Installation
1. Preparation
1.1 Check the slew drive for physical damage.
1.2 Clean supporting surfaces
2. Mounting Bolts
As the gearbox manufacturer, we do not supply, warrant or recommend the mounting fasteners used. Please take great care in specifying this item which will attach our product to yours.
Prescribed sizes, number and quality grades shall be used.
Grip ratio (grip length to diameter of bolt) shall be observed, from minimum ≥1.5 to maximum ≤2.
Bolts with a fully threaded shaft should be not permissible.
Slew drive function, lifespan, and durability of the bolt connection are affected in case of non-compliance.
Use flat washers of appropriate size and strength choice of tightening torques so that the permissible interfacial pressure is not exceeded.
Mounting bolts are in normal cases adequately secured by correct preloading.
Notice: Use of split rings, split washers, etc. not permissible.
