BEAMS
Trojan manufactures a wide range of beam axles to suit most applications. These axles are for use with leaf spring suspensions and include a straight beam. Drop beam and gullwing types. Braked and non-braked types are available. All axles can be supplied either galvanised or in bare metal form.
Depending on the capacity, axle beams are manufactured using either 40mm, 50mm or 65mm square hollow box section.
Beam axles are manufactured against firm orders only and are built to the clients' specifications. The following information is required when ordering these axles.
Note that hub equipment is to be ordered separately.
ORDERING FULL BEAM - QUESTIONS TO ASK
CARRYING CAPACITY
This is the maximum load including the trailer weight.
HUB EQUIPMENT
Are hubs to be braked or non-braked. Wheel drilling required.
FACE TO FACE MEASUREMENT
This is the measurement from the outside face of one hub to the opposite one. See A below.
SPRING MOUNTING CENTERS
This measurement is from centre to centre of the springs. See B below.
GULLWING AXLES
Measurements A & B are required plus C which is the required depth of the bend. This can be 60mm, 90mm or 120mm. See C below.
DROP BEAM AXLES
Measurements A & B are required plus D which is the required height of the drop. This can be 60mm or 90mm. See D below.
If you do not know the A and B details above then the following information is required:
• Chassis overall width. Minus 50mm. This gives spring centres
• Overall measurement outside the mudguards. Minus 30mm. This gives outside to outside of the tyres
• Inside & outside offset measurement of the wheels with tyres fitted. From this together with the mudguard measurement, the hub face to face can be calculated.
