Double Girder Goliath Cranes
Double Girder Goliath Cranes Manufacturing
Double Girder Goliath Cranes are very versatile cranes used typically for activities in steel stockyards, pre-cast segment yards, and other outdoor applications. The double-girder Goliath crane offers an ideal solution for large-area transport of heavy loads. Portable and easy to relocate to any area or facility, they are operated with a master controller. Further advantages of these crane types are higher crane travel speeds, trolleys with walkways, service platforms, and auxiliary hoists. All the sections used for the main girders are computer-optimized in order to achieve high performance and low weight.
Key Features
- High-performance design: All main girder sections are computer-optimized for strength and low weight.
- Versatile operation: Higher travel speeds, service platforms, trolleys with walkways
- Customizable configurations: Available from 1 MT to 200 MT with tailored specifications for Safe Working Load
- Multiple hoisting options: Can be equipped with multiple trolleys or auxiliary hoists on the main trolley
- Precision control: Variable Frequency Drives ensure smooth and accurate motion in all axes.
Advantages
- Capable of carrying extremely heavy loads in industrial applications.
- Double girder design provides enhanced strength and stability for multiple simultaneous lifts.
- Enables movement in all three axes for flexible material handling.
- High-torque motors mounted on robust girders ensure reliable vertical lifting and safe operation.

Product Overview
Precision-Built for Modern Welding
The Horizontal Type Welding Turntable has been specially designed to meet modern welding requirements, incorporating features essential for efficient and economic welding production. Its primary function is to bring the weldment to a convenient position or to rotate the joint at a pre-selected speed so that a quality weld can be achieved along the circumference.
The drive system uses an AC Motor (Prime Mover) with three-stage speed reduction — a double-reduction worm gearbox plus a spur pinion and spur gear arrangement. An AC Variable Frequency Drive (VFD) provides stepless speed variation across the full range at constant torque. The faceplate is supported on grease-packed anti-friction bearings with sufficient preloading to eliminate axial movement during operation.
Key Advantages
- Increased production throughput with consistent weld quality
- Improved weld quality through controlled rotation speed
- Operable by less-skilled personnel, reducing training costs
- Reduced material handling time between welding passes
- Enhanced operator safety with stable workpiece positioning

Core Technology
AC VFD Control
Stepless speed variation throughout the full operating range at constant torque, enabling precise weld deposit control for any diameter workpiece.
3-Stage Gear Reduction
Double-reduction worm gearbox paired with spur pinion and spur gear stages delivers high torque, quiet operation, and long service life.
Anti-Friction Bearings
Grease-packed, preloaded anti-friction bearings support the faceplate, eliminating axial movement and ensuring a stable, vibration-free weld environment.
Knowledge Base
What is a Horizontal Welding Turntable?
A horizontal welding turntable is a motorized workholding device that rotates a weldment in the horizontal plane at a precisely controlled speed. Also referred to as a horizontal type welding turntable, faceplate turntable, or welding rotary table, it allows the welder or welding torch to remain stationary while the workpiece is continuously presented at the optimal joint position.
This design enables circumferential and fillet welds to be deposited consistently in the flat (downhand) welding position — the most favourable position for weld quality, deposition rate, and operator ergonomics. The result is a significant improvement in bead uniformity, reduced weld spatter, and faster production throughput compared to manual repositioning.
Cu-Built’s horizontal welding turntables are engineered with a three-stage gear reduction system and an AC Variable Frequency Drive (VFD) for stepless speed variation, making them ideal for MIG, TIG, SAW (Submerged Arc Welding), and plasma welding processes across a wide range of workpiece diameters and weights.
