The sector plate is a critical mounting bracket used in the front axle assembly of a forklift.
Its primary function is to serve as the structural link between the drive axle housing and the truck
frame or the mast (the lifting structure).
Material Used:
The component is typically a cast steel, designed with a central hole for articulation and several
mounting holes along its curved edge for bolted connections.
Its unique shape allows the axle to pivot slightly or absorb torsional stresses, preventing damage
from frame deformation during operation.
Their Feature& Functions:
Rotatable Installation:
In many designs, the sector plate is not rigidly fixed but rotatable on the axle housing. This facilitates
easier assembly and simplifies maintenance by enabling a 360-degree rotation during servicing.
Precise Alignment:
It is often used in conjunction with locating pins and dowel holes during the welding process. This
ensures high precision in the angular alignment between the axle housing and the sector plate without
needing complex tooling.
Versatility:
In some configurations, the sector plate works with a bearing cap to create a mounting structure that
is dimensionally compatible with both "hard" and "soft" connection systems, allowing for standardized
frame design across different forklift models.
