Chassis
Assembly
The chassis is machined from solid 6061 T6
aluminum plate and two are required per assembly. The standard
finish is black anodized. When the logging truck hanging/guiding
system is properly balanced, the measure head assembly is
subject to very little stress. However, the Geo-Log system
is exceptionally strong and stronger then the older Gearhart
system. A generous amount of extra material has been left
at each end of the chassis to customize roller spacing for
exceptionally large cables. (i.e. 3/4 inch diameter.)
Guide
Rollers
Six guide rollers have been standardized at
1.5 inches in diameter. Standard material used is 17-4 SS
condition 1075 and the bearings are interchangeable with the
older system.
Measure
Wheel
The standard measure wheel is made of 17-4
SS condition 1075.

Pressure
Roller Assembly
The pressure roller assembly is a sub-assembly
of the chassis. The roller and it's shaft are made of 17-4 SS
condition 1075. The same seals (four required) used in the older
Gearhart system are used in the Geo-Log system.
The roller bearing (two required) is the same as the Gearhart
system and two snap rings hold the bearings and seals in place
at each end of the shaft. The bearing block may not be interchangeable
with the old system. However, all the seals and bearings of
this assembly have been made the same to help reduce inventory
for users who have both systems in the field.
The Geo-Log pressure roller assembly uses slightly heavier springs
than the older systems. This gives approximately 30 pounds more
pressure on average size cable. |
