Hydraulic H2S tiltrotator

Multi-function capability

The hydraulic H2S tiltrotator ^{nox inside} is the most complete coupler in terms of functions, and is used on hydraulic excavators from 3.5 to 5.5 tons.

The 360° rotation and the ± 50° inclination allow the tool mounted on the coupler to move in all directions simultaneously.

Our tiltrotator is proven and is extremely compact.

Unlike other tiltrotators on the market, the coupler has no protruding parts, thus allowing work in narrow trenches or in a forestry environment. This also reduces maintenance and the risk of breakage.

Inclination

The patented inclination function is based on an elliptical piston and a helical gear system to provide the inclination function. This design allows a low construction height, which limits the loss of digging force for all the tools mounted on the tiltrotator, with no external actuators.

Tiltrotator with actuators	Tiltrotator nox inside without actuators
Actuators may be damaged by contact with earth, stones or branches	Narrow width, compact design, with robust construction
Bearing bushes need regular lubrication, which is additional maintenance	Little maintenance required, rotation elements in oil bath, few lubrication points
Inclination angle limited and loss of rotation torque as a function of the inclination angle	Constant torque inclination, with no loss of performance, irrespective of the inclination angle
	Narrower width in the trench : on average, 120mm less (depending on the model)

Orientation

The 360° orientation ring operates in a completely sealed oil bath, with no maintenance required for a long working life.

Construction

The tiltrotator has 2 integral hydraulic control functions for accessories. The hydraulic revolving joint is standard equipment and the electrical revolving joint is optional.

A fully integral tube gripper is also available as an option.

DF4 Control system

Control system DF4 needs two double action hydraulic circuits. Rotation and inclination can be executed simultaneously with the machine’s original proportional control system.

The DF4 cab control unit can divert the tilt function to:

• Up to two extra hydraulic functions, as selected, to feed hydraulic accessories

or

• the hydraulic quick hookup.

Machine requirements for DF4

• High rate auxiliary line with proportional control, to control inclination and the extra functions
• Medium rate auxiliary line with proportional control, to control rotation
• An ON/OFF button per extra function is required on the existing levers, to control their switching. If needed, ACB+ offers supplementary buttons as an option.

Compatibility:

The hydraulic H2S tiltrotator ^{nox inside} in the Morin Original System is suitable for mini-excavators from 3.5 to 5.5 tons. It is equipped with an integral lifting ring, designed to be used with the shackles recommended by ACB+ (except sandwich versions).

All the tools in the Morin Original system M2 can be used on the hydraulic H2S tiltrotator ^{nox inside}, which is pinned onto the machine with the original pins.

The tiltrotator ^{nox inside} is also available with the Nordic S and Verachtert CW systems.

Simple to use:

Only a few movements are needed to lock the tool. The same goes for unlocking; simply press the control unit in the cab to unhook the tool. In the case of a hydraulic problem, the powered hydraulic H2S tiltrotator ^{nox inside} 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 powered hydraulic H2S tiltrotator ^{nox inside} is identified by the colour yellow.

Double SAFETY SYSTEM:

The hydraulic H2S tiltrotator ^{nox inside} is compliant with standards EN474-1 and ISO13031:2016

Like all the hydraulic couplers in the Morin Original system, the hydraulic H2S tiltrotator ^{nox inside} 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.

H2S Tiltrotator nox inside

* according to standard ISO6015:2006 Methods of determining tool forces

(*): nominal flow with 1.5 bar pressure drop
(**): maximum recommended flow rate
(***): Standard quick connector compliant with ISO 16028

Note: A tube gripper is optional on tiltrotators.

Connectors on the coupler are optional:

Without tube gripper: choice of

• 1 double-action line (channels A and B)

or

• 2 double-action lines + drain (channels A/B and C/D + drain)

(not available with tube gripper fed by channels C and D).
