Strength coupled with safety

SAF-Holland is keen to promote its V.Orlandi E551BOM 50mm tow coupling as the strongest in the market – with a D-Value rating of 330kN – yet also the lightest at 42kg. It also features the highest vertical or S-Load rating of 2,500kg.

Acquired by SAF-Holland in 2018, the V.Orlandi range covers a variety of different models of trailer couplings, but the core volume product in the Australian market is the E551BOM.

According to SAF-Holland, the E551BOM has been sold in Australia for many years and is used by a number of major fleets in the field.

Key features of the product include a 50mm diameter pin with metal wear pad and mechanical lock, providing a 330kN D-Value rating.

Ensuring the pin cannot be inadvertently disengaged, there is a safety mechanism on the left of the unit that needs to be released before the handle can be moved.

The unit uses an ISO (International Standard) bolt pattern of 160mm x 100mm for mounting to the truck chassis which means it is interchangeable with other brands of tow couplings in the market.

Another particularly useful feature of the E551BOM coupling in tipper and dog applications is the ability to couple and uncouple the trailer at any drawbar angle up to the 1050 ‘jack-knife’ position.

The mechanism box is fully sealed to minimise the ingress of dust and moisture which can cause the pin to bind, thus hindering pin release.

According to SAF-Holland, the encapsulated locking mechanism also makes the replacement of the pin an easy five-minute job, as there are no loose components and disassembly of the entire unit is not required.

Further to this, the bell-mouth is a separate bolt-on casting and can be easily and quickly replaced in the event of damage.
SAF-Holland says spare parts are stocked by all major truck and trailer wholesalers Australia-wide.
A number of optional features can be added to the product including an externally mounted red and green indicator light display which confirms whether the pin is engaged or disengaged and a jack-knife indicator with acoustic warning mounted in the truck’s cab.

There’s also the option of an air-release for the pin to maximise operating time and minimise the risk of operator injury caused by manual pin release. This includes an on-box safety indicator that verifies correct pin engagement.

According to SAF-Holland Australia National Aftermarket Manager, Phil Crosbie, the V.Orlandi E551BOM tow coupling has a proven track record in a variety of applications under harsh Australian conditions.

“It’s a high-quality product made in Italy with among the highest load ratings and lowest weight in the industry,” Phil says. “This is an important factor given that operators are always chasing lighter tare weights in order to maximise payload capacities.”

Fast Fact
V.Orlandi tow couplings is one of the key brands in the SAF-Holland commercial vehicle component portfolio. The V.Orlandi E551BOM coupling is among the strongest and lightest of its kind in the industry.
