          f it has been aquiet time for breakers
        
        
          lately in terms of new launches, this is
        
        
          because the sector has recentlyupdated
        
        
          to the latest technology, withnoise reduction,
        
        
          vibrationdampening andother advances such
        
        
          as automatic lubrication at the forefront of
        
        
          this.
        
        
          Thenext big thing is almost certainly
        
        
          waiting in thewings, or underwraps in the
        
        
          research anddevelopment laboratories of
        
        
          themajormanufacturers, so the lackof new
        
        
          models of late is nothingunusual. Therehave
        
        
          beenplentyof advances over the last few
        
        
          years.
        
        
          Looking further back, therewas an
        
        
          Breakermanufacturers
        
        
          have largely completed the
        
        
          move to a single line of
        
        
          silencedmodels and away
        
        
          from non-silenced units,
        
        
          and the latestmodels
        
        
          generally also sport vibration
        
        
          dampening.

          anniversary to celebrate last year, as
        
        
          September 2013 actuallymarked the 50th
        
        
          birthdayof thehydraulic breaker. This
        
        
          industry-transformingmomentwas claimed
        
        
          byAtlasCopco.

          Bautechnik, whichwas acquiredbyAtlas
        
        
          Copco in2002, developed the carrier-
        
        
          mountedhydraulic breaker and tookout a
        
        
          patent in1963. The firstmodel it produced,
        
        
          theHM400, attractedhuge interest at the
        
        
          Hannover fair in1967, withmore than2,000
        
        
          units sold.
        
        
          The aimwas to save time and labour in
        
        
          demolition andminingoperationswhere, at
        
        
          that time, pneumatic toolswerewidelyused.
        
        
          Of course, thenew conceptmeant that one
        
        
          personoperating a carrier-mountedhydraulic
        
        
          breaker coulddo the same amount ofwork as
        
        
          several operatorswithpneumatic tools.
        
        
          Today, hydraulic breakers are in
        
        
          widespreaduse and availableunder
        
        
          numerous brandnames around the globe.
        
        
          The technologyhas come a longway since
        
        
          its introduction, withmanufacturers now
        
        
          integrating advanced features such as high
        
        
          flowhydraulics, variable speed and anti-blank
        
        
          firing systems.
        
        
          Different parts of the industrywant
        
        
          different attributes from their equipment,
        
        
          and so, for example, the rentalmarket is
        
        
          not particularly interested in amass of

          compactmodels aremost indemand, and,
