Product Description

Spring braking- Hydraulic release- Suitable for Disc Thickness of 30 mm
Advantages
1. Compact structure2. Large braking torque3. Easy installation
Applied field
Lifting transportation, metallurgy, mining, ports, construction machinery , cable sling equipment, wind turbines, textile machinery and other industries.
Use Condition
Environment temperature: -20ºC~50ºCThere is no flammable, explosive gas in the ambient.Air relative humidity is less than 90%.The altitude of the place of use is in accordance with GB755-2000.The anti-corrosion products should be used for outdoor rain and snow erosion or corrosive gas and medium.
Working brake

1. Allows the braking of the high frequencies.
2. Low maintenance costs,the brake compensation device(the stable braking torque) is equipped with pad wear , short respond time.
3. Mounting tolerances, brake disc face beats: max +/-0.2 mm. The vertical deviation of base relative to disc: max +/- 4%. The deviation from brake disc relative to the center of the base: max +/- 2.5 mm.
4. 3SH brake(hydraulic release). Hydraulic station should be matched when working.

Safety Brake

1. Large braking force, same with working brakes.
2. Used as an emergency brake in case of over speeding, Normally the static brake has short respond time.
3. Mounting tolerances, brake disc face beats: max +/-0.2 mm. The vertical deviation of base relative to disc: max +/- 4%.
4. Need power unit when working.

Technical parameters

Basic parameter	The brake torque(N.M)	Braking torque=force/1000(ΦB/2-68)
	Response time(S)	0.2
