SR WIRE ROPE HOIST

BRAND: SR

SR Wire Rope Hoist represents a revolutionary new generation of exceptionally reliable electric wire rope hoists, featuring advanced technology and cutting-edge performance combined with the latest in manufacturing and materials technology.

It is metric capacity rated, heavy-duty, has higher lifting speeds, and precise positioning control demanded by industry worldwide. Unique features included low maintenance, sealed brakes, a single or two-speed hoist motor, and a trolley to meet a wide variety of application requirements.

FEATURES:-

Hoist Motors:
Parallel solid rotor, high torque squirrel cage motors designed specifically for hoisting applications, allowing 45% ED and 240 starts per hour as standard. With 60% ED, 300 starts per hour are available. Class F insulation is standard. Higher insulation classes are achievable for specific applications.

Inverter e-Drives Traversing:
State-of-the-art flux vector drives provide stable load holding at all hoisting speeds. Dynamic braking and controlled acceleration provide smooth load handling with a minimum of wear to the hoist mechanism.

Hoist Brake:
Single disc, fail-safe electromechanical brake, energized separately from the motor, with direct current to ensure a positive action. Fitted directly onto the hoist gearbox input shaft, the brake provides greater safety than traditional motor-mounted brakes. Factory-set torque needs no adjustment. Requires minimal maintenance but is positioned for easy monitoring.

Gearbox:
Comprises a fully enclosed oil-immersed, triple-reduction gear train with SNCM21 for maximum wear resistance and strength. All shafts are supported on high-quality rolling element bearings for quiet, efficient operation and maximum life. Drive to the box is via a flexible coupling and NCM4 shaft drive.

Rope Drum:
Precision machined to ensure strength and rugged durability compared to casting. All steel drums are mounted on heavy-duty precision ball bearings.
