The camera is fixed on the tower crane jib, at the end or along the jib, making sure it doesn’t prevent the trolley movements and the trolley doesn’t obstruct the camera lens. The optimal location is dependent on the site configuration. We recommend the camera to be positioned over the center of the building site.
The system is fixed on the crane using a bracket supplied by Pix4D. Depending on the crane model and manufacturer, you may need to modify this bracket. You will be responsible for the mounting, Pix4D is not accredited to conduct operations on the crane and thus will not take any liability for this.
It should point straight down to ensure good 2D mapping results.
Yes, at present the system is designed to have the camera pointing down during data capture. Future developments will allow the solution to be compatible with luffing jibs.
It is powered by the crane power system using a cable, typically from the cabin or from sockets available along the jib. A 2m cable will be attached. The cable is a 3 wire cable (L, N, GND).
Power requirement depends on the input voltage type:
AC input voltage = ~50W max with heater active (case temperature < 5 C), ~15 W max without heater DC input voltage= ~15 W max.
The system can be configured to accept many types of voltage:
100-240 VAC via a supplied adapter inside the camera case. This option includes a case heater (case temperature < 5 C) 8-28 VDC via built-in converter. There is currently no case heater for DC voltages
Images are automatically and wirelessly sent to the Pix4Dbim cloud to be processed. You can use a 4G/3G SIM card or WiFi if available on site.
You will need a Micro SIM with data plan. A complete data collection will take approximately 70 pictures and use about 300MB of data. This is adjustable based on your need / preference.
By default, the camera will capture data once per day, every working day. Based on these settings we recommend: 300MB x 4 weeks x 5 working days per week = 6GB / month
We recommend a good 4G coverage. Test the signal strength on site before installing the SIM. A low signal can affect the reliability of the solution. Once you have selected the network provider, we can pre-configure your system.
The SIM card needs to be placed connector-side-up on the top of the module labeled “Telit”.
When enough images are collected, data is sent to the Pix4Dbim Cloud where it will automatically be processed.
The results should typically be available mid-morning after the system has captured the images in the early morning.
Accuracy is dependent on the height of the crane above the structure. As a guide, at 40m you get 1-2 cm accuracy.
Yes, but this would require the Pix4D Enterprise solution. Please contact us for more information.
The system and bracket weigh approximately 5 kg.
With Liebherr’s expertise, we use an airtight case, tailor-made to resist bad weather, dust and cold temperatures, and integrating a heating system to prevent system freeze and humidity.
Installing multiple systems on site is possible and will even create a wider overview of the jobsite. Images from multiple systems are automatically combined and processed.
Pricing is based on monthly subscription to the solution. For a monthly fee, you get the camera system (under full warranty) and unlimited data processing/access. It is also possible to purchase the system. Visit pix4d.com/store for full pricing information.
The system has a warranty against failure for the entire duration of the subscription period. In case of failure, the system will immediately be replaced.
Results are compatible and can be exported to BIM software for further analysis and BIM verification.
