reliability, and an ergonomic structure. With proven performance,
the instrument has been exported to key markets such as Europe and
North America, gaining wide recognition from global customers.
Meet standards:
It meets the technical conditions of industry standard JB / T9389
drop hammer impact test machine, and meets the test methods of GB /
T14152, GB / T10002.1, GB / T5836.1, GB / T13664, GB / T16800,
ISO4422, ISO3127, BSEN1411 and BSEN744.
Instrument characteristics:
1. Three-Level Safety Protection System
The tester is equipped with a multi-layer safety protection
mechanism to ensure operational safety:
- 1st level: Sample door interlock protection;
- 2nd level: Observation window interlock protection;
- 3rd level: Upper and lower limit position protection.
2. High-Speed Lifting Performance
Powered by a high-torque stepping motor, the tester achieves a
lifting speed of up to 250 mm/s—enabling the hammer to reach a
height of 2 meters from 0 in just 8 seconds. This significantly
shortens the test cycle and improves operational efficiency.
3. Intelligent Hover Function
Adopting a multi-stage speed control program, the tester ensures
smooth hammer stopping and precise positioning with zero deviation.
This advanced control logic eliminates inertial displacement,
guaranteeing consistent test conditions.
4. 3D-Modeled Drop Hammer Guide Pipe
The drop hammer guide pipe is optimized via 3D modeling, integrated
with exhaust holes to minimize wind resistance during hammer
drop—ensuring stable and repeatable impact force. Additionally, a
hoop reinforcement structure is added to the pipe to prevent
structural failure and deformation, enhancing long-term operational
reliability.
5. Pneumatic Hammer Lifting & Releasing Mechanism
Abandoning traditional electromagnetic hammer mechanisms, the
tester adopts a high-force pneumatic structure:
- Equipped with 300N long-stroke dual air cylinders for powerful and
stable operation;
- Features a rubber tendon plate hammer surface to ensure
non-damaging impact and consistent contact with samples;
- The pneumatic hammer releasing/lifting design fundamentally
eliminates issues such as cable bending, wire breakage, and
electrical leakage common in electromagnetic systems;
- Incorporates a pneumatic automatic locking structure for enhanced
safety and reliability.
6. Integrated & Modular Assembly Design
- Mechanical structure: Adopts standard aluminum alloy profile
assembly, achieving process standardization, modular installation,
and a lightweight yet high-strength design;
- Electrical system: Configured with a 7-inch touchscreen and Delta
PLC, ensuring intuitive operation, stable performance, and easy
maintenance.
7. Premium Component Quality & Comprehensive Safety Precautions
All core components are sourced from renowned brands:
- Air cylinders: Adker;
- Touchscreen & PLC: Delta;
- Power supply: Taiwan Mean Well.
Comprehensive safety protections are integrated across electrical,
mechanical, and software systems, including: leakage protection,
short-circuit protection, anti-static protection, anti-interference
protection, pressure leakage protection, power failure protection,
and misoperation protection—fully complying with international
safety standards.
8. High Degree of Automation
The tester supports full-automatic test processes, including
automatic zero-point calibration, automatic hammer lifting,
automatic hammer releasing, and automatic test execution. This
minimizes manual intervention, reduces human error, and improves
test efficiency and data consistency.
