LDY Metallurgical Single Girder Overhead Traveling Cranes
Metallurgical Single Girder Overhead Cranes Information
LDY Metallurgical Single Girder Overhead Cranes is used for lifting of melting metal sites of metallurgy, casting, its matching lifting mechanism is YHⅡ metallurgy electric hoist, the weight is less than 10 t. The bottom of main beam using special insulated heat . Working ambient temperature is 40℃- 60℃, humidity no more than 50%. Crane design and manufacture meet the State administration of quality supervision, inspection and quarantine of the quality of writing "2007" document No. 375, lifting other molten metal items and lifting hot solid metal location can also refer to the selection.
Metallurgical Single Girder Overhead Cranes Security measures
1) Double limit: Two sets of effective double power-off limiters are set
2) Overhead limiter:
When the hoisted object reaches 90% of the rated load, the limiter will alarm: when it reaches 95%, it will continue to alarm: when it reaches 105%, it will automatically power off and stop working
3) Insulation protection:
Install a double-layer heat insulation (internal heat insulation material) protective layer device on the lower part of the host and hooks.
4) Steel wire rope: The configuration model is 18×7+1WS high temperature resistant steel core steel wire rope.
5) Cable line:
To prevent the occurrence of dangers such as disconnection and loss of control caused by wire aging, adhesion, etc., which are prone to frequent exposure to high temperature environments, install high temperature resistant cables.
6) Distribution box:
To avoid damage to electrical components caused by high temperature and easy failure, the distribution box should be installed far away from direct heat sources and installed at the end of the taxi.
7) Reducer:
The reducer adopts helical gear three-stage reduction, and the gear and shaft are made of alloy steel or high-quality carbon steel.
8) Reel device
The reel is made of cast steel or seamless steel pipe. The spline is used to transmit power, and the drum shell is welded with steel plate
9) Hook device
The hook is made of steel forging, and the thrust ball bearing is used to connect with the shell through the hook beam, so that the hook can run freely.
