Double Girder Casting Crane
The casting crane (hereinafter the crane) is dedicated lifting equipment for metal smelting environments. It transfers, pours and charges molten metal intermittently and repeatedly during smelting, with vertical lifting plus longitudinal and transverse travel. The load-handling device is a gantry-type spreader; duty class A7.
Type test specification: YZ
Type test product name: Metallurgical Overhead Crane
Advantages & features
- 01
The control console has a PLC module and HMI touchscreen with a WLK master controller: distinct feel, clear positions, zero-position self-return and locking. Hoisting uses stator voltage regulation and travel uses variable-frequency control for smooth starting and braking and accurate positioning of the load.
- 02
Key structural parts such as the main and end girders have heat insulation protection and withstand radiant heat, ensuring stable long-term operation in high-temperature shops. The 45° split wheel retaining blocks are machined in one set-up on a large boring machine, preventing wheel flange wear against the rail, ensuring mounting accuracy and extending overall crane service life.
- 03
The crane is fitted with a safety monitoring system and uses PLC plus inverter communication control throughout; load-bearing members are designed through precise finite element analysis, so the equipment runs more smoothly. The hoisting mechanism has dual protection against the hook over-travelling.
