Hydraulic hammer sets ‘D’ productive standard

Caterpillar has introduced the H65Ds hydraulic hammer, which will replace the H63 and H63s models. “The release of the H65Ds hammer is an extension of the successful line of D-series hammers [and is] designed with the customer�s satisfaction in mind,� said Jan Willem van den Brand, commercial manager, Caterpillar Impact Products. “We are pleased that our new hammer adds more productivity value to cater to the needs of our customers.� The H65Ds has been designed using six sigma tools, with a 40% reduction in the number of parts used in the hammer compared to the H63s. Disassembly and rebuild times have been reduced by 50%. The lower bushing, upper bushing and thrust ring have all been incorporated in a three-in-one service part, which allows easy access and visibility of the entire tool guidance system for quick inspection in the field. According to the firm, the performance of the H65Ds hammer sets it apart from other hammers in the 270kg weight range and puts it in a class of it�s own. Both the oil acceptance range and operating pressure have been increased, which has resulted in an overall improvement in productivity of over 15% compared to the H63/H63s hammer. The hammer comes complete with mounting groups for 303CCR, 303.5CCR, 304CCR and 305CCR machines and Caterpillar pin grabber quick couplers, therefore eliminating the need for a mounting bracket. For machines with a dedicated quick coupler, or skid-steer and multi-terrain loaders, mounting adaptor plates are available.
