1. Precise control and smooth operation:
Frequency control (especially for lifting and trolley operation) is
often used to achieve stepless speed change, smooth start/stop, and
precise positioning, which greatly reduces the impact load on the
crane and the plant, protects the cargo, and improves the comfort
and efficiency of operation.
Optional PLC control system to achieve more complex logic control,
status monitoring and fault diagnosis.
2. Perfect safety protection device:
Overload limiter: The core safety device monitors the load in real
time, automatically cuts off the dangerous direction action and
alarms when overloaded.
Height limiter: Prevents the hook from hitting the top (up limit)
and excessive lowering (optional lowering depth limit).
Travel limiter: Automatically slows down and stops when the trolley
and the trolley run to both ends of the track to prevent collision.
Anti-collision device: When multiple cranes are running in the same
span, install anti-collision devices such as
laser/ultrasonic/infrared to avoid collision.
Emergency power off switch: Set in a conspicuous position in the
driver's cab and the crane.
Sound and light alarm: Gives a warning before operation or in case
of failure.
Electrical protection: short circuit, overcurrent, phase loss,
pressure loss and other protection.
End stop and buffer: physical limit and collision energy
absorption.
3. Flexible control mode:
Cab operation: Provide the best view and operating environment,
especially suitable for large span, high altitude or complex
working conditions. The cab usually moves with the trolley.
Ground operation: Operate on the ground through the remote control
or follow-up button box, the operator's field of view is closer to
the goods, flexible and convenient, saving labor costs (no need for
the driver to climb). Frequency conversion control makes ground
operation positioning equally accurate.
Two modes can be switched: Many cranes are designed to switch
between cab and ground operation.
4. Higher installation requirements:
The dead weight is very large (usually tens of tons or even
hundreds of tons), and the load-bearing structure (columns,
columns) and track foundation of the plant are extremely high.
Track installation must be accurate (gauge, horizontality,
straightness).
The installation process is complicated and usually requires a
professional team.
Relatively high initial investment and maintenance costs:
Compared with small tonnage or single-beam cranes, the purchase
cost of a 50-ton double-beam bridge crane is significantly higher.
Its complex structure and core components (motor, reducer, brake,
wire rope, wheel, etc.) also mean that the maintenance cost is
relatively high, requiring a professional maintenance team and
planned maintenance.
5. Wide range of applications:
Mainly used in heavy industrial environments: metallurgical plants
(ladles, ingots, continuous casting billets), heavy machinery
manufacturing plants (large parts assembly), foundries (sand boxes,
castings), power stations (generator stators, rotors,
transformers), port terminal rear yards, large warehouses, railway
freight yards, major equipment installations, etc.
