Excavator Cross Rotating Swivel Mount Bracket S30–S70 1–18 Ton Universal Attachment

Product Overview

The Excavator Cross Rotating Swivel Mount Bracket is a precision-engineered universal attachment mounting solution that provides a rigid, accurately dimensioned cross-pattern interface between the excavator's dipper arm and a wide range of attachments that require a centred, symmetrical mounting geometry — including hydraulic breakers, demolition hammers, compaction plates, vibratory rollers, plate compactors, and other attachments where the load must be distributed evenly across both sides of the mounting interface to prevent lateral stress, bracket deformation, and premature wear at the pin bore and weld joints. Available in seven standard configurations from S30 through to S70, covering excavator operating weights from 1 tonne to 18 tonnes, the E-CR cross bracket series provides a comprehensive mounting solution for operators, attachment manufacturers, and equipment dealers who need a structurally optimised bracket geometry for centred-load attachments across the full range of excavator classes used in construction, demolition, mining, and civil works applications.

The cross mounting geometry of the E-CR bracket is specifically engineered to address the structural limitations of standard straight-bottom pin-on brackets when used with attachments that generate high centred impact loads — most notably hydraulic breakers and demolition hammers, where the percussive force is transmitted vertically through the centre of the attachment body rather than distributed across the width of a standard bucket-style mounting interface. The symmetrical cross pattern distributes this centred load evenly across four contact points rather than two, significantly reducing the stress concentration at each individual mounting point and extending the service life of both the bracket and the attachment mounting lugs under the high-cycle impact loading generated during continuous rock breaking, concrete demolition, and hard ground penetration work. This structural advantage makes the cross bracket the preferred mounting solution for hydraulic breaker applications on excavators across all size classes from mini to large.

Every bracket in the E-CR series is manufactured from high-quality structural steel with ground mounting surfaces machined to a straight, flat bottom profile — ensuring full, even contact between the bracket mounting face and the attachment mounting plate without gaps, rocking, or misalignment that would concentrate load at contact edges and accelerate wear at the interface. The ground finish eliminates the surface irregularities inherent in flame-cut or plasma-cut mounting faces, providing a precision seating surface that maintains consistent attachment alignment throughout the service life of the bracket. All structural welds are performed using flux-cored wire welding for maximum penetration and tensile strength, with beveled weld preparation at all primary joints to ensure full fusion with the parent steel and resistance to fatigue cracking under the cyclic impact loads characteristic of hydraulic breaker and demolition hammer operation.

Seven standard model configurations cover the complete range of excavator classes from mini to large. The ME-CR-S30/S30 (300 × 300 × 67 mm, 14 kg) and ME-CR-S30/S30-150 (268 × 268 × 67 mm, 12 kg) serve 1–2 tonne mini excavators for compact breaker and compaction applications. The ME-CR-S40/S40 (372 × 372 × 71 mm, 30 kg) covers 2–3.5 tonne compact excavators, while the E-CR-S45/S45 (520 × 520 × 86 mm, 56 kg) addresses 4–6 tonne machines. The E-CR-S50/S50 (530 × 530 × 90 mm, 70 kg) serves the 6–8 tonne class widely used in urban demolition and road works, the E-CR-S60/S60 (575 × 575 × 110 mm, 109 kg) covers 10–14 tonne excavators for heavy demolition and quarrying, and the E-CR-S70/S70 (740 × 740 × 140 mm, 188 kg) serves 16–18 tonne large excavators deployed in major infrastructure demolition, mining, and large-scale rock breaking projects.

The E-CR Excavator Cross Rotating Swivel Mount Bracket is the preferred mounting solution for contractors and plant hire companies operating hydraulic breakers, demolition hammers, compaction plates, and other centred-load attachments on excavators across all size classes, attachment manufacturers supplying cross brackets as part of a complete breaker or compaction attachment assembly, and equipment dealers sourcing replacement or upgrade mounting brackets for customer machines requiring the cross geometry for specific attachment compatibility. Non-standard configurations, custom axle base dimensions, and alternative bracket geometries are available upon request for specialist attachment applications.
