Product description
The four girder casting crane adopts a four-beam, four-track and double-trolley structure type. The main structure has excellent strength and rigidity under vertical and horizontal loads. The large vehicle wheels adopt a 20-wheel arrangement, with a simple mechanical model and balanced wheel pressure distribution, which can effectively reduce the cost of the factory building's steel structure.
The foundry crane is designed to be operated efficiently, uninterruptedly and safely in continuous use.The design conforms to the requirements of international standards.
Because of a higher risk level, special safety features are designed for the foundry crane that transport molten metal. The main hoist mechanism includes four independent rope reevings, double service brakes on primary shafts, and backup brake acting on the rope drum. Rope equalizer beams are provided with a dampening unit to slow down equalizer beam tilting in case of wire rope failure. An upper emergency stop limit switch is also used in the main hoist. In addition to this overload protection, the ‘emergency stop’ system bypassed from PLC, derailment supports, main hoist over speed supervision, and end limit switches are automatically standard features of the equipment.

Case
Application
The foundry crane utilized for medium to heavy fabrication. These overhead cranes are ideally suited to casting factory.The Foundry crane is the main equipment for steel smelting production.
It is used to move steel or iron ladles in steel smelting workshop with high temperature and a lot of dust.
