The Nice Robus 400 (model RBS400) is an Italian 24V sliding gate motor. It takes gates up to 400 kg and 8 metres. One number decides whether it suits your gate, and it is not the 400 kg. It is the push force your gate needs, which must stay under 75 N. We stock the complete kit in Al Khuwair for OMR 125.000 and fit it across Oman.
Nice Robus 400 gate weight is not the limit that matters
Nice publishes two thrust figures for this motor. Start peak thrust is 510 N, or 15.4 Nm. Rated working thrust is 150 N, or 4.5 Nm.
Nice’s manual tells the fitter to measure the force needed to move the gate along its whole path. That force must stay below half of the rated figure, so 75 N. It is roughly 7.6 kg on a hand scale.
Sand in the track, a bent rail or a worn wheel raises that force without changing the weight. Many seller pages print 400 N as the motor’s power. That is not Nice’s working figure.
Nice Robus 400 in Oman heat, dust and salt air
Nice scores wear in a severity index, and the motor is rated for residential use. Heat above 40°C or humidity above 80% adds 10%. Dust and sand add 15%. Salt air adds 20%.
| Gate | Weight and length | Heat, dust, salt | Total |
|---|---|---|---|
| 200 kg, 4 m leaf | 30% + 10% | 45% | 85% |
| 400 kg, 4 m leaf | 60% + 10% | 45% | 115% |
Nice says an index above 100% is beyond the limit, and calls for a larger motor. A light gate near the coast sits inside the limit. A full 400 kg gate with all three Oman factors does not, so step up to our Nice Robus 600. Tell us your gate weight and we will check.
Cycles per hour and the daily limit
| Gate length | Cycles per hour |
|---|---|
| Up to 4 metres | 35 |
| Up to 8 metres | 20 |
The daily limit is 80 cycles, and the longest continuous run is 7 minutes. A villa fits well inside these limits. A shared entrance or a busy yard does not.
Nice Robus 400 RBS400 or the earlier RB400
| RBS400, this kit | RB400, earlier | |
|---|---|---|
| Limit switch | Magnetic | Electromechanical |
| Control unit | MCU1 | RBA3 |
| Radio receiver | Built in | Plug in |
| Start peak thrust | 510 N | 400 N |
| Standby power | 0.4 W | Not listed |

Spare boards and receivers differ between the two, so quote the code on your motor label when you order parts. This kit is the 230V version, which suits Oman. Nice also makes 120V and 250V versions, so check the label.

What is included in the Nice Robus 400 kit
- One Nice RBS400 24V motor with integrated MCU1 control unit
- Two Nice MYGO4 four channel remote controls
- One pair of Nice EPMB BlueBUS photocells
- One Nice ELDC LED flashing light with antenna
- Four nylon racks, one metre each
- One push button and one safety sign
Quoted separately: installation, foundation concrete, extra rack and the optional PSS124 back up battery. See remotes and accessories for more. Nice rates its nylon rack for gates up to 500 kg, above this motor’s limit. A gate longer than 4 metres needs more rack than the kit holds.
Installing a Nice Robus 400 sliding gate motor in Oman
Our engineer starts with the push force test and checks the track and wheels. The motor sits on a foundation plate cast level in concrete. We set the pinion 1 to 2 mm clear of the rack.
Then we fit the magnetic limit bracket and wire the photocells. BlueBUS carries up to 15 devices on two wires, and the control unit learns the gate length on its own. A two leaf gate uses two motors, one Master and one Slave. The key release moves the gate by hand in a power cut.
Nice asks for service within 6 months, or 2,000 manoeuvres, since the last visit. At 30 cycles a day, that is about every two months. We book the visit for you.
Sliding gate motor installation for villas across every governorate
We install in Muscat, Sohar, Nizwa, Salalah, Sur, Duqm and every other governorate. See our sliding gate motors, the Nice range, gate spare parts or our installation service.
Common questions
Can the Nice Robus 400 move a 400 kg gate?
Only if the push force stays under 75 N. In Oman heat, dust and salt, Nice’s wear index puts a full 400 kg gate past its limit. Send us your gate details and we will tell you if it suits.
Is this the Nice RBS400 or the RB400?
This kit is the RBS400, the newer generation. It has a magnetic limit switch and a built in receiver. The earlier RB400 used the RBA3 board.
How often does the Nice Robus 400 need servicing?
Nice asks for service within 6 months or 2,000 manoeuvres, whichever comes first. We can book the visit.
What does the Nice Robus 400 kit cost?
OMR 125.000 for the kit with motor, photocells, two remotes, flashing light and 4 metres of rack. Payment is cash on delivery. Installation is quoted separately.
