KHD System – Diaphragm Wall Equipment

The new Casagrande KHD System thanks to the compact design, and the rotation system, the KHD is ideal for use in narrow spaces and to make diaphragm walls with different alignments

Introduction

The new Casagrande KHD System is a piece of equipment dedicated to the construction of diaphragm walls. 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

Thanks to the compact design, and the rotation system, the KHD System is ideal for use in narrow spaces and to make diaphragm walls with different alignments. Furthermore the modularity of the boom makes it possible to pass and build diaphragm walls even below existing structures engineering.

The heavy weight and the clamping force of the hydraulic bucket, the use of a quick free fall winch and the considerable power supplied by the diesel engine of the equipment allow you to successfully build the diaphragm walls even on difficult ground.

The design of KHD System makes it easy to use and comfortable for the operator. The XP series control systems and the precise instruments efficiently govern all machine functions and excavation operations.

Technical Innovation

PERFORMANCE AND PRODUCTIVITY

The Smart Power Management (SPM) is an intelligent engine power management system that improves performances and productivity of the machinery. The SPM system monitors the momentary power flows and immediately allocates the available power to the different jobs, so the operation function has always the maximum power available.

FULL LOAD SENSING TECHNOLOGY

The XP hydraulic power system uses the Full Load Sensing (FLS) technology. Unlike the common hydraulic
managing systems, the FLS pressurizes only the required amount of oil requested by users thanks to the back-action between pumps and distributors. It allows to manage the power demands and reduces dissipations, achieving up to the 25% of fuel saving (calculated on the basis of a theoretical working cycle).

SAFETY & TECHNOLOGY

The equipment has a very low sound emission level as a result of the of sound-absorbing materials and oil heat exchangers, designed for reducing the overall noise level. The layout of the machine and the wide openings of the canopy offer comfortable and easy access for inspection and maintenance. The machine conforms to the last international standards to guarantee the maximum safety of the operations.

FLEXIBILITY

The XP control system offers the following advantages for the operator and the supervision of the work: monitoring of all working function, diagnostic of the working systems to ensure the constant monitoring of the status of sensors and components, easy conversion in any drilling arrangement, friendly customization of working functions e.g. Remote rigs assistance, diagnostic, monitoring of working parameters.

Verticality Monitoring System

The instrumentation records verticality deviations to an accuracy of less than 0,1%. The DIALOG monitoring system includes a depth sensor on the winch and a NEMO sensor ﬁ tted on the grab. The NEMO measures verticality along the X and Y axis (via 2 inclinometers) and rotation along the Z axis (via gyroscope). The sensors transmit their measurements to the DIALOG which displays the trajectory followed by the grab in all three axis. The data is stored for downloading and post processing.
