Rotary Actuator Applications: Mining, AWP, Excavators

Mining & rock excavation

Drilling jumbos, shotcrete, underground loaders

The heaviest wear environment we serve. Dust, shock loads and non-stop cycling are exactly where the helical design earns its keep — the sliding spline absorbs shock better than any gear rack.

Drilling rig boom positioning with rotary actuator — Bench drill boom swing and positioning — the classic heavy-duty HN30 job.

Concrete pump and shotcrete boom — Concrete placing boom articulation — smooth indexing under full hose weight.

Actuator position	Typical build	Machine types
Drill boom swing / positioning	HN30-73-180	Face drilling jumbos, bolters
Shotcrete nozzle manipulator rotation	HN30-19-360	Wet-mix shotcreting trolleys
Loader bucket / arm articulation	HN30-47-180	Underground LHDs

Machines seen in the field: Atlas Copco / Epiroc Boomer-type rigs, Sandvik DD-series drills, Furukawa and Junjin jumbos, Caterpillar and Komatsu underground loaders, Boart Longyear drills, domestic rigs by PRD, Sunrock and others.

Construction & earthmoving

Excavator attachments, where the growth is

India's excavator fleet is exploding and attachment penetration — tilt hitches, grabs, mulchers — is still in its infancy. That is the next five years of actuator demand. Our HN50 weld-base series replaces PowerTilt-type tilt mechanisms across 1–25 t carriers.

Excavator with tilting quick coupler — Tilting quick coupler on a midi excavator — HN50 weld-base actuator territory, 1–25 t carriers.

Excavator with rotary drum cutter attachment — Drum cutter and milling attachments need stiff, shock-tolerant rotation — straddle mounting only.

Actuator position	Typical build	Machine class
Tilt hitch / quick-coupler tilt	HN50 series	1 – 25 t excavators
Grab / clamshell rotation	HN20 / HN40	Material-handling fronts
Attachment swing (milling, crushing)	HN30	10 – 25 t carriers

Aerial work & specialty vehicles

AWP boom rotation, utility trucks, municipal fleets

Straddle mounting is the rule here — never cantilever a man-lifting boom. We supply HN20 builds with low-temp seals and steel balance-valve bodies for this duty.

Aerial work platform basket rotation — AWP basket and boom rotation — safety-critical duty, straddle mount, steel valve body.

Customer acceptance test of boom lift — Machine-level acceptance with the customer — every custom actuator is proven on the host machine before dispatch.

Actuator position	Typical build	Machine types
Boom / basket rotation	HN20-9-160	Boom lifts, scissor variants
Insulated arm articulation	HN20	Utility / line-maintenance trucks
Trash-container tip & rotate	HN20 / HN30	Garbage trucks, skip handlers

Industrial, energy & marine

Valves, solar, agriculture, ships, defence

Rear loader garbage truck bin tipper — Municipal rear-loader bin tip and rotate — high cycle counts, −20°C to +50°C duty.

Large butterfly valve with hydraulic actuator — Industrial butterfly valve operation — HN70 valve-control execution, any angle, zero internal leakage holding.

Application	Typical build	Notes
Ball / butterfly valve operation	HN70	Custom angles, valve-control execution
Solar tracker slew	HN10 / HN30	Photovoltaic single-axis trackers
Agricultural steering & header positioning	HN10 / HN20	Harvesters, steering axles
Deck equipment, hatch covers	HN30 with marine coating	Corrosion-protected build

FAQ

Choosing an actuator for your machine

Which actuator suits a drilling jumbo boom?

The HN30 series. Typical builds are HN30-73-180 for boom swing and positioning, HN30-19-360 for shotcrete nozzle manipulators and HN30-47-180 for underground loader articulation.

Which actuator is used for aerial work platform basket rotation?

HN20 builds such as HN20-9-160, with low-temperature seals and steel balance-valve bodies. Mount them straddle-style — never cantilever a man-lifting boom.

What rotates an excavator tilt hitch?

A weld-base helical actuator. The HN50 series replaces PowerTilt-type tilt mechanisms on 1–25 t carriers; grabs and clamshells use HN20 or HN40, and milling or crushing attachments use HN30.

Can a hydraulic rotary actuator operate a valve?

Yes. The HN70 valve-control execution turns ball and butterfly valves to any angle and holds position with zero internal leakage.

Are rotary actuators used on solar trackers and farm machinery?

Yes. HN10 and HN30 units slew photovoltaic single-axis trackers, and HN10 or HN20 units handle steering and header positioning on harvesters.

Do you build actuators for marine and corrosive environments?

Yes. Deck equipment and hatch covers use HN30 builds with a corrosion-protected marine coating.
