All Fields Must Be Filled Out

Hoist Drive

AFC and AWL series hoist winch gearboxes powering lift capacities from 6 to 40+ metric tons across CTT and CTL crane models. Critical drives rebuilt to OEM torque and drum-speed specifications.

Slewing Drive

SSR, SCC, SVF, and RCC series slewing ring gearboxes controlling crane rotation on CTT flat-top and CTL luffing jib models — precision drives rebuilt to exact rotational speed and braking specification.

Luffing Drive

LFC series luffing winch gearboxes controlling jib angle on Terex CTL luffing cranes. Continuous-duty drives with high shock loads that demand expert rebuild and full load testing before return to site.

Travel & All Series

Travel drive gearboxes, service winch units, and all legacy Terex Comedil configurations including discontinued models. Full in-house component manufacturing for parts no longer in OEM supply.

When Every Hour of Crane Downtime Costs You

Is Your Terex Comedil Gearbox Down?

Terex Comedil tower cranes — the Italian-engineered CTT flat-top and CTL luffing jib series used on construction sites worldwide — rely on precisely engineered hoist, slewing, and luffing gearboxes to lift and position loads of up to 40 metric tons at heights reaching 84 meters. When any one of these drives fails, the crane is grounded and project timelines are immediately at risk.

Specialty Gear Drives provides the fastest certified repair path for any Terex Comedil crane gearbox. We disassemble, inspect, and manufacture replacement components on-site to exact OEM torque and speed specifications — getting your Terex Comedil crane back online at a fraction of the cost of a new unit or factory exchange.

Root Cause Analysis

Common Terex Comedil Gearbox Gearbox Failures

Terex Comedil crane gearboxes operate under some of the most demanding duty cycles in construction — lifting maximum loads repeatedly while exposed to weather, vibration, and thermal cycling. Our diagnostics team pinpoints every failure mode before repair begins.

Hoist Gear Set Wear

AFC and AWL hoist drive gear sets develop surface fatigue and tooth wear under sustained maximum-load lifts and repeated dynamic loading cycles. Worn hoist gearing causes drum speed variation, reduced lift capacity, and eventual catastrophic failure.

Bearing Failure

High radial and thrust loads in Terex Comedil hoist and slewing drives accelerate bearing wear — especially under repetitive shock loading. We replace all bearings with Timken-certified equivalents using liquid nitrogen thermal installation.

Slewing Drive Wear

SSR and SCC series slewing gearboxes sustain continuous wear from repetitive rotational cycling and wind-induced loads. Worn slewing drives cause jerky or uncontrolled rotation and compromised load positioning accuracy.

Seal Failure & Contamination

Crane gearboxes are exposed to weather, dust, and construction site contamination. Degraded seals allow oil loss and abrasive ingress — accelerating internal wear across all reduction stages. All seals replaced as standard in every rebuild.

Luffing Gearbox Damage

LFC luffing winch gearboxes sustain high dynamic shock loads from jib angle changes under loaded conditions. Worn or cracked luffing gearing requires immediate expert rebuild to restore safe and controlled jib positioning.

Housing Bore Wear

Bearing migration under high crane operating loads causes housing bore wear in Terex Comedil gearbox castings — leading to misalignment and rapid internal deterioration. Precision line-boring restores all critical bore diameters to OEM specification.

Thermal Overload

Continuous-duty hoist cycles in hot climates or with degraded lubrication push Terex Comedil drives beyond thermal design limits. We restore all heat-damaged components and apply protective housing coatings to reduce future thermal stress.

Shaft & Pinion Damage

Shock loads from abrupt hoist stops and emergency braking cycles cause keyway wear and surface deterioration on hoist and slewing drive shafts. Components beyond reconditioning are manufactured new to OEM hardness and dimensional specification.

Our Proven Method

The Specialty Gear Drives Repair Process

Every Terex Comedil crane gearbox receives our complete six-step rebuild — including specialized procedures for AFC hoist drives, SSR/SCC slewing gearboxes, and LFC luffing winch units across all CTT and CTL crane series.

Free Pickup & Intake

We arrange no-cost nationwide freight pickup. Your Terex Comedil gearbox arrives and is immediately logged, assigned to a certified crane drive technician, and full disassembly begins the same day — no delays.

Industrial Cleaning & Inspection

All components — hoist gear sets, slewing pinions, shafts, bearings, and housings — are cleaned in our industrial parts washer and individually measured against Terex Comedil OEM torque and clearance specifications.

Root Cause Documentation

We identify and document exactly why the Terex Comedil drive failed — overloading, lubricant contamination, seal failure, or fatigue wear — ensuring the root cause is corrected and not repeated after repair.

In-House Component Manufacturing

Worn Terex Comedil gears, shafts, and precision components are manufactured on-site to OEM dimensional and hardness specifications — including legacy Comedil series no longer available through standard OEM supply channels.

Rebuild & Bearing Upgrade

Reassembly uses Timken-certified bearings installed via liquid nitrogen thermal process — never pressed. All new seals, gaskets, and a high-temp polymer housing coating complete the rebuild with all preloads set to Terex Comedil OEM specification.

6-Hour Load Test & Certification

Every rebuilt Terex Comedil gearbox runs a full six-hour load test monitoring vibration, temperature, and leak-tightness before certification under our 24-month production warranty — ready to return to job site service.
