Heavy-Duty End Carriage Beam 1 Ton Gear Motor Drive For Overhead Gantry Cranes

 

 

The crane end carriage is a core traveling component of overhead cranes, gantry cranes and overhead cranes, installed at both ends of the main girder to support the entire crane structure and drive horizontal movement along the runway. Constructed with high-strength welded box-section steel, it integrates precision wheels, drive motors, gearboxes, safety buffers and anti-derailment devices. Featuring modular design, high torsional rigidity and stable operation, it ensures synchronized, smooth and safe travel under heavy loads, adapting to various industrial lifting scenarios with high reliability and durability.

 

Designed specifically for heavy-duty crane operation scenarios, our crane end carriage takes rigidity, stability, safety and durability as the core orientation. Different from ordinary end carriages, it optimizes structural design and component selection to effectively avoid common problems such as structural deformation, loud operation noise and easy derailment. While ensuring strong load-bearing capacity and smooth travel, it also simplifies maintenance procedures, bringing more reliable and convenient use experience to users. The core functional advantages are as follows.

High-Rigidity Box Structure: Made of Q235/Q355 high-strength steel plate, fully welded and annealed, with excellent torsional resistance, deformation resistance and load-bearing capacity.

Precision Wheel Assembly: Forged steel/ductile iron wheels, heat-treated to high hardness, matched with heavy-duty bearings, ensuring low noise, low friction and long service life.

Integrated Drive System: Equipped with high-efficiency parallel shaft/helical gear motors, soft start/stop design, stable torque, reducing load swing and equipment wear.

All-Round Safety Protection: Standard rubber/hydraulic buffers, anti-derailment guards, limit switches and lift-off protection, preventing collisions and track derailment.

Modular & Customizable: Bolted connection for easy installation with main girder; customizable span, wheel diameter, load capacity and driving mode (single/double motor).

Corrosion-Resistant Finish: Surface shot blasting + two-layer paint coating (or galvanizing), excellent rust and corrosion resistance for harsh environments.

Structure & Components

The overall structure of the crane end carriage adopts a scientific and reasonable modular design, which is different from the traditional integrated structure. Each core component is selected through strict quality inspection and processed with precision craftsmanship to ensure that the overall performance is stable and reliable. The reasonable layout of each component not only enhances the load-bearing capacity and travel stability of the end carriage but also makes installation, daily maintenance and vulnerable parts replacement more convenient and efficient.

Main Frame: Welded box-section steel with internal diaphragms, high rigidity, stable structure.

Wheel Block: Precision-machined wheels, tapered roller bearings, dust-proof seal.

Drive Unit: Gear motor (integrated with reducer), coupling, transmission shaft.

Safety Parts: Rubber/hydraulic buffers, anti-derailment guards, limit switches.

Connection Plate: Machined mounting surface, bolted connection with main girder.

Accessories: Track sweeps, lift-off protection, cable clips.

 

Safety Features

Different from ordinary products that only have basic safety protection, our end carriage integrates a multi-layer, all-round safety protection system, which comprehensively covers all potential safety risks during operation, such as collision, derailment, motor burnout and overtravel. Each safety device is tested and calibrated one by one before leaving the factory to ensure that it can play a stable protective role in various harsh working conditions and fully protect the safety of equipment and personnel.

Dual Safety Buffers: Absorb impact energy during collision, protecting crane and runway.

Anti-Derailment System: Guards and wheel flanges prevent deviation from track.

Travel Limit Switch: Automatically stops at track ends to avoid overtravel.

Overload Protection: Motor with thermal overload protection, preventing burnout.

Synchronized Travel: Dual-drive design ensures left-right synchronization, no deviation.

 

Installation & Maintenance

In order to facilitate user operation and reduce later use costs, our crane end carriage adopts a simplified modular installation design, which does not require complex professional equipment and technical personnel, and ordinary operators can complete the installation according to the guidelines.
