Manual & Clutch Gearboxes for Fence & Gate Machinery

Self-locking hand-crank worms and clutch-engage worm drives for fence, gate, and barrier machinery — built to hold position safely when power or the operator stops.

Fence, Gate & Barrier Machinery

Hand-Crank and Clutch Worm Drives That Hold Position

Fence and gate machinery needs two things catalogue boxes often miss: a safe hold when the operator lets go, and a way to engage or free the drive for setup. Anand Gears builds manually operated self-locking worm gearboxes (high ratio, hand-crank input) and clutch / lever engage-disengage worm units for OEMs in this segment.

Manual worm, high ratio (e.g. 100:1) for self-locking hand operation
Foot-mounted housings with vertical hand input / horizontal output
Clutch and engage/disengage lever variants (LH or RH)
Hollow clutch input and special D-mounting legs where required
Adaptable family specials with coupler and keyway-bored outputs
All critical dims in millimetres on shop drawings

Product Types

Manual, Lever, and Clutch Configurations

Manually operated worm

High-ratio foot-mounted worm with hand-crank input. Self-locking holds the gate or fence mechanism when the handle is released — no separate brake for many designs.

Engage / disengage lever

Worm units (e.g. 25:1 class) with a side lever that couples or frees the drive for machine setup and emergency freewheeling.

Clutch worm gearbox

Coupler, keyway-bored output, and clutch geometry integrated with the worm housing — used where motorised and manual modes share one gearbox.

Hollow clutch input

Hollow input shaft clutch designs for compact motor interfaces, with special mounting legs when the OEM frame is non-standard.

FAQ

Manual & Clutch Gearboxes for Fence & Gate Machinery — Common Questions

Why use a high ratio for manual fence drives?

Higher worm ratios (for example 60:1–100:1) are more reliably self-locking, so the load stays put when the operator stops turning the handle.

Can the clutch lever be left-hand or right-hand?

Yes. Lever side and packaging envelope are set per machine. Provide a sketch showing free space around the housing.

Do you reverse-engineer competitor clutch boxes?

We manufacture drop-in replacements matched to mounting and shafts from samples or drawings — without needing the original brand nameplate for the build.

Specify a Manual or Clutch Drive

Share ratio (often 25:1 or 100:1 class), hand-input orientation, clutch lever side (LH/RH), output shaft ends in mm, and a sketch or photo.
