Which eyebolt below is used for angular loading?
-
Shouldered
-
Non-shouldered
-
Alloy
-
Answer option 4
Correct Answer
A. ShoulderedExplanation
A shouldered eyebolt is used for angular loading because it has a shoulder or collar that provides additional support and prevents the bolt from rotating under load. This design is specifically intended for applications where the load is applied at an angle, as the shoulder helps to distribute the load evenly and prevent damage to the bolt or the surrounding structure.Rate this question:

Which hook is used on alloy steel chain slings?
-
Sliding hook
-
Eye hook
-
Grab hook
-
Answer option 4
Correct Answer
A. Grab hookExplanation
A grab hook is used on alloy steel chain slings because it has a specific design that allows it to securely grab onto the chain links, providing a strong and reliable connection. This type of hook is commonly used in lifting applications where a secure attachment point is needed to prevent the load from slipping or coming loose. The grab hook's design ensures that it can effectively grip the chain links, making it a suitable choice for use with alloy steel chain slings.Rate this question:

Screw pin
-
Round pin
-
Straight pin
-
Answer option 4
Correct Answer
A. Screw pinExplanation
The most widely used type of shackle is the screw pin shackle. This type of shackle is commonly used in various industries and applications because it is easy to use and provides a secure connection. The screw pin can be easily unscrewed to open the shackle and then screwed back in to lock it in place, ensuring that the load or equipment being secured remains safely attached. Screw pin shackles are versatile and suitable for a wide range of uses, making them the preferred choice for many professionals.Rate this question:

Which system is used to operate a chain hoist?
-
Gear
-
Hook
-
Sprocket
-
Answer option 4
Correct Answer
A. GearExplanation
A chain hoist is operated using a gear system. The gears in the system help to increase the force applied to the chain, allowing for heavier loads to be lifted with less effort. The gear system also provides control and precision in lifting and lowering the load.Rate this question:

To calculate the total sling stress applied during a lift, you need to know the angle at which the sling will attach and _________________________________.
-
The total weight of the load
-
Rate at which the load will be lifted
-
Wind speed and direction
-
Answer option 4
Correct Answer
A. The total weight of the loadExplanation
To calculate the total sling stress applied during a lift, you need to know the angle at which the sling will attach and the total weight of the load. The angle of attachment affects the distribution of the load on the sling, with higher angles increasing the stress on the sling. The total weight of the load is crucial in determining the magnitude of the stress on the sling. Both factors are necessary to accurately calculate the sling stress during a lift.Rate this question:

Which type of hitch should be used to lift a bundle of pipes?
-
Double-wrap choker hitch
-
Single-wrap choker hitch
-
Straight vertical hitch
-
Answer option 4
Correct Answer
A. Double-wrap choker hitchExplanation
A double-wrap choker hitch should be used to lift a bundle of pipes. This type of hitch involves wrapping the lifting sling twice around the bundle and then passing the end of the sling through the choker eye. This creates a secure grip on the bundle, preventing it from slipping or shifting during lifting. Using a single-wrap choker hitch may not provide enough friction to hold the bundle securely, and a straight vertical hitch may not distribute the load evenly, leading to instability. Therefore, the double-wrap choker hitch is the most suitable option for lifting a bundle of pipes.Rate this question:

When should wire rope slings be inspected?
-
Before every use
-
Once a year
-
Once a week
-
Answer option 4
Correct Answer
A. Before every useExplanation
Wire rope slings should be inspected before every use to ensure their safety and reliability. Regular inspections help identify any potential damage or wear and tear that could compromise the integrity of the sling. By inspecting the wire rope sling before each use, any issues can be addressed promptly, reducing the risk of accidents or failures during lifting operations. This practice aligns with standard safety procedures and regulations to maintain a high level of safety in the workplace.Rate this question:

When should someone inspect eyebolts?
-
Once a day
-
Once a year
-
Once a month
-
Answer option 4
Correct Answer
A. Once a yearExplanation
Eyebolts are commonly used for lifting heavy loads, and their safety is crucial to prevent accidents. Inspecting eyebolts once a year ensures that they are in proper working condition and can bear the required load. Regular inspections help identify any signs of wear and tear, such as corrosion or deformation, which could compromise their strength. By conducting annual inspections, potential issues can be detected early on and necessary maintenance or replacement can be carried out to ensure the continued safety and reliability of the eyebolts.Rate this question:

Two or more slings attached to the same hook.
-
bridle hitch
-
Vertical hitch
-
Master link
-
Answer option 4
Correct Answer
A. bridle hitchExplanation
A bridle hitch is used when two or more slings need to be attached to the same hook. It allows for equal distribution of weight and prevents any one sling from bearing the entire load. This hitch is commonly used in rigging and lifting operations to ensure stability and safety.Rate this question:

To navigate loads we use what?
-
Hand signals
-
Automated cranes
-
Signs
-
Answer option 4
Correct Answer
A. Hand signalsExplanation
Hand signals are used to navigate loads in situations where verbal communication or automated systems may not be feasible or safe. This method involves using specific hand gestures or movements to convey instructions or commands to the crane operator or other personnel involved in the load navigation process. Hand signals are commonly used in construction sites, warehouses, and other industrial settings to ensure safe and efficient movement of loads.Rate this question:

You should use two double-wrap choker hitches when lifting a load longer than ______ feet.
-
12
-
6
-
10
-
Answer option 4
Correct Answer
A. 12Explanation
When lifting a load longer than 12 feet, it is recommended to use two double-wrap choker hitches. This is because a double-wrap choker hitch provides additional support and stability to the load, reducing the risk of it slipping or becoming unbalanced during the lifting process. Using two double-wrap choker hitches distributes the load's weight more evenly and helps to prevent any potential damage or accidents that could occur if only one choker hitch was used.Rate this question:

A sling has been _______________ if the tattle-tail has been pulled into the jacket.
-
Overloaded
-
Overheated
-
Crushed
-
Answer option 4
Correct Answer
A. OverloadedExplanation
If the tattle-tail has been pulled into the jacket, it indicates that the sling has been overloaded. This means that the weight or load on the sling has exceeded its maximum capacity, causing it to become strained or damaged.Rate this question:

Who are the only people allowed on a landing zone?
-
Tag line tenders
-
Supervisors
-
Load navigators
-
Answer option 4
Correct Answer
A. Tag line tendersExplanation
Tag line tenders are the only people allowed on a landing zone. A tag line tender is responsible for controlling and guiding the load during helicopter operations. They ensure that the load is properly attached to the helicopter and assist in maneuvering it to the desired location. Their presence on the landing zone is crucial for the safe and efficient execution of helicopter operations. Supervisors and load navigators may have important roles in the overall operation, but they are not specifically designated to be on the landing zone.Rate this question:
