Hydraulic tilt coupler H3S with actuator

M3 For carriers from 5.5 to 7.5t

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 tilt coupler with actuator is an economic solution that is extremely robust, thus accepting the utilisation of an HRB. Its ± 45° inclination allows multi-function tools to be used.

Advantages of the tilt hydraulic inclinable coupler H3S with actuator in the Morin Original system

  • The ± 45° inclination is provided by a fully protected, double-action hydraulic actuator
  • Inclination torque remains virtually constant over the entire inclination range
  • Extremely simple to installation, due to the use of an ancillary line for the inclination (proportional control strongly recommended)
  • The hoses are contained, thus providing a very compact unit for working in narrow trenches
  • Occasional use of an HRB
  • Tools in the Morin Original system are selected without leaving the cab

Functions: Double action actuator

The tilt hydraulic coupler with actuator offers ± 45° inclination for all your accessories in the Morin Original system and is ideal for creating and maintaining embankments.

This tilt hydraulic coupler has an equal-section double action hydraulic actuator, protected by integral valves, providing precision and strength in all your finishing work.

The actuator, coupled with an extremely compact crank system, gives a virtually constant inclination torque over the entire inclination range.

Installation is easy and quick due to the use of a simple ancillary line from the excavator.


The tilt hydraulic coupler H3S with actuator, in the Morin Original System is suitable for mini-excavators from 5.5 to 7.5 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 M3, can be used with the tilt hydraulic coupler H3S with actuator, which is pinned onto the machine with the original pins.

An HRB can also be used occasionally on this coupler.

Reliability and compactness

In addition to the robust structure and play compensation offered by all ACB+ couplers, the entire actuator and crank system are protected by a casing, which is reassuring, particularly when working in narrow trenches.

The heavy duty articulation bearings are in high-strength treated steel, allowing the occasional use of a hydraulic hammer. In addition, the system is protected by robust mechanical stops at its travel limits.

Simple to use:

Only a few movements are needed to lock the tool. And similarly for unlocking by simply pressing the control unit in the cab, which unhooks the tool. In the case of a hydraulic problem, the tilt hydraulic coupler H3S 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 tilt hydraulic coupler H3S with actuator is identified by the colour green. 


The tilt hydraulic coupler H3S with actuator is compliant with standards EN474-1 and ISO13031:2016

Like all the hydraulic couplers in the Morin Original system, the tilt hydraulic coupler H3S with actuator has a dual safety system, comprising a:

  • 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.
