How To
1. Pick the bottom drive for frames with blocked sides
Bottom drive actuation routes the linkage beneath the body when side or top routing is impractical on off-road vehicles and construction machinery.
2. Choose single- or double-stage by door travel
Single-stage covers short pulls; double-stage adds travel for heavily gasketed sealed doors on generator sets and specialty enclosures.
3. Route dual-rod actuation where one rod is not enough
Vertical or dual-rod actuation options spread the operating force on wide doors; pick the rod layout that matches the hinge and seal geometry.
4. Use the shock-absorbing build on vibrating machinery
The shock-absorbing configuration suits doors that see continuous vibration on construction and off-road equipment, damping the closure and protecting the mechanism.
5. Stay inside the 14,000 N ceiling
Maximum load capacity is 14,000 N; size the door and gasket for working loads comfortably below it so locking retention stays consistent.
