NBW series Electro-hydraulic storm braking wedge
Application:
| 1. Outdoor middle- and large size crane and port handling machinery; |
| 2. Anti-storm under crane cooperation state and auxiliary anti-storm under crane non-operation state |
Main Feature:
1. With limited switch, interlocking portection can be obtained.
2. All hinge points are fittled with self-lubrication bearing, so that there are high transmission efficiency, agile movement and long service life
3. With manual release function, maintenance is convenient.
4. It adopts Ed thrustor as actuator that had excellent performance, reliable sealing and high protection class of enclosed and with lowering delay function, impact on wedge acted by gantry is avoided The wedge is treated with special technique and it has high friction coefficient and excellent anti-corrosion performance.
Others:
In accordance with the demand of the customers and the actual overall dimensions, the given dimensions can be adjusted Electro-hydraulic thrusters can be rotated by 90 degree for installation.
Service conditions:
1. Ambient temperature: - 20 ºC - + 50 ºC;
2. Generally used for three-phase AC power supply: 380V, 50Hz;
3. The altitude of the place of use meets the relevant provisions of gb755-2000;
4. Technical parameters: windproof capacity of single windproof iron wedge brake (converted into horizontal force F);
5. F = f * n wheel (n wheel is wheel pressure; F is friction coefficient = 0.46) the number of complete machine to be installed is s = 2.5pw/f (PW is wind load = ckhqa) see lifting design specification.
Product selection:
1. Specific model and lifting capacity of accessory products;
2. Lifting height (distance from hook center to ground);
3. Working conditions: working environment, lifting objects, etc;
4. There are design drawings.
