The rigging device which are used to move loads without the use of slings, but grip the load by biting down and using jaw tension to secure the load, is lifting clamps.
<h3>What are the rigging devices?</h3>
The rigging devices are used to lift the objects and items when the safety is required. This device is used in the industries.
Types of rigging devices
- Rigging hooks-These rigging device is used when the heavy load need to be lift.
- Lifting clamps-Lifting clamp are used to lift the device with jaw tension to secure the load. In this, there is no use of slings.
- Pulley and blocks-In the load is lifts with the help of block and pulley arrangement. This is a widely used rigging device.
Thus, the rigging device which are used to move loads without the use of slings, but grip the load by biting down and using jaw tension to secure the load, is lifting clamps.

Explanation:
A 75- kw, 3-, Y- connected, 50-Hz 440- V cylindrical synchronous motor operates at rated condition with 0.8 p.f leading. the motor efficiency excluding field and stator losses, is 95%and X=2.5ohms. calculate the mechanical power developed, the Armature current, back e.m.f, power angle and maximum or pull out torque of the motor
