利勃海尔R926 Compact紧凑型无尾挖机模型 合集

R926 Compact是德国LIEBHERR利勃海尔的紧凑型挖机，在国内又被称为无尾挖机。
PREMACON从利勃海尔获得了正式的授权来生产该型号的模型机。
据PREMACON透露，R926将遵照原型机来设计，从外形到功能，以及到液压快接系统，都和原型机近似。
而这台R926模型的重量只有14kg！

首先让我们来看一组R926挖机模型在室外的场景照片：















以下是较早前在室内拍摄的样机的照片：

利勃海尔R926模型挖机自动换铲功能演示

可能你已经注意到了，视频中这台R926 Compact挖机模型采用了利勃海尔的LIKUFIX油路自动快接系统，提供了一个液压锁止机构和两个液压回路。
除此之外，你还能看到两个扩展的电路系统，它将由Servonaut MFX控制器控制，从而为其他有趣的附件提供更丰富的功能。这个设计是R926独有的，我们称之为：Scale in a new dimension！

除了标准铲之外，PREMACON目前以为926推出了两款扩展工具。
此外，已知的情况是：为926设计的铲和工具，与其他机型是不兼容的，只能用于926.

以下两条视频，让我们看看利勃海尔260真挖机的作业现场和外观展示：

The Original performance

The R 926 Compact combines the power and versatility of a standard device with a smaller footprint of a short tail excavator and is therefore an ideal solution for inner-city construction sites.  With a wide range of work equipment and options, this machine can be used for earthmoving, canal construction or can be configured for any type of demolition work.

Reliability

With over 50 years of experience in the development of crawler excavators Liebherr offers its customers machines from highest reliability. The high quality of the product is guaranteed at all stages from design to final assembly. The working conditions for the operator are made safer and safer. This recognised reliability can also be found in the many services we offer Liebherr, which were specially developed to support and satisfy our customers.

Comfort

The cab of the R 926 Compact is not only extremely comfortable and spacious, it also offers an excellent view of the working environment and is equipped with
The excavator is equipped with the latest technology, allowing the operator to exploit the full performance potential of this excavator in a very pleasant working environment.

Economy

The new maintenance concept of the R 926 Compact helps to reduce downtimes and thus increases productivity.
In addition, the extremely intelligent energy management and automatic tool change reduce operating costs.

hydraulic system

The model hydraulics were taken over from the large models R946/R956.

We use a large-volume pump and our large valves.

These offer excellent fine controllability and longevity.

The scale appearance of the hydraulic cylinders and the piping once again sets the standard.

- PREMACON/Kampshoff SILENT PUMPE DRIVE (whisper quiet pump with excellent controllability at lowest speeds)

- Optimise line cross-sections for optimum use of hydraulic power

- Hydraulic valves made of industrial steel from the company Jung Fluidtechnik

- hard piped cylinder lines

- Hydraulic cylinder with screwed heads completely dismountable; industrial seals with wiper;

  hard chrome plated piston rods; cast cylinder eyes (low internal friction thus more pressure is converted into working power)

- Large-volume tank with special internal geometry to ensure oil production even at extreme inclined positions; no foaming; no temperature problems

- Hydraulic filter integrated in the tank

- Working pressure approx. 22 bar

Optional: dozer blade and support blade with hydraulic rotary union and shut-off valve



Electronics

- Controller parameters specially designed for the pump motor

- Servonaut MFX controller for chain drive and swivel drive

- Industrial rotary union for endless turning of the upper carriage

- Special POWER LED's as headlights

- 7.5 A Power BEC

- HiTec brand servos for hydraulic valve control

- Operating voltage: 12 V Nimh or 3S Lipo cells



Special equipment or accessories not included in the basic kit

- Hydraulic set, drive set, electronics set, auxiliary hydraulics, painting and assembly

- Stone chip protection for cabin complete (roof and front sash)

- Individual stone chip protection either roof or front sash

- Quickcoupler mechanical

- Hydraulic quick coupler

- additional headlights on the boom and under the cabin

- Support and levelling blade

- Chain guide drive Heavy Duty

- Likufix system with one hydraulic circuit and 2 electric control circuits (MFX controller)
