1. Integration of safety protection devices:
Buffers (car stops): Buffers of sufficient capacity (polyurethane
or hydraulic) must be installed at both ends of the end beam to
absorb the impact energy when the crane runs to the end of the
track.
Trolley travel limit switch: Trigger the impact ruler or induction
device to automatically cut off the trolley running power when
approaching the end of the track.
Anti-collision device (optional): When there are multiple cranes in
the same span or there are obstacles, anti-collision devices such
as lasers and ultrasonic waves may be installed.
Track sweeper: Clear obstacles on the track.
Guardrails on both sides of the end beam: Ensure the safety of
maintenance personnel.
2. Double-sided drive:
50-ton cranes usually use double-sided drive, that is,
"three-in-one" drive mechanisms are installed on both end beams.
This provides sufficient driving force and braking torque to ensure
smooth start-up, operation and braking of large-tonnage cranes, and
effectively prevents the "track gnawing" phenomenon that may be
caused by unilateral drive.
3. Precision processing and installation interface:
The processing accuracy of the flange surface connecting the end
beam and the main beam is high to ensure the horizontality and span
accuracy of the main beam after the main beam and the end beam are
connected.
The parallelism, verticality and horizontal deflection between the
wheel treads are strictly required to ensure smooth operation and
reduce wear and rail gnawing.
4. Easy installation and maintenance:
The modular design (especially the three-in-one drive) makes
on-site installation, commissioning and subsequent maintenance
(such as replacement of wheels, drive units, bearings, etc.) more
convenient and quick.
Summarize the core features of the 50-ton European double-beam end
beam:
Lightweight and high strength: core advantages, reducing plant load
and cost.
Compact integration: "Three-in-one" drive is the hallmark, compact
structure, and space saving.
High load and stability: multi-wheel arrangement (4 or 8 wheels),
solid box beam, meet 50tons of load and dynamic requirements.
Bilateral drive: ensure driving force, braking force and smooth
operation under large tonnage.
Smooth and reliable operation: Optimized wheel design, precision
machining and high-quality bearings.
High safety: Integrated buffer, limiter and other safety devices.
Easy maintenance: Modular design, especially the three-in-one drive
unit is easy to replace.
