Towbar Snubbers

Towbar Snubbers

Energy Absorption for Conveyor Applications 

ITT Enidine Inc. Hydraulic Tow Bar Snubbers provide features and benefits to extend the service life of inverted/overhead power and free conveyors by reducing the transmitted shock force encountered in the every day operation of the production line.

Hydraulic Tow Bar Snubbers manage the acceleration and deceleration (start/stop) of material handling systems by minimizing the shock forces transmitted to the structural components of the system.

ITT Enidine Inc. Tow Bar Snubbers reduce wear and downtime by absorbing high shock forces potentially transmitted into the moving carriage and its payload. These devices directly reduce maintenance costs associated with downtime and premature component wear.

FAQ

Can the OEM series shock absorbers be orificed for a specific application?

Yes. These shock absorbers can be orifice to provide specific damping for a particular application. When the shock absorbers are custom orifice they are referred to as CBOEM shock absorbers.

Does the HD model utilize a mechanical spring return?

No, the design incorporates an air charged bladder accumlator.

How are the OEM series shock absorbers adjusted?

The small series OEM shock absorbers can be adjusted by rotating the adjustment knob at the back of the shock absorber.

How do you determine whether an application will exceed 10 degrees(+/-5%) allowable angle?

The maximum side-load angle allowed by Enidine Incorporated is 10° (+5°). For a rotating arm, door, lid or circuit breaker for example, the moving load should be perpendicular to the center-line of the piston rod when it is halfway through the stroke.

How is the usable adjustment settings graph used?

Locate the applications impact velocity on the Y-axis and the selected model graph line. Follow the impact velocity horizontally until it intersects the selected model graph line. Follow the intersection point vertically down to the X-axis. The value at the X-axis is the maximum allowable adjustment setting.

Are there any accessories available for the OEM small series shock absorbers?

Enidine Incorporated offers a full assortment of accessories that include stop collars, jam nuts, cylinder clevises, foot mounts and cap pads. Not all accessories are available with all models.

How much additional energy capacity is obtained when using an Air/Oil tank?

Generally the shock absorber's energy capacity per hour can be increased by 20%.

What are DA units used for?

DA stands for double acting non-adjustable hydraulic damper. Applications range from doors and lids to amusement rides and conveyor systems.

What are the advantages of an Enidine Incorporated shock absorber over rubber bumpers and springs?

Longer Life - It significantly reduces shock and vibration to machinery.

Higher Operating Speeds - Machines can be operated at higher speeds because of the Shock Absorber control or gently stop moving objects.

Improved Production Quality - Harmful side effects of motion, such as noise and vibration and damaging impacts are moderate or eliminated, so the quality of production is improved.

Safer Machinery - Protects machinery and operators by offering predictable, reliable and controlled deceleration.

What are the most common names/types of shock absorbers?

Dampers, Buffers, Dashpost, Snubbers and Isolators.

What are the OEM small series shock absorbers?

The OEM small series shock absorbers are a series of adjustable shock absorbers that have bore siezes of 1/4 inch to 5/8 inch in diameter and stroke lengths of .28 inches to 2 inches depending on model.

What does HD stand for?

HD is the name of Enidine Incorporated's Heavy Duty series of shock absorbers.

What is a Towbar?

A specially designed DA which dampen abrupt starts and stops of power and free conveying systems.

What is an Enidine Incorporated CBOEM shock absorber?

CBOEM is a custom orifice non - adjustable unit, which meets specific application requirement.

What is Conventional Damping?

Allows linear deceleration by providing a constant shock force over the entire stroke.

What is Dashpot Damping?

This provides the largest shock force at the beginning of the stroke when the impact velocity is highest.

What is Progressive Damping?

This provides deceleration with a gradually increasing shock force. The initial minimal resistance at impact protects delicate loads and machinery from damage.

What is the adjustment range of the small bore OEM series shock absorbers?

The OEM small bore series shock absorbers have an adjustment range of 0 minimum damping to 8.0 maximum damping .

What is the charge pressure on an HD shock to be used?

Typically the HD models are charged at the factory to between 30 and 40 psi.

What is the standard operational temperature range of the OEM and PM/PRO series shock absorbers?

The standard operational temperature range is 15 to 180°F (-10 to 85°C).

What type of damping do the small bore OEM series shock absorbers provide?

The OEM .1 through .5 provide dashpot type damping. The OEM 1.0, OEM 1.25 x 1 and OEM 1.25 x 2 provide conventional type damping.

When should an Air/Oil tank be considered?

A. When the application's energy per hour exceeds the maximum rating for self contained units.

B. When the piston rod sequence must be controlled.
