What is 
CAP BALANCER?

heavy lid get lighter

No more heavy lids!
CAP BALANCER

This product is Spring-assisted hinge for opening and closing heavy or large lids of pressure vessels, reaction kilns, stirring tanks, and various tanks lightly and safely.

Cap balancers are spring-assisted hinges that can safely and lightly open and close heavy lids such as reaction vessels, agitation tank manholes, and filter housing covers.
To meet the increasingly sophisticated safety requirements of manufacturing sites in recent years, we also offer a free-stop type that can hold the lid stationary at any angle and a type that can be attached to large lids weighing 100 kg or more.

It be mounted on a variety of equipment.

It can be easily mounted to the equipment in use, and the desired lightness can be achieved by adjusting the torque.
With a track record of more than 20 years since its release, it has been used in many plant facilities in Japan and abroad for chemical, pharmaceutical, food, and other industries.

3 improvements achieved with CAP BALANCER!

  • POINT 01

    Easy to open and close

    When a cap balancer is attached to a heavy lid, it becomes surprisingly light and can be opened and closed easily.

  • POINT 02

    Improved safety

    It eliminates the risk of fingers getting caught in heavy lids or falling on poor footholds.

  • POINT 03

    Improved operational efficiency

    Lids and covers can be opened and closed quickly and smoothly, improving time efficiency.

So much lighter! Savior of heavy lids

  • CAP BALANCER Spring Assisted Type

    CAP BALANCER
    Spring Assisted Type

    It can open and close even heavy lids lightly and safely by spring force. It assists opening and closing of heavy lids and covers. It can
    open and close

  • CAP BALANCER Free Stop Type

    CAP BALANCER
    Free Stop Type

    Compared with Spring Assisted Type, Free Stop Type has the following features.

    Features of
    Free Stop Type

    • It can hold the lid stationary over a wide range of openinng angles.
    • It has enhanced lateral strength, to reduce lateral misalignment.
    • It is waterproofed inside the spring case.

    *If the center of gravity of the lid is high, the range of angles at which the lid is stationary may be smaller.
    *For free stop type, calculate the torque of the lid more accurately.

    When the torque of the lid is matched with the torque of the spring, the heavy lid can be restrained at any angle.

Development, Engineering & Design

BACKGROUND
Background of Development

To solve problems 
in opening and 
closing heavy lids

Many manufacturers have produced spring-assisted hinges for lightly opening and closing heavy lids.
Among them, hinges using torsion coil springs can be relatively compact and can be installed in equipment with limited installation space.
The cap balancer was developed as a torsion coil spring type hinge that can handle a wide range of torques from small to large and is easy to maintain, including spring replacement.
The weak points of the torsion coil spring type were the phenomenon of the cap lifting up when the cap is closed and the inability to hold the cap still at an arbitrary angle. However, the free stop type has solved these problems.
