Falling Impact Test Machine

I. Application range:
JL series falling type impact testing machine applies to ferrite steel of various kinds, especially drop-weighted tear test (DWTT) for pipeline steel of various kinds. Whats more, other types of impact tests can be carried through on hammerhead and anvil bed of various kinds according to clients requirements.

II. Service performance:
1. JL series falling type impact testing machine can adjust impact energy by way of regulating hoisting height or fluctuating number of balance-weighted.
2. Equipped with buffer, this machine is capable of absorbing dump energy after sample efficiently to protect hammerhead and anvil bed from damaging. In addition, this machine is equipped with guard net, safety pin for maintenance use, hook locking testing as well as other safeguard protection mechani***s.
3. Equipped with automatic-sample mechani***, sample-backward preventing mechani*** and centering mechani***, this machine assures rapidity, accuracy and reliability of test.
