Classic hydraulic coupler H5S

M5 For carriers from 10 to 15t

Compliant with standards EN474-1 and ISO13031:2016

For your peace of mind, ACB+ is permanently involved in standardisation processes and actively contributes to European committees that draft standards. Thus our products comply with the latest versions of the regulatory texts.

Thus, ACB+ always offers the best performance with optimum safety for all its couplers, in particular by equipping them with a dual safety system that is protected by several patents.

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.

Reliability: Robust coupler

The hydraulic coupler H5S is a high-strength steel casting which guarantees long periods of utilisation of the quick fastener. This hydraulic coupler has an enclosed structure, for optimum protection of the double action actuator. Like all the couplers in the Morin Original System, the H5S has functional play compensation between the tool and the quick fastener, while respecting the manufacturer’s kinematics.

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 H5S 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 colour applied to the H5S coupler is blue.


The H5S coupler in Morin Original System is suitable for excavators from 10 to 15 tons. It is equipped with two integral lifting rings, designed to be used with the shackles recommended by ACB+.

All the tools in the Morin Original system H5, can be used with the H5S coupler, which is pinned onto the machine with the original pins.

Additionally, ACB+ offers all the components necessary to equip the machine for the control of the hydraulic coupler in strict compliance with the applicable standards. These components are available individually or in a complete kit. Thus, it is possible to rationally pre-equip your machine, for trouble-free utilisation of your equipment in complete safety.

The H5S coupler is compliant with standards EN474-1 and ISO13031:2016

Like all hydraulic couplers in the Morin Original system, the H5S coupler 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.
