Description
The polyurethane bumper or buffer is a safty device for
anti-collision of crane and hoist trolley frame. When the position
limiter or brake of the mechanical bridge crane is malfunctioning,
the overhead crane or trolley running to the end due to inertia
will collide with the provided stop at the running end. The purpose
of setting the buffer is to absorb the crane or crane operation
function to slow down the impact. The buffer is set at a position
where the crane or trolley is in collision with the stop. A buffer
should also be provided between the cranes running on the same
track and between the two carriages on the same bridge.
FEATURES
1. Application: Polyurethane rubber buffer for anti-collision of
crane and trolley
2. Polyurethane buffer with good hardness, good strength, quick
recovery, oil resistance, aging resistance, acid and corrosion
resistance.
3. Light dead weight, simple mechanism, low price and noise, no
spark, easy installation and maintenance, long service life.
4. Based on its way of connection, polyurethane buffer could be
divided into three series: stud type (JHQ-A), platen type (JHQ-B)
and flange-plate type (JHQ-C). For each series, there are *4 to *1
specifications, and each specification corresponds to the
buffer of each capacity.
