Karl Georg OLYMP interchangeable wheel block systems

OLYMP wheel blocks are engineered for swift one-to-one exchange of crane wheel assemblies without altering structural connection points. An internal gear connection and heavy-duty bearing configuration provide extended service longevity across demanding travel cycles.

Wide travel wheel spectrum from 125 to 500 mm tailored to rail geometries
Direct one-to-one mechanical interchangeability without modifying crane frames
Internal splined wheel hub interface for straightforward geared drive coupling
Reinforced load capacity provided by sealed heavy-duty roller bearing units

Karl Georg CERTUS industrial hydraulic buffers

CERTUS industrial hydraulic buffers provide controlled dissipation of kinetic energy on bridge cranes and heavy trolleys. A closed twin-chamber arrangement manages damping forces up to 520 kN with stroke lengths between 100 and 800 mm under demanding deceleration cycles.

Cylinder bore diameters of 75, 95, and 115 mm with stroke lengths reaching 800 mm
Peak calculated deceleration buffer force absorption rated up to 520 kN
Rigid flange mounting configurations featuring front or rear plate interfaces
Hard chrome plated piston rod finish combined with heavy-duty seal packages

Karl Georg TITAN KG 130 heavy-duty wheel sets

TITAN KG 130 wheel sets are engineered for crane travel drives and heavy transfer carts, supporting wheel loads up to 60 metric tons. Assemblies integrate forged axles, wheels from 160 to 630 mm, and corner bearing housings for seamless insertion into box girder beams.

Wheel tread diameter spectrum from 160 to 630 mm with tread widths up to 160 mm
Maximum permissible static and dynamic travel load rated up to 60000 kg per wheel
RAE and RNE assembly variants built for corner bearing housings or girder pockets
Precision machined axle journals ensuring balanced torque from geared drives

Karl Georg rope sheaves under DIN industrial standards

Karl Georg rope sheaves are built according to DIN 15417, 15418, 15421, and 15422 for hoisting winches, reeving blocks, and bridge trolleys. Grooves receive high-frequency induction hardening to reduce wire rope contact abrasion and extend equipment inspection intervals.

Standardized profiles conforming to German norms DIN 15417, 15418, 15421, and 15422
Precision machined groove radius matching specific wire rope diameter requirements
Induction hardening applied to rope track surfaces preventing mechanical grooving
Equipped with heavy-duty radial bearings and labyrinth seals against dust ingress

Engineering standards and tolerances of Karl Georg wheels

Karl Georg crane travelling wheels are manufactured in accordance with DIN 15074, 15075, 15078, 15079, 15093 specifications and KG factory norms 010.1 to 030.

Precision machining on modern turning and grinding centers maintains radial and axial runout within tight boundaries defined by ISO industrial norms.

Induction hardening applied to tread surfaces and wheel flanges achieves uniform hardness of 45 to 55 HRC down to depths of 8 to 12 mm, which prevents contact deformation and uneven rail track degradation.

Raw billets forged from C45 carbon steel or alloy steel undergo ultrasonic evaluation to verify total absence of internal structural flaws or inclusions.

Mounting and integration of ATLAS modular wheel blocks

ATLAS modular wheel blocks are designed for accelerated mounting within end carriage beams of overhead cranes and transfer trolleys. The structural housing is produced from ductile spheroidal graphite iron featuring milled connection planes for multi-directional bolt fastening.

Adjustable setting components allow precision alignment of the wheel axle relative to the crane track center line, avoiding skewing forces and flange rubbing.

When servicing discontinued RB 250 wheel block installations, maintenance teams can select the direct successor model RB 250-V or procure standardized running assembly components to preserve original operational performance.

Direct one-to-one interchangeability of OLYMP wheel blocks

Karl Georg OLYMP wheel blocks provide a complete one-to-one mechanical alternative for common crane wheel assemblies across European heavy industries.

Connection dimensions, hole arrangements, and drive interface positions correspond with existing crane frameworks, allowing travel drive modernizations without structural frame modifications.

The internal splined wheel hub transmits drive torque from direct-coupled geared motors smoothly without play, while dual-row heavy roller bearings with labyrinth sealing rings isolate the axle interior from industrial debris, moisture, and particulate matter encountered during demanding duty cycles.

Calculation and selection of CERTUS hydraulic buffers

CERTUS safety hydraulic buffers dissipate kinetic energy generated by crane movements and heavy transfer cars upon approach to end stops.

The closed twin-chamber hydraulic arrangement controls fluid displacement through calibrated apertures, ensuring smooth deceleration profiles that protect structural workshop columns and trolley chassis from severe peak shock loads.

The buffer piston rod features corrosion-resistant hard chrome plating and resilient wiping seals, guaranteeing dependable damping performance across fluctuating operating temperatures between minus 30 and plus 80 degrees Celsius.

TITAN heavy-duty wheel sets for demanding crane trolleys

TITAN KG 130 heavy-duty wheel sets support static and dynamic travel loads up to 60 metric tons per wheel in metal processing plants and port terminal applications.

Each complete wheel set includes a heat-treated alloy steel axle, wheels from 160 to 630 mm in diameter, and robust RAE or RNE corner bearing housings for direct mounting into box girder carriages.

Axle bearing journals are precision ground to accept cylindrical or spherical roller bearings, maintaining running concentricity and uniform contact pressure distribution across the rail profile under maximum load.

Maintenance routines and alignment of DIN rope sheaves

Rope sheaves built to DIN 15417, 15418, 15421, and 15422 standards require periodic inspection of groove radius profiles and radial bearing clearances.

The machined groove radius is matched to the specific wire rope diameter, preventing cross-sectional pinching and wire fatigue under repetitive tensile stress. High-frequency induction hardening of the wire groove minimizes surface wear and prolongs rope lifespan across complex reeving systems.

Technical specialists assist engineering departments in reviewing dimensional sketches and specifications for swift component selection.
