Combined mechanical and hydraulic technology
The rail-bound manipulator employs a hydraulic and mechanical combination technology.
A mechanical-hydraulic hybrid machine that runs on rails, used to transport hot and cold ingots, discs and rings in open die forging plants — with travel, rotation, clamping and lifting via tong, vice or fork.

Overview
The forging charger is a mechanical-hydraulic mixed type machine used to transport cold and hot ingots, discs and rings in open-die forging plants, ring mills, blooming mills and similar facilities.
Work types include clamp-support, clamp-hold and fork configurations, enabling manipulator movement, upper rotational capability, clamp rod flexing and lifting operations.
Key data
Full technical parameters are confirmed together with our engineers, based on your part and production volume.
Features
The rail-bound manipulator employs a hydraulic and mechanical combination technology.
Operating modes include clamping, holding and fork-type tongs.
Functional movements encompass travelling, upper-section rotation, clamp rod extension and retraction, vertical clamp movement and head rotation.
Efficient forging processes with high performance capability and reduced operational costs.
Rapid movements with the highest precision are achieved.
Forging quality and production line capacity are significantly increased.

Advantages
Every motion — travel, rotation, clamping, lifting — is hydraulically driven, delivering constant force and fine speed control.
01Manual, semi-automatic or fully automatic operation, with the option to digitally synchronize with the forging press or hammer.
02Reduces downtime and operator physical effort, significantly raising the output rate of the forging line.
03From high-capacity CNC manipulators to mobile and rail-mounted models, adapted to any workshop layout.
