Working smarter and more efficient with machine control technology

Authors: Per Norell

In 1989, Tommy Berntsson founded Lerbergs Entreprenad AB, and he has used machine control since 2000. Today, Lerbergs Entreprenad uses most of Leica Geosystems’ technologies and services.

“When we make investments, we always choose what we consider to be the best solution. I have been a Leica Geosystems customer for over 20 years, and I feel confident about the technical solutions and support”,explains Berntsson, the company’s vice president.

Lerbergs Entreprenad位于瑞典的Kungsbacka，提供所有类型的建筑和重型建筑工作。在许多项目中，Lerbergs Entreprenad是Skanska，NCC，Peab，Implenia，Serneke和Veidekke等大型公司的分包商。机器舰队由25个挖掘机，车轮装载机和卡车组成。绝大多数机器由挖掘机组成。

汤米·伯恩森（Tommy Berntsson）在机器控制方面有很多经验。“We started using machine control 20 years ago. I realised at an early stage that we could work smarter and more efficiently even when the technology was not as developed as it is today. At that time, we worked with rotating lasers and later on with one and two slope laser control without GPS. A lot has happened the past 20 years, and it feels gratifying to have been part of this development”,says Berntsson.

探索PowerSNAP技术

丹尼尔·劳里森（Daniel Laurison）是一位挖掘机操作员，并在Varberg隧道项目中担任公司的分包商Inplandia。他驾驶了沃尔沃250E挖掘机的追踪，并使用了Leica GeosystemsMCP80panel and theMC1 softwaresince 2019.

Laurison finds the MCP80 panel very practical, especially the PowerSnap feature, allowing simple and fast exchange of the panel between different machines.

“The MC1 machine control solution has a larger display than the old panel, and it is very robust which is an advantage when working in harsh environments. The main advantage for me is the docking station, so that I can quickly take the panel with me. I always remove the panel from the machine, when the day is over and lock it up for safety reasons”, explains Laurison.

The interchangeable Leica MCP80 panel together with the versatile Leica MC1 3D machine control software is developed to use on all heavy machines, including:

• 挖掘机和装载机
• 推土机s and graders
• Pavers, cold planers and rollers
• Drillers and pilers
• Snowgroomers.

While working on the Varberg tunnel project, Laurison benefitted from the cable-free panel with multi-touch screen and hard buttons. Thanks to the easy-to-use interface, compatibility with various heavy equipment and design, he could mount the panel quickly on every different types of machines.“The advantage of MC1 is the easy-to-use interface and the logical order of the project files. The panel gives a good overview of the different categories without going into several submenus to find the right model to work with”, says Laurison.

Better overview of the jobsite with machine control

Lerbergs Entreprenad has been a Leica Geosystems customer for over 20 years.

Daniel Laurison’s colleague, Jim Götthesson, worked on a completely other type of project, an archaeological excavation. Jim drives a Volvo 235E tracked excavator and has not gained a lot of experience with the new machine control solution from Leica Geosystems yet.

“On this particular project, I haven’t used machine control that much, compared to when I work on trenches, foundations or slopes. My first hand impression of the MC1 is that it is a very agile software, where you can move around in the model and see the entire jobsite on the display. I get a better overview and it feels more like a real drawing”，哥特森解释说。

哥特森还解释说，他喜欢学习新技术，尤其是在MC1的情况下，它很容易导航，并且该软件足够直观，可以缩短学习曲线。

“我已经使用了旧技术已经很长时间了，我非常了解，但是学习新事物是开发的一部分。当您获得新软件时，总会有很多东西可以学习”，said Götthesson.

Proximity to a base station is not necessary anymore with satellite positioning

In combination with Leica Geosystems iCON portfolio of machine control solutions, HxGN SmartNet, Hexagon’s GNSS correction service, guides and control earthmoving equipment for precise digging, grading and paving. With more than 4,500 reference stations worldwide, HxGN SmartNet provides the most coverage with 24/7 service.

Lerbergs Entreprenad subscribed some of their machines to SmartNet, receiving GNSS corrections to improve single receiver position accuracy up to centimetre accuracy.

“订阅SmartNet的优势在于，您的束缚不如您对抗基站的束缚。借助SmartNet，我们始终建立联系，即使我们没有可用的项目模型，我们也可以使用高度。”explains Berntsson.

受益于远程support service

When Lerbergs Entreprenad decided to invest in digitalising their fleet, customer care service and support from experts was an important factor choosing Leica Geosystems.

Lerbergs Entreprenad subscribes to Leica Geosystems’ Customer Care Package (CCP), letting them benefit from field support and remote support via internet, software updates, yearly service checks and extended warranty.

“We use all the services in the CCP. The service technicians calibrate the machines and they upgrade the software for us on site”,says Berntsson.

The operators have direct contact with the support department at Leica Geosystems, in case of any problems they can ask for help and benefit from the remote support through the software.

“We are 30 employees, and I haven’t driven excavators for some years now,”says Berntsson.“我不再拥有有关最新技术的详细信息。机器操作员可以直接致电支持而不是通过我来是一个优势。”

Jim Göthesson uses Leica Geosystems’ technical support and has the direct contact to one of Leica Geosystems product expert.“我叫,我当我需要他们的支持,得到帮助p quickly. If the support technician that I normally use can’t solve a problem, he will get help from another technician.”

Why excellent support service is important?

Meet Tommy Berntsson, the founder of Lerbergs Entreprenad.

Most of Lerbergs Entreprenad’s contracts are based on hourly payment and their contractors hire several of their machines and operators. It is important that nothing goes wrong.

“在施工网站上的放行不再非常普遍，因为大部分是在计算机上完成的。如果机器控制解决方案不起作用，则一切都静止不动。因此，对于支持和快速反馈，例如远程支持，这一点很重要。我们等不及几个小时，因为生产静止不动”。explains Berntsson.

Keep up with the technological advancements and become a leader in the market is a key for Lerbergs Entreprenad, but not only for the business but for their employees.

“I want us to be at the forefront of technology in the business,"says Berntsson. “The same counts for the machine fleet, I want new machines with the latest equipment. This is also important for the operators. With good machines and modern technology, the work is more fun and supports their everyday workflows. When we invest, we buy exclusive products.”

Berntsson has been a Leica Geosystems customer for 20 years, among many reasons he highlighted why he feels comfortable working with us:“the technology is leading and the relationship with Leica Geosystems’ experts is uncomplicated. I feel comfortable and safe with them.”
