Impact Energy Measurement of a Hydraulic Breaker
A hydraulic breaker for construction machinery generally used for the destroying and disassembling of buildings, crashing road pavement, breaking rocks at quarry and so on. So the measurement of the impact energy of a hydraulic breaker is very important thing to prove its capability to manufacturers and customers. In this study, the Methods of measuring the masses of whole machines, their equipment and components [2] This document establishes the terminology and content of commercial specifications for hydraulic breakers which are mounted as an attachment on a carrier, typically earth-moving machinery such as an excavator, backhoe loader, skid steer loader, and compactISO/DIS 16417(en), Earth-moving machinery ?

Assessment of Ground-Borne Vibration Impact on Nearby
High-level ground-borne vibrations generated by hydraulic breakers may adversely affect the surrounding environment and nearby underground facilities. Therefore, vibration impact assessment based on the estimation of vibration intensities on and below ground surface should be conducted before the commencement of any ground Impact energy, the main performance subject of hydraulic breakers, is required to evaluate value from consumers. This study proposes a neural network algorithm-based model to predict the impact energy of a hydraulic breaker without measuring it. The proposed model was developed using 1451 data points for various parameters as an Processes Free Full-Text Comparative Analysis of Machine

Breaker technology that protects equipment, operators
Moreover, no energy will be wasted during the rock breaking operation; this spares potential damage to the breaker, excavator boom and hydraulic circuits. Four digit-named breakers in the Montabert range from the V1800 to V4500 have a dual-frequency system. Two other digit-named breakers the V32 and V65 have an hydraulic breaker hammer noise is sm all, high security and flexibility is a better way to break the rock.

Hydraulic–mechanical coupling modeling by bond graph
The impact system of a high frequency rock drill drifter was modeled. The structure and working principle of the impact system are presented. A performance test system was built using the arm and the hydraulic source of excavator.A mathematical model was developed to analyze the nonlinear hydraulic–mechanical coupling performance for The power and versatility of high-impact breakers allow operators to perform a growing variety of tasks in mines and quarries. “Hydraulic breakers can be used for mass excavation or primary breaking,” Giroudon says. “They are effective for secondary breaking or ‘oversize breaking’ of blasted rock to sizes more manageable for crushers.Tips and technologies for hydraulic breaking Pit & Quarry

Investigating the Usability of Pyrotechnic Rock Breaker
Abstract This study describes two different methods only using "hydraulic hammer" and secondly "pyrotechnic rock breaker with hydraulic hammer" in combination used in Beige limestone quarry to find which one was the better method. The performance analyses were investigated by making in-situ measurements and observations such as Firstly, several technical specifications of various rock breakers mounted on 30 T class hydraulic rock breakers were evaluated. Also, the factors affecting cost and operation were identified and(PDF) The Development of a Telerobotic Rock Breaker

Hydraulic Rock Breakers Your Ultimate Guide to Breakers
Hydraulic Rock breakers are the oldest hydraulic attachments for excavators and diggers. The first serial manufactured rock breaker was the Krupp HM 400 in 1967 whilst the patent was secured in 1963. The most important thing is to have a reliable and powerful breaker.The potential affection of any construction, and especially historical sites, is of great concern for their long-term maintenance and stability. This study has determined the vibration behavior in poor-quality rock mass conditions generated by some of the most typical equipment used in construction: excavator, ripper, ripper vibrator, hydraulic Applied Sciences Free Full-Text Vibration Analysis and
