Safety marker
We achieved an improvement of
productivity and safety in the crane operation.
It requires considerable skills to move the crane hook promptly and accurately to center on top of load. An increased efficiency and manpower-saving are the keys to improve productivity at any manufacturing site.
The implementation of FUTEC ORIGIN's safety marker enables not only prompt and accurate positioning, but also to prevent damage on the load due to operation errors as well as angled hanging, all of which ultimately improves safety and saves labor of the ground workers.
Effect of implementing the safety marker
-
Improvement of work efficiency with better viewability
The safety marker not only enables prompt and accurate positioning of the hook, but also improves viewability of workers with clearer recognition of the work area and dangerous spots. This significantly improves the efficiency of crane operation. In addition, it has a profound effect in terms of technical support for unskilled crane operators.
-
Effective safety measures with improved viewability
With an improved viewability, the safety marker prevents damage on the load and angled hanging, reducing a risk of accident. It also decreases a risk of injury for workers allowing to achieve effective safety measures.
-
Prevention of damage on the load caused by operation error
Any damage on the expensive goods not only causes economic loss due to incurrence of repair/replacement cost and delayed delivery, but also leads to a loss of trust of customers. The improved viewability helps to mitigate damage risk and avoid a loss.
-
Manpower saving and cost reduction
With an improved viewability, operator is able to accurately recognize the work area and dangerous spots from a distance. This helps to eliminate ground workers (such as flag person) to save manpower. The human resources may be moved to other positions, leading to a cost reduction.
Usage Examples
The safety marker is usable on the shop floor in a variety of industries, including plants and warehouses.
-
Center mark of hoisting attachment
When hoisting scroll materials such as coil, the hoisting attachment must be exactly matched to the center of the hoisting object.
By visibly showing the center position to an operator, offset load can be prevented,
contributing to prevent accidents caused by load swing and unbalanced load. -
Judgment of length/dimension of long objects
The lengths of the pipes and steel bars can be judged during the transport without contact. Check the length by focusing the (linear) mark of the marker on both ends of the object.
-
Positioning of press mold
The safety marker is used in the mold changeover process among other precise tasks of positioning upper and lower molds of the pressing machine.
By adjusting the position using the marker, it prevents mold damage. -
Confirmation of loading location
The safety marker may be used to confirm whether the object is correctly located at a designated place when loading or allocating the load or products.
-
Determination of height and position of the coil
The safety marker supports the centering and positioning when the coiled material are placed on the uncoiler.
Also, it prevents the material being distorted or damaged in the uncoiling movement. -
C-hook handling aid
When transporting the coil, during hoisting operation using C-hook, the safety marker provides guide to the operator as to appropriate grasping position, preventing cargo from shifting and damaging the facility due to wrong way of hanging.
*The safety marker can be used in situations other than the above. Please consult with us about your concern.

"Safety marker", the industry-first small marker with LED light source
Characteristics of LM series
-
Use of LED light
High light intensity and high-viewability are achieved by adopting high-power LED.
With the power consumption as low as approx. 40w, this makes it possible to minimize the running cost. -
Compact size
It is small enough to be installed on small cranes such as hoist.
-
Long life
The lamp life is as long as 40,000 hours.
(*The value is an estimated life of lamp element, but not a product's guarantee time.) -
Select from 4 types
A user can select from 4 different types depending on the purpose and use conditions.
