Q1. How much number of limit switch on toer crane

Ans.

Tower cranes typically have multiple limit switches for safety purposes.

Tower cranes usually have 2-4 limit switches installed.
Limit switches are used to prevent the crane from overextending or overloading.
Examples of limit switches on a tower crane include hoisting limit switch, trolley limit switch, and slewing limit switch.

Ans.

I operate a tower crane.

I am trained to operate tower cranes specifically.
Tower cranes are commonly used in construction sites to lift heavy materials and equipment.
Tower cranes have a vertical mast and a jib that can rotate to reach different areas of the construction site.

Ans.

The capacity of the crane was 10 tons.

The crane had a maximum lifting capacity of 10 tons.
It could lift heavy materials such as steel beams, concrete panels, and machinery.
The capacity of the crane determined the maximum weight it could safely lift and move.

Ans.

The length of the crane was 80 meters.

Are these interview questions helpful?

Ans.

The tone of the crane is determined by the operator's communication with hand signals or radio.

The tone of the crane is typically communicated through hand signals or radio communication.
The operator must be able to understand and respond to the tone set by the signaler or supervisor.

Ans.

Safety devices on a tower crane include limit switches, overload sensors, anti-collision systems, and emergency stop buttons.

Limit switches are used to prevent the crane from moving beyond certain limits.
Overload sensors alert operators when the crane is carrying too much weight.
Anti-collision systems help prevent accidents by detecting nearby objects or other cranes.
Emergency stop buttons allow operators to quickly stop the crane in case of an emergency.

Ans.

F.T.C. stands for Free to Climb and G.T.C. stands for Ground to Cab. They are safety procedures for tower crane operators.

F.T.C. (Free to Climb) means the crane operator is free to climb up the tower crane to access the cab.
G.T.C. (Ground to Cab) means the crane operator must access the cab from the ground level using the designated access ladder or stairs.
These safety procedures help ensure that the crane operator safely enters and exits the cab without risking falls or inju...read more

Ans.

The length of the jib on a tower crane varies depending on the specific model and job requirements.

The length of the jib can range from 30 meters to over 80 meters.
The length of the jib is typically specified in the crane's technical specifications.
The longer the jib, the greater the reach and lifting capacity of the crane.
Different jobs may require different jib lengths to reach specific heights or distances.
