Overview Of Hydraulic Rail Bending Machine
Hydraulic Rail Bending Machine, aka rail bender,
is a special tool for rail bending during railway track installation and maintenance.
Overview////////////////////////////////
Hydraulic Rail Bending Machine is a commonly used instrument for laying and maintaining railroads.
Hydraulic Rail Bender can bend straight rails on demand and can straighten rails.
According to the principle of work, rail bending machine can be divided into mechanical and hydraulic type.
Advantage of mechanical rail bender is to straighten, bend or bend railway track to sharp-angled at one time.
Advantages////////////////////////////////
Advantage of Hydraulic Rail Bending Machine is labor-saving,
can complete bending or straightening track movements by one person,
unloading fast, can quickly get a lot of rails bend. Drawback is that vulnerable cylinder part needs high maintenance costs;
Hydraulic rail bender can only bend small curve rails, several times to complete with curve less than 150 °.
Suitable for round and arc curved rails.
Working Principle Of Hydraulic Rail Bending Machine
Hydraulic Rail Bending Machine is designed on hydraulic transmission and leverage principle, which uses the static pressure for horizontal, horizontal curve bending or straightening operations.

Classification Of Hydraulic Rail Bending Machine
Hydraulic Horizontal Rail Bending Machine has two styles of single hook and double rail.
KWPY-300 Hydraulic Horizontal Rail Bending Machine -- horizontal bending for rails below 24kg / m with a minimum bend radius of 7M.
KWPY-400 Hydraulic Rail Bending Machine -- horizontal bending for 30kg / m rails.
KWPY-600 Hydraulic Rail Bender -- for horizontal bending of rails from 30kg/m to 50kg/m
KWPY-III hydraulic Rail Straighten Machine (Rail Bender) -- for horizontal bending operation with rails below 24kg/m h, the minimum bending radius of 5m
