior choice for any jobsite’s compaction tasks.

Caterpillar Scrap Shears feature 360° rotation and a high force-to-weight ratio. Used for demolishing steel structures, and preparing bulk scrap (such as cars, farm machinery and railroad cars) for further processing.

Pin-Grabber Plus Quick Couplers multiply the versatility and utility of Cat Excavators by allowing them to pick up and use virtually any work tool equipped with standard pins.

Dedicated Quick Coupler

Quick Couplers increase the versatility of Cat excavators; allowing the ease of changing work tools to meet job requirements at hand in a matter of minutes or seconds. Dedicated quick coupler buckets have no loss of tip radius, and develop maximum breakout force.
