INTRODUCTION
The Casagrande CB20 is a machine dedicated to giving the specialist contractor equipment to perform large diameter rotary and CFA piling. It is the result of research and innovation based on over 50 years of experience and success of the company in the field of foundations and geotechnical engineering
Due to the high torque of the rotary head, up to 204 kNm, and to a powerful winch, the CB20 is able to rapidly drill deep and large piles. The crowd winch with a line pull of 343 kN and the stroke of the rotary head of 15.5 m will drive casings deep into the ground with extreme accuracy.
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 sulphur 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
