1. General-purpose Overhead Travelling Crane
Characteristics
Wide range of uses:
It can be used in various operations such as material lifting and equipment installation in workshops, warehouses, factory buildings and other places under general environments.
Typical structure:
Composed of the bridge frame (track for the trolley to run), the trolley equipped with lifting and running mechanisms, the trolley running mechanism, the control room and other components.
Lifting mechanism:
Usually equipped with conventional lifting tools such as hooks for vertical lifting of heavy objects.
Running mode:
The trolley runs horizontally along the track on the bridge frame, and the trolley runs longitudinally along the track laid on the ground.
2. Simple Beam Overhead Travelling Crane (Beam Crane) Characteristics
Relatively simple structure:
The main beam of the bridge frame is a simple cross-section beam composed of I-beams or other section steels and plate steels.
Small lifting capacity and span:
Suitable for small operation sites or lifting of lightweight materials. Simple lifting trolley:
Usually a hand-pulled hoist or an electric hoist with a simple trolley. Running mode:
The trolley generally runs on the lower flange of the I-beam. The bridge frame can run along the track on the elevated structure or along the track suspended under the elevated structure (in this case, it is a suspended beam crane).
3. Special Overhead Travelling Crane for Metallurgy
Characteristics
Special operation environment: Specifically used in specific process of metallurgical industries such as steel production.
Various types:
Casting crane:
Used for lifting molten iron into the mixer, steel-making furnace and lifting molten steel into continuous casting equipment or ingot molds, etc. It is often equipped with main and auxiliary trolleys, and the auxiliary trolley assists the main trolley to complete the operation. Clamp crane:
Used for vertically lifting high-temperature ingots to specific positions (such as soaking furnaces).
Ingot stripping crane:
Used for forcibly stripping the ingots from the ingot molds.
Charging crane:
Used for adding furnace charges to the open-hearth furnace, with special structures such as movable poles.
Forging crane:
Cooperates with the hydraulic press to forge large workpieces, and the hook has a special turning device, etc.
High working level:
Due to frequent use and harsh working conditions.
4. Grab Overhead Travelling Crane
Characteristics
Main lifting tool:
Equipped with grabs and used for loading, unloading and lifting operations of bulk goods, waste steel, wood, etc.
Grabbing function:
Grabs and discharges materials by opening and closing the grabs. Structural basis:
Except for the lifting and closing mechanism (matching with the grabs), other structural components are the same as those of the general hook overhead travelling crane.
5. Electromagnetic Overhead Travelling Crane
Characteristics
Special lifting device:
Equipped with electromagnetic chucks.
Applicable materials:
Used for handling ferromagnetic black metals and their products, etc. Operation mode:
Lifts and transfers materials by the magnetic force of the electromagnetic chucks.
6. Three-purpose Overhead Travelling Crane
Characteristics
Versatility:
The basic structure is the same as that of the electromagnetic overhead travelling crane.
Multiple operation modes:
Can lift heavy objects with hooks; can hang a motor grab on the hook to load and unload materials; can also remove the grab and then hang the electromagnetic chuck to lift black metals.
7. Explosion-proof Overhead Travelling Crane
Characteristics
Application environment:
Mainly applied in environments with explosive gases.
Safety:
Strict explosion-proof measures are taken in the motor and electrical parts and mechanical parts such as metal contact surfaces to ensure the safety of operation in an explosion-proof environment. Classification:
There are explosion-proof overhead travelling cranes for coal mines and explosion-proof overhead travelling cranes for factories (with explosion-proof certificates issued by the national testing center).
8. Double-trolley Overhead Travelling Crane
Characteristics
Structural feature: Two trolleys with the same lifting capacity are installed on the bridge frame.
Lifting objects:
Used for lifting and loading/unloading long-shaped objects and other special working conditions.
Cooperative operation:
The double trolleys can cooperate as needed to complete complex lifting tasks.
