During
Crane or trolley running, the brakes or limit switches may suddenly break down.
Due to inertia, the vehicle will continue in the state of motion until running
into the end stop preset at both ends of its runway track. The aim of adding a
crane buffer to the contact area between the end stop and trolley or crane is
to absorb the majority of energy produced in an impact shock. Following is a
list of two buffer forms most commonly in use today.
Polyurethane Buffer
Advantages
Lightweight
design available at a competitive price
Ease
of maintenance and repair
Resistant
to corrosion, impact and stress
Generate
neither noise nor sparks during operation, thus suitable for use in explosive
atmosphere.
Technical
Features
Crane
buffer density:0.55-0.65
Shore
hardness:50-65
Compressive
Strength(50% compression):12-15kg/cm2
Operating
Temperature:-30-60 degrees
Hydraulic
Buffer
Advantages
With
the increase in the extent of compression, the number of holes that allow fluid
to pass through will be reduced to ensure a uniform speed at which the
buffering process is carried out.
Despite
its compact design, this series of crane buffer is able to absorb a large
amount of energy.
This
hydraulic buffer enables a maximum deceleration of the running crane or trolley
while coming in a minimum size. For cranes with high mass or speed exceeding
2m/s, the buffer just provides a most suitable solution.
Technical
Features
Absorb
80% to 100% of energy produced in impact shock
Angle
of deflection after collision is controlled within the range between 0 and 1
Operating
temperature:-25~80 degrees

Â
The meters can be equipped with a kind of remote transmission device, the pulse generating volume could be 10,1000 or 10000 L/pulse.
 
Working condition:
Water temperature: 0.1ºC~50ºC (0.1ºC~90ºC for hot water meter)
Water pressure: ≤1.0Mpa (1.6MPa on request)
Maximum permissible errors:
in the lower zone from qmin inclusive up to but excluding qt is ±5%
in the upper zone from qt inclusive up to and including qs is ±2% (±3% for hot water meter)
