BLOKCAM | Benedicto Steel





Using BlokCam, the hook block or boom tip of a crane may be rapidly and simply equipped with a wireless camera system.

Antenna systems wirelessly send and receive sound and video from a screen in the cab to the camera’s lower portion.

This gives the operator a clear view and sound of the load and the surrounding environment, allowing them to see and hear what they need to see and hear what they need to hear when working in the dark.



1 On the Boom Tip or Hook Block
The audio-visual information is captured by the sensor and sent to the transmitter. A repeater mounted on the Jib, Boom, or Cab transmits the signal. Both the Transmitter and the Sensor are powered by the same battery. Each part is magnetically attached and can be put on the block, including between the cheek plates and on the boom tip.

2 Repeater on the Jib/Boom and/or Cab
The wireless signal from the transmitter is received by the Repeater and sent to a monitor in the cab through the Repeater. The crane type, jib/boom type, and jib/boom length all have an impact on where and how the Repeater is mounted.

3 Inside the Control Room
As a result, the operator is able to see and hear what’s happening underneath the camera thanks to the live audio-visual feed being processed and displayed within the cab.


Reducing the Risk of Injury
Uncontrolled loads striking workers in the region surrounding the hook block generate a disproportionately high number of crane-related injuries (21%). After installing the BlokCam camera, operators can now see and hear what is going on around them to avoid any accidents.

Reducing Anxiety
Long hours in tough conditions, especially in all kinds of weather, can add to the already high levels of stress experienced by crane operators. Verifying radio communications using BlokCam helps to ease the stress of this task by providing a visual image of the load and site regions that confirms the load’s security, balance, and any risks that may exist underneath or around the load.

Reduce the number of collisions and impacts.
It is getting increasingly difficult for crane operators to place their loads in confined spaces on modern construction sites, which are growing increasingly congested as buildings rise. Impacts and crashes are as likely, if not more so, than before. BlokCam’s clear and uninterrupted audio-visual feed helps the operator to respond to any adjustments to eliminate any potential incidents before they occur, enabling for a safer and more productive lift.

Confirming Load Security
BlokCam allows the operator to view and hear the load and surrounding area, confirming the balance and security before starting the lift. This confirms the communication with the banks-men and also helps keep the utilisation of the equipment to a maximum without any delayed lifts and re-slinging. Rigging/Slinging failures account for 10% of crane-related incidents.

Communication has been improved.
It is now possible for the crane operator to have eyes and ears on the cargo, the site, and the surrounding area from a distance. This allows the banksmen, slingers, and signallers to communicate with each other in a more controlled atmosphere, and it improves their capacity to communicate more quickly and effectively.

The BlokCam Reduces the Lift of the Blinds.
Oftentimes, blind lift accidents occur when the operator is fully reliant on radio communications, which might fail for a variety of reasons, causing delays in the message and perhaps causing an accident. When using BlokCam, operators can see and hear what’s going on around the load below their hook, reducing the blind lift.


Enhance Lifting Speeds
To boost speed and accuracy in all situations, BlokCam provides a close-up view of what’s below the hook and in the surrounding region, providing the operator additional situational awareness. Improved lift efficiency and faster work completion will result from this change. Many man-hours were saved as a result of this improvement in productivity, and the use of equipment was better managed.

Assistive Hands
Additionally, the BlokCam system installed as a visual aid for positioning the hook block in order to function in tandem with radio directions from banks-men/slingers, complimenting and confirming correct positioning while maintaining a steady flow of lifting jobs that serve to boost production.

Observed Factors
Having a camera system installed on a crane can enhance production by up to 39 percent in the blind and 27 percent in the open, according to a university study published in the Journal of Construction Engineering and Management.

In terms of the bottom line,
Lifting jobs become more efficient and productive when BlokCam is installed on the site, since improved communication and enhanced safety all contribute to this improvement. This project’s lifting plan will benefit greatly if you can lower the blind lift, eliminate any corrections or overshoots, and enhance the overall bottom line.

Corrections and Modifications
By providing visual and aural information, situational awareness, and aid in communicating with the banksman, BlokCam enhances the operator’s experience and makes it useful in high-risk lifts. To drive a car while wearing a blindfold and being guided by the passenger is a dangerous and stressful experience in its own right. It’s easy to envision how much safer and more efficient a motorist can be without a blindfold: In order to reduce errors and overshoots and increase production, the operator is able to immediately make the necessary modifications.



Blokcam, a camera developed for mobile and crawler cranes, can be installed in less than five minutes and is compatible with a wide range of cranes


Tower cranes can be fitted with Blokcam in less than an hour, allowing you to see and hear what’s going on around you at all times.
