5. Tup body is made of high strength steel plate with high impact resistance

6. Use chain to lift tup with high precision in height

7. Self-lock design for tup clamping

8. Full-closed safety shield

Main frame
Main frame is constructed with bottom plate, four columns, and top plate. Bottom plate is made of 45# steel plate; Four columns are steel pipes for four-point support to ensure the stability, top plate is made of LY12 aluminium plate. Connections between columns and bottom and top plate are used with flange. Though the whole frame is high, the center of gravity is low with better stability. The top plate is made of light aluminium with easy installation. Guide rail is constructed with precise smooth bar, with surface chrome plated and hardened, with good linearity and high precision. Two ends of smooth bar are tightened by screw and bolts, ensuring high rigidity of main frame and rail, avoiding any loosen components caused by vibration.

Striker
Striker is made of whole machined steel plate, ensuring the striker stiffness and improving the safety, not loosening after long time use. Striker tup is made of alloy steel, with good impact resistance, little abrasion, long service life, and easy to change.

Lifting system
Lifting system consists of motor, crosshead, chain wheel, chain, and encoder. Lifting motor is equipped with brake, featuring small size, light weight, high efficiency, low noise and high stability. It will lock when power is off, the striker will not accidently fall down. Compared with steel wire rope, chain features small elasticity with precise height measurement. Also chain has higher strength with little abrasion, and safer than wire rope. Motor is mounted at the bottom of the main frame, easy to mount and service.
Striker release/clamp device
It is specially design and will automatically lock after clamping the striker. This device won't open caused by gravity even when the power is off. It is equipped with approach switch to detect the position. If striker is not clamped, crosshead won't move.
Specimen auto-feeding device
It is designed of four-bar linkage structure and pneumatic driving, featuring fast specimen feeding in only 5 seconds with high accuracy and simple operation. Meanwhile, it has auto center-aligning function. Only put the specimen onto this device, press the button on the control panel, this device will automatically feed the specimen onto the anvil and align the center, without labor work, improving efficiency and safety. After finishing impact, this device will push the specimen out with simple operation and high reliability.
