Description
Overview:
Heavy duty 50mm tow ball on a two-bolt flange plate, finished in silver. Bolts to any standard flange towbar drilled at 90mm centres and accepts all UK and EU 50mm ball couplings. Rated at 350kg vertical load, making it suitable for heavier noseweight trailers than the standard pattern. Type approved to UN/ECE Regulation 55. Supplied bulk packed. Mounting bolts are ordered separately.
Specification:
- D-value: 17.2kN
- S-value (vertical load): 350kg
- Ball diameter: 50mm
- Fixing centres: 90mm
- Mounting: 2 x M16 bolt holes
- Plate width: 130mm
- Overall height: 120mm
- Finish: silver
- Approval: UN/ECE Reg 55 (E11 55R-0110512)
- Maypole part number: MP500B
Fitting:
Use BS3692 grade 8.8 high tensile bolts with lock washers. Torque to 240Nm, then re-check after first use and at regular intervals thereafter.
Towing Capacity:
Maximum braked trailer weight derived from the D-value:
- Behind a 3,500kg vehicle: 3,510kg
- Behind a 7,500kg vehicle: 2,280kg
These are coupling limits only. The lowest of the coupling limit, the towing vehicle's plated towing limit, the trailer's gross weight and the driver's licence entitlement applies. Centre-axle trailers are rated on Dc and V-value rather than D.
Typical Applications:
Plant, tipper and twin axle trailers carrying higher noseweights, on vans, pick-ups and light commercials in daily site use. The silver equivalent of the black MP5003B, sharing the same approval.
