INTRODUCTION
The Casagrande CB20 CFA is a more powerful and more economical piling rig, including modifications to the Smart Power Management (SPM)to gain significant fuel savings.
SPM – SMART POWER MANAGEMENT
The ability to intelligently manage engine power according to each specific function translates into greater
efficiency and productivity. A dedicated system continuously detects the required power, increasing it to its
maximum level only when necessary.
CFM – FLEET MASTER
The CFM system, developed and refined in collaboration with Vodafone, instantly detects any alarms or
malfunctions through an online platform accessible from PCs, tablets, and smartphones. Thanks to the standard
integration of Vodafone Business connectivity, real-time monitoring enables immediate intervention in case of
failures, significantly reducing downtime and optimizing the rig productivity.
CDR – DATA RECORDER (OPTIONAL)
The CDR monitoring system of the drilling process, allows for the detection and recording of the working
parameters. These data can be analysed and processed to generate detailed jobsite reports.
ENVIRONMENT AWARENESS
The latest-generation Stage V diesel engines reduce pollutant emissions and allow operation with both
low sulfur fuels and HVO (Hydrotreated Vegetable Oil)—a high-performance, low CO₂ emission fuel taken
from waste animal fats and used vegetable oils.
ERGONOMIC CABIN WITH HIGH VISIBILITY AND ACOUSTIC COMFORT
The cabin is designed to enhance operator comfort, reducing fatigue and increasing productivity while
ensuring excellent visibility. It is also soundproofed to ensure optimal acoustic comfort and equipped with
climate control system.
EASIER AND SAFER MAINTENANCE
The hydraulically lifting cover panels provide easy access to components for inspection and maintenance.
Additionally, the optional platforms and safety railings further enhance operator safety during these tasks.
AUTOMATED DRILLING WITH REAL-TIME PROGRESS VERIFICATION
The automated drilling functions available on the rig, in addition to simplifying its operation, allow the operator
to stay updated in real-time on the drilling process progress through an in-cabin display.
SIMPLIFIED AND CUSTOMIZED USABILITY
Each operator can create their preferred control system, avoiding potential operational errors and enhancing
the safety of the operations.
REMOTE CONTROL (OPTIONAL)
The remote control, which allows to perfectly manage all rig movements, enhances the operator’s safety during
loading and unloading operations from transport vehicles and during the setup phases for work.
OPTIMAL OPERATION IN EXTREME ENVIRONMENTS (OPTIONAL)
The rig can be equipped with a kit that ensures optimal machine performance and maximum efficiency even
in particularly cold environments. This includes hydraulic oil with stable viscosity and thermal properties,
a hydraulic oil preheating device, and an enhanced climate control system for the cabin.
