Mechanical Power Transmission Products for Cranes Industry

In the Cranes industry, power transmission components must perform reliably under the most demanding duty cycles — from the high shock loads of load pick-up and dynamic braking in hoist drives, to the continuous high-inertia reversal loads of slewing and travel mechanisms. Safety is paramount: a coupling failure on a ladle crane or harbour crane carries severe operational and safety consequences.

At Nu-Teck, we provide high-performance Gear, Jaw, and Disc Couplings engineered for the full range of crane types — from workshop EOT cranes to heavy-lift harbour and foundry cranes.

Power Transmission Products for Cranes industry
Applications in the Cranes Industry
Overhead & EOT Cranes
Application Nu-Teck Coupling Nu-Teck Advantage
EOT Crane Long Travel (LT) Drive Gear Couplings (Spacer / Ext. DBSE) Connects motors to wheel gearboxes across the bridge — spacer type accommodates
shaft misalignment from bridge deflection under load and allows wheel or
gearbox maintenance without disturbing the motor.
EOT Crane Cross Travel (CT) Drive Gear Couplings / Jaw Couplings Drives trolley travel along the bridge girder — jaw couplings provide maintenance-free,
vibration-damped operation for the frequent start-stop cycles of cross-travel duty.
EOT Crane Hoist / Hoisting Mechanism Gear Couplings (Heavy-Duty) Transmits high torque for lifting heavy loads — heavy-duty gear couplings handle the shock loads
of load pick-up and dynamic braking during controlled lowering cycles.

Gantry & Portal Cranes

Application Nu-Teck Coupling Nu-Teck Advantage
Gantry Crane Travel Drive (Rail-Mounted) Gear Couplings (Spacer Type) Drives large rail-mounted gantry cranes in steel plants and ports — spacer couplings absorb
rail joint shock and accommodate the significant shaft misalignment inherent
in long-span gantry structures.
Portal / Semi-Portal Crane Slewing Drive Gear Couplings Handles high inertia loads and continuous outdoor duty during slewing operations.

Jib, Pillar & Workstation Cranes

Application Nu-Teck Coupling Nu-Teck Advantage
Jib Crane Rotation & Hoist Drive Jaw Couplings Maintenance-free jaw couplings drive hoist and rotation mechanisms — snap-wrap elastomer replacement
allows quick servicing without disturbing the drive in congested workshop areas.
Workstation / Suspension Crane Drive Jaw Couplings Delivers clean, quiet operation for light-duty workstation cranes — jaw couplings dampen motor
vibration and allow easy maintenance without specialist tools.

Harbour, Ship & Heavy-Lift Cranes

Application Nu-Teck Coupling Nu-Teck Advantage
Ship-to-Shore (STS) Crane Hoist & Gantry Drive Gear Couplings (Heavy-Duty, Spacer Type) Handles extreme torque in high-cycle container handling — spacer type
allows rope drum or gearbox maintenance without disturbing the drive
motor in confined machinery spaces.
Harbour Mobile Crane Slewing & Luffing Drive Gear Couplings (Heavy-Duty) Drives slewing and luffing mechanisms, handling combined shock, reversal,
and high-torque loads of
marine lifting duty.
Floating Crane / Derrick Winch Drive Gear Couplings (Spacer Type) Transmits high torque to winch drums — spacer type absorbs angular misalignment
caused by hull flexure and accommodates winch drum removal.

Foundry, Steel Plant & Process Cranes

Application Nu-Teck Coupling Nu-Teck Advantage
Ladle / Casting Crane Hoist Drive Gear Couplings (Heavy-Duty, High-Temperature) Lifts and positions molten metal ladles in steel plants — engineered to operate under
extreme radiant heat in casting bays while supporting safety-critical loads.
Coil Handling & Strip Mill Cranes Gear Couplings & Jaw Couplings Handles steel coils and slabs with precision — gear couplings on hoist drives and jaw
couplings on auxiliary travel drives provide high torque capacity and low maintenance
in rolling mill environments.
Nu-Teck Customised Products for Crane Industries
Coupling / Product Type Description & Nu-Teck Advantage
Nu-Teck Heavy-Duty Gear Couplings Engineered for Hoist, Ladle Crane, and Harbour Crane main drives. Provides high shock
load resistance, high-cycle durability, and reliable performance in the
radiant heat environment of foundry and steel plant bays.
Nu-Teck Spacer Type Gear Couplings (Ext. DBSE) Extended spacer for EOT, Gantry, STS, and Winch drives accommodates bridge deflection
misalignment and allows wheel, drum, or gearbox maintenance without
disturbing the motor — minimising crane downtime.
Nu-Teck Jaw Couplings (Snap-Wrap) Maintenance-free operation for Cross-Travel, Jib, Workstation, and Auxiliary drives — snap-wrap
elastomer replacement in minutes without dismantling the drive line,
ideal for cranes in congested workshop areas.
