1. Heavy-duty angled bearing housing and precision adjustment:
The wheel set uses a heavy-duty, enlarged angled (or square)
bearing housing to accommodate larger spherical roller bearings.
Equipped with a more precise horizontal deflection adjustment shim
set and vertical adjustment device to ensure that the parallelism,
verticality and horizontal deflection of all wheels (especially in
multi-wheel trolley systems) are controlled within an extremely
strict range, which is the key to ensuring smooth operation, low
wear and no rail gnawing.
2. Enhanced safety protection device:
Larger capacity buffer: Heavy-duty hydraulic buffers or ultra-large
capacity polyurethane buffers are installed at both ends of the end
beam to absorb the huge kinetic energy when the 63-ton crane runs
at high speed to the end of the track.
Redundant travel limit: Usually equipped with two-level (working
limit + emergency limit) or even three-level trolley travel limit
switches.
Enhanced anti-collision system: More likely to be equipped with an
active anti-collision system based on laser, radar or encoder for
detection and deceleration/stop control of multiple cranes or fixed
obstacles in the same span.
Stronger track sweeping plates and guardrails.
3. Ultra-high precision manufacturing and installation:
The overall processing of the end beam (especially the flange
surface connected to the main beam) requires higher precision to
ensure the horizontality and span accuracy of the main beam after
installation.
The centering of the wheel group of the multi-wheeled balancing
trolley and the horizontal adjustment of the trolley frame are the
key difficulties in installation and commissioning, which require
professional tools and rich experience to ensure that all wheels
are evenly loaded and run synchronously.
4. Modularity and maintainability:
Although the structure is more complex (especially with a balancing
trolley), the design still strives for modularity: the drive unit,
a single balancing trolley, the wheel group, etc. can be replaced
as a module as a whole to reduce downtime.
Provide sufficient maintenance channels and hanging points.
