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”,该公司副总裁Berntsson解释说。

Lerbergs Entreprenad is located in Kungsbacka, in Sweden and offers all types of building and heavy construction work. In many of the projects, Lerbergs Entreprenad acts as sub-contractor for larger companies such as Skanska, NCC, Peab, Implenia, Serneke and Veidekke. The machine fleet consists of 25 excavators, wheel loaders and trucks. The vast majority of machines consists of excavators.

汤米·伯恩森（Tommy Berntsson）在机器控制方面有很多经验。“我们20年前开始使用机器控制。我在早期阶段意识到，即使技术不像今天那样发展，我们也可以更聪明，更有效地工作。当时，我们使用旋转激光器，后来在没有GPS的一个和两个斜率激光控制下进行。过去20年发生了很多事情，成为这一发展的一部分感到很高兴。”says Berntsson.

Exploring the PowerSnap technology

Daniel Laurison is an excavator operator and works on the Varberg tunnel project as a sub-contractor for the company Implenia. He drives a tracked Volvo 250E excavator and has used Leica Geosystems’MCP80panel and theMC1软件since 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.

可互换的Leica MCP80面板以及多功能Leica MC1 3D机器控制软件都开发用于所有重型机器，包括：

• 挖掘机和装载机
• 小吃者和分级人士
• Pavers, cold planers and rollers
• Drillers and pilers
• 雪地者。

在进行Varberg隧道项目时，Laurison从无线电面板中受益于带有多点触摸屏和硬按钮。由于易于使用的界面，与各种重型设备和设计的兼容性，他可以在所有不同类型的机器上快速安装面板。“ MC1的优点是易于使用的接口和项目文件的逻辑顺序。该小组对不同类别进行了很好的概述，而无需进入几个子菜单以找到合适的模型与众不同”，劳里森说。

通过机器控制更好地概述工作现场

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。

Götthesson also explained that he enjoys learning new technologies, especially with the MC1, it is easy to navigate and the software is intuitive enough to shorten the learning curve.

"I have used the old technology for a long time, and I know it very well, but it is part of the development to learn new things. When you get a new software, there is always quite a lot to learn",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将其一些机器订阅到SmartNet，并接受GNSS校正，以提高单个接收器位置的精度，直到精度。

“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。”解释说伯恩森。

Benefitting from remote support service

当Lerbergs Entreprenad决定投资数字化车队时，专家的客户服务和支持是选择Leica Geosystems的重要因素。

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.

“我们是30名员工，几年来我还没有驱动挖掘机。”says Berntsson.“I no longer have detailed information about the latest technology. It is an advantage that the machine operators can call support directly instead of going through me.”

Jim Göthesson uses Leica Geosystems’ technical support and has the direct contact to one of Leica Geosystems product expert.“当我需要他们的支持时，我会致电他们，并且很快就会获得帮助。如果我通常使用的支持技术人员无法解决问题，他将从其他技术人员那里得到帮助。”

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.

“Stakeout on the construction site is not very common anymore, because most of it is done on the computer. If the machine control solution is not working, everything stands still. It is therefore important with support and quick feedback, as for example remote support. We can’t wait several hours, because the production is then standing still”,解释说伯恩森。

跟上技术进步和come 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.”
