1. High safety and reliability:
Buffer device: High-strength polyurethane buffers or hydraulic
buffers are installed at both ends of the end beam to effectively
absorb collision energy and protect the end beam and track.
Travel limit switch: A trigger-type or inductive travel limit
switch is installed on the end beam (sometimes a collision ruler or
induction plate is installed on the outside of the end beam) to
ensure that the crane automatically decelerates and stops before
the extreme position at both ends of the track.
Anti-derailment device: The design fully considers the
anti-derailment capability, such as sufficient wheel flange height,
reasonable wheel-rail gap, guide wheel design, etc. Some designs
will also be equipped with additional anti-derailment measures such
as safety hooks.
Braking safety: The built-in brake of the three-in-one drive unit
has reliable performance, usually a disc brake or a conical rotor
brake, with large braking torque and fast response to ensure safe
parking.
2. Modular and standardized design:
The connection interface between the end beam and the main beam is
standardized, which is convenient for combination with main beams
of different spans.
Key components such as drive units, wheel sets, buffers, etc. also
tend to be standardized and modular, which is convenient for
production, installation and commissioning, spare parts replacement
and maintenance.
3. Good protection and lubrication:
The key transmission parts such as bearings and gears have good
sealing protection, and the protection level usually reaches IP54
or higher, which is suitable for the factory environment.
Reasonable lubrication design, such as centralized automatic
lubrication or long-lasting grease, reduces the maintenance
frequency.
4. Low running resistance and energy consumption:
The optimized structural design, efficient transmission
(three-in-one drive, low-friction bearings), and reasonable
wheel-rail contact (such as horizontal guide wheels) work together
to significantly reduce the running resistance, thereby reducing
the power demand of the drive motor and achieving energy-saving
operation.
In summary, the core features of the 32-ton European double-beam
end beam are:
Compactness, lightness and convenient maintenance brought by high
integration (three-in-one drive).
High-strength and high-wear-resistant wheels and bearings ensure
reliability and long life under heavy loads.
The horizontal guide wheel or double wheel flange design ensures
extremely smooth operation, precise guidance, low noise and low
wear.
Complete safety protection devices (buffer, limit, anti-derailment)
ensure safe operation.
Standardized and modular design improves production efficiency and
maintainability.
The overall design pursues high efficiency and energy saving.
