Tool Retractors & Balancers

One of the primary objectives of every company is to reduce costs while increasing productivity. Under these circumstances, ergonomics at the workstation are of the up most importance.

In making production and assembly procedures as convenient and as safe as possible, manipulating systems like Metreel Retractors and Balancers play a major role. Thanks not only to their outstanding positioning capabilities but also their exceptionally safe, durable design and construction, our products are ideal aids at the workbench.

Our range of Retractors and Balancers are all designed and made in accordance with the high quality standards laid down in the international standard DIN ISO 9001. Needless to say, all these products undergo exhaustive testing and bear the GS label of approval safety, as well as complying with CE requirements.

Metreel Retractors are designed in such a way that retraction force increases as the cable is extended. As a result the attached tool is returned to its starting position by the retractor after use, leaving the workbench free for other tools or items of equipment. An assurance of precision work is provided by the shallow rising graph representing the progressive increase in spring force.

Metreel Balancers are distinguished by their conical cable drum which ensures that the retraction force remains virtually 'constant', regardless of the cable travel. As a result, the position is retained after the attached tool has been used. In addition, no noteworthy increase in retraction force occurs when delicate operations are being performed. As a result, Metreel balancers permit fatigue-free working, even over prolonged periods of time.

Certain versions of retractors and balancers are fitted with an automatic arresting mechanism which stops the retraction process in a predetermined position, provided the attached tool is returned slowly. If the cable retracts rapidly, the arresting mechainism will not operate. This feature is particularly useful for example, if there is a need to prevent the tool from returning to its original starting position between individual work stages.

TYPES OF TOOL BALANCERS

Spring Balancers (Retractors)

Spring Balancers are designed so that the retracting force increases with increasing cable extension. Thus, the working load (tool) is automatically retracted to it's initial position after use, allowing the workspace to be used for other tools or devices. Precise operation is assured as the retraction force increases gradually and very smoothly.

Zero Gravity Balancers

Zero Gravity Balancers are characterised by the conical shape of their cable drum, which guarantees an almost constant retraction force independant of the extension of the load carrying cable. As a result, the working load remains suspended in the same position after use. Besides, no increasing retraction force acts upon the operator's hand, a significant advantage particularly for delicate, high precision tasks. Therefore, using a Metreel Zero Gravity Balancer minimises fatigue and facilitates your work over extened periods of time aswell.

TYPE 5200 - Light Duty Spring Balancer

This spring balancer, designed for loads infinitely adjustable between 0.5 and 2KG, is recommended for tasks where a tool needs to be kept in the 3rd dimension at a predetermined position. With a cable travel of 2m, this model provides sufficient range to allow the suspended load to be retracted to a predetermined position over larger distances aswell.

The use of special plastics for the housing and the cable drum, together with a selected special material for the spring, make this balancer model an ideal workplace assistant.

An easy to use and reliable retractor that is popular among users.

TYPE 7200 - Light Duty Spring Balancer

This balancer model is optimal for all light weight, hand operated tools that need to be kept ready in the 3rd dimension at predetermined position. With a maximum cable travel of 1.6m, this model provides ample working range for any application.

Thanks to the optimised, user friendly load setting procedure, the load capacity of these retractors can be adjusted very easily to working load weights (from 0 to 25kg – depending on the model used).

TYPE 7221 & 7222 - MEDIUM DUTY SPRING BALANCER

The 7221 type series has been designed for real continuous operation. IT is characterized by a very good, smooth retracting performance and a very large cable extension range of 3m, features that make it useful for all fields of application. With loads ranging from 2-14Kg these retractors easily meet the requirements posed by rough operating conditions.

Thanks to their quality and safety these balancers have stood the test, particularly with regard to the suspension of hand operated tools on assembly lines, but they are just as valuable for single applications or for installation in machines. Parts subject to wear such as the suspension spring and cable are easily replaced and available as spare parts.

This range comes with a spring fracture safeguard as a standard feature that reliably prevents the suspended load from crashing down if the spring breaks. Another standard feature is the safety chain, a fall prevention device that also significantly increases occupational safety.

This range has been optimised for easier load setting, now done with a continuously rotatable adjusting screw. These retractors incorporate a device that prevents inadvertent wrong operation (over rotation) during load setting, thus facilitating this process a great deal.

The 7222 features a ratchet lock. This automatic arresting mechanism allows the load to be suspended in a predetermined position if returned at a lower speed.

TYPE 7211 & 7212 - LIGHT DUTY SPRING BALANCER

This retractor provides perfect support when working with small hand operated tools of any kind, such as electrical or pneumatic tools, stitchers, nailers, manual scanners or labelling machines, measuring equipment etc. Adjustment to the desired load range is very easy, with optimized load graduations. An ample cable extension range of 2.5m is also provided.

The rugged design of the 7211 type series means dependable and low wear operation, with a long life being guaranteed even at a high cable extension rate.

The 7212 version comes with a ratchet lock. This automatic arresting mechanism allows the load to be suspended in a predefined position if moved back at a lower speed.
