Hydraulic H6S rotating coupler

M6 For carriers from 15t to 18t

For carriers from 15t to 18t

Compliant with standards EN474-1 and ISO13031:2016

As a major designer and manufacturer of tools and quick fasteners, ACB+ designs its couplers in the respect of the geometries imposed by the machine manufacturers. Thus, machine performance is entirely conserved.

The rotating coupler has a broad range of applications. It provides a multi-function capability and the reversibility of all compatible tools.

Using the 360° rotation, do up to 80% of the work of a tilt-rotator for a much lower cost. The orientation function is available in the hydraulic coupler version and allows very precise working, particularly for roads and networks.

  • 360° rotation through the hydraulic power unit, and the wheel and worm gear.
  • Hydraulic and electrical (option) revolving joints are available to accept all types of tools.
  • Extremely simple to install due to the use of an ancillary line for the rotation (proportional control strongly recommended)
  • Compact and sturdy construction for occasional use of a HRB.
  • Sealed casing for total protection of the hydraulics.
  • Compatible with all tools in Morin Original System the original S, CW and SW hookup systems

Description

Functions:

Did you know that an rotating coupler offers even more possibilities than an inclinable coupler?  This same coupler does up to 80% of the work of a tilt-rotator for a much lower cost!

Compared with a conventional coupler, the rotating coupler offers a time saving of 10% in excavation, 30% in networks and 50% in construction, while also eliminating manual work.

It’s the perfect solution for your work site multi-function requirements. It has a broader range of utilisation than inclinable couplers and provides the required precision, particularly for roads and networks applications: complex form embankments, tipping and filling of trenches, mound working, rockfilling, moving pallets, working around a pipe, sorting, compacting, hydraulic hammer, etc.

Manoeuvrable and practical

Driver familiarisation with the hydraulic H6S rotating couplers is simple and quick due to their compact design and their driving through a single hydraulic function in the cab. The worm gear system provides high precision and 360° rotation. The rotating coupler also provides reversibility for all your accessories.

No complex conversion or extra equipment is required to install the hydraulic H6S rotating coupler. Most machines have 2 auxiliary lines and the line with the highest flow rate is kept to feed tools such as the HRB.

In fact, the HRB can be used occasionally, thus avoiding sandwich assemblies.

The hydraulic H6S rotating coupler is equipped with a hydraulic revolving joint, the flow rates of which allow a hammer or a gripper to be used (standard for hydraulic coupler and, on option, an electrical connection.

Reliability:

The hydraulic H6S rotating couplers are compliant with standards EN474-1 and ISO13031:2016

The hydraulic H6S rotating couplers have a compact design, thus maintaining the maximum performance of the machine.
They are equipped with a specifically designed and sized worm and wheel coupling protected by a high resistance monobloc housing, fully sealed for a longer life. The components are carefully selected for their mechanical robustness and their resistance to wear, allowing the occasional use of a hydraulic breaker.

Simple to use:

Only a few movements are needed to lock the tool.

For the hydraulic coupler:  Unlocking by simply pressing the control unit in the cab unhooks the tool. In the case of a hydraulic problem, the H6S coupler can be unlocked using a standby key, thus providing service continuity

Easy identification of module:

The module is easily identified through the use of a colour code on the casing and on the standby unlocking key. This advantage is particularly appreciated in multi-module installations.

The module ident. is also engraved the couplers and tools.

The rotating hydraulic coupler H6S  is identified by the colour violet.

Compatibility:

The hydraulic H6S rotating coupler is suitable for mini-excavators from 15 to 18 tons. It is equipped with a lifting ring, designed to be used with the shackles recommended by ACB+.

All the tools in the Morin Original system M6, can be used with the rotating hydraulic coupler H6S, which is pinned onto the machine with the original pins.

The rotating hydraulic coupler H6S is also available with the Nordic S and Verachtert CW and SW systems installed.

The universal scraper was specifically developed for optimum rotation and the HRB may be used occasionally.

Double SAFETY SYSTEM:

The hydraulic H6S rotating couplers are compliant with standards EN474-1 and ISO13031:2016

Like all the hydraulic couplers in the Morin Original system, the hydraulic H6S rotating coupler has a dual safety system comprising an

  • Double-action hydraulic actuator, permanently pressurised, to hold the cam in the locked position
  • Cam equipped with the patented Form-lock system that prevents any risk of accidental unlocking

The overall system is equipped with an indicator that is visible from the cab, to visually confirm proper locking.
