Spring Balancers

Spring Balancers to Improve Productivity

Spring Balancers

Hasemer Spring Balancers have a number of safety features and are user friendly, eliminating the chance of accidents, unlike older design Spring Balancers which had limited safety provisions, and were prone to operational hazards and industrial accidents leading to injuries.

When properly installed, the tool or piece of equipment becomes almost weightless for the operator making it easier and safer to use. Able to support weights up to 180kg and with stroke lengths up to 2.5m, Hasemer Materials Handling’s range of spring balancers can fit your needs.

Hasemer Spring Balancers are now available in a newclosed body concept to ensure better safety.

HWF Series

HWF series balancers are fully enclosed & are provisioned with a body liner to prevent damage to body.

HWA Series

These balancers are provisioned with wire arrest mechanism, which locks the drum pulley in case of tool disengagement. These balancers are available for capacity from 9 – 70 Kg. & have all the feature of SWF balancers as well. These balancers are primarily used with welding guns and applications where chances of wire slitting or tool disengagement due to accidental failure are higher.

Prior to the safety initiatives and modifications undertaken older design Spring Balancers had only limited safety provisions, due to which these oldertype Spring Balancers were prone to operational hazards and industrial accidents leading to huge compensations.

Several safety features have introduced into our new designed Spring Balancers while retaining all the existing safety features.

Hasemer Balancers have thus become more user friendly, eliminating chances of accidents.

Existing Safety Features Retained:

SAFETY PIN: Stops and locks drum pulley in the event of spring failure and thus prevents the fall of costly equipment and injury to the operator fromfalling load.

ADDITIONAL EYE: For fixing secondary support chain remains.

 

Exclusive Safety Feature Introduced:

1. ENCLOSED BODY

Some other branded spring balancers are supplied with openings both in the body & cover causing an accidental crunch of operator’s fingers between the revolving drum and the body of the spring balancers. To help prevent this occurring, side windows on the body and cover have been eliminated.

This would prevent industrial accidents.

 

2. WIRE ARREST MECHANISM (SWA SERIES)

In the unfortunate event of accidental dislodging of the suspended weight, and breakage of the bottom hook / wire rope, the spring tension will pull back the wire rope. The Hasemer Spring Balancer mechanism will lock the last revolving drum pulley, and the wire rope assembly will be stopped with a maximum 20cm travel. This will prevent the whipping of wire rope assembly & avoid any injury to the operator or any other personnel in the vicinity.

 

3. BODY LINER

In order to prevent wear of the slot of the Spring Balancer body, a split type nylon liner for wire rope has been introduced in the Hasemer design Spring Balancers.

This liner can be removed and installed on site without any need for dismantling of the wire rope.

This will prevent wear of the costly body resulting in overall savings and reduced production down time of equipment.

 

4. EASY ADJUSTMENT OF SPRING TENSION

In some other manufacturers’ spring balancers, the worm gear box for adjusting the spring tension works in the horizontal axis.

The gearbox position has been rotated through 90 degrees, so that spring tension adjustment can be made by working in vertical axis. This will facilitate adjustment from ground level without any need to rise up to spring balancer hanging level. This reduces down time, facilitates easy operation and reduces the chance of any mishap occurring whilst an operator rises to the level of the balancer.

 

5. WIRE ROPE REPLACEMENT WITHOUT DISMANTLING

A small slot is provided to facilitate removal and re-installation of the wire rope without any need for dismantling of the spring balancers. This reduces the down time of the equipment.

Note: This feature is not available for long range Spring Balancers.

 

6. CONTAINERISED SPRING ASSEMBLY

No longer do you need to handle open springs which are difficult and dangerous to handle with sharp edges. All springs are now supplied in concealed containers for easy replacement. This means containerised springs accidents are avoided during maintenance and replacements of springs.
