Classic mechanical M3S or hydraulic H3S coupler

Reliability: Robust coupler

The mechanical M3S and hydraulic H3S coupler 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 M3S and H3S have functional play compensation between the tool and the quick fastener, while respecting the manufacturer’s kinematics. Which make it the essential coupler on the market.

Simple to use:

Only a few movements are needed to lock the tool.

For the mechanical coupler: Unlocking with the smart key unhooks the tool with a single action.

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 H3S 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 safety stop and on the 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 M3S and H3S couplers is green.

Compatibility:

The M3S and H3S couplers in Morin Original System are suitable for mini-excavators from 5.5 to 7.5 tons. They are equipped with an integral 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 M3S and H3S couplers, which are 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.

Double SAFETY SYSTEM:

The M3S and H3S couplers are compliant with standards EN474-1 and ISO13031:2016

The mechanical coupler M3S, like all the mechanical couplers in the Morin Original system, has a dual safety system comprising an:

• Automatically activated stop that prevents any risk of cam backward movement – patented system
• Cam equipped with the patented Form-lock system that prevents any risk of unlocking if the safety stop fails

The hydraulic coupler H3S, like all the hydraulic couplers in the Morin Original system,

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.
