Static load vs dynamic loadbearing

Reduce the wear on your engine with new delayed engine shutdown, which can be scheduled to activate automatically by the operator. The intelligent function turns off the machine when the turbo charger has cooled down to the appropriate temperature, reducing component wear.

Minimize downtime and increase component life with easier access to the Boom Suspension System accumulators – now placed on the outside of the front frame – and P-brake, which is now external.

Customize your machine and ensure precise control of hydraulic functions, with the choice of single or multi levers. To get the most out of each operation, select from three hydraulic modes, according to your preferred responsiveness. To reduce operator fatigue and improve productivity, Comfort Drive Control gives you the opportunity to steer the machine from a small lever.

The Collision Mitigation System has been developed to support the safe operation of Volvo Wheel Loaders. The optional system assists operators while working in reverse by automatically applying the brakes when the machine approaches an obstacle, helping to reduce the risk or consequences of collisions and enhance jobsite safety.

Short-term age, in the sense of the least possible number of hours that should elapse between molding and subsequent evaluation, is also a significant factor affecting load deflection. Depending upon the nature of each particular product, this minimum period will vary from 24 hours to 168 hours.

Often, when making use of rubber, stiffness variation is not critical to the rubber product’s function, and in such cases, the Shore A durometer hardness specification is sufficient. But rubber is frequently used as an engineering material in applications like resilient mountings, vibration isolators, dampers, impact pads, and similar. In instances where static or dynamic stiffness characteristics become critical to a product’s function, appropriate test specifications must be instituted.

To enhance visibility, the L260H has new rear-view mirrors and can be equipped with a rear-view camera. Optimized by the radar detect system, which works with the camera to give a visual and audible alert to the operator of unseen on-coming objects. Orange handrails and steps have been placed on the machine, intended to stand out to the operators and maintenance staff.

The aging of rubber compounds over time is a complex process. The normal net effect of aging is an increase in modulus or stiffness. The magnitude of this change is dependent upon the specific material involved, as well as the environmental conditions to which it was subjected.

Get the most out of your L260H with our range of purpose-built attachments, perfect for applications such as quarrying, aggregates, mining and heavy infrastructure. Form one solid and reliable unit with attachments that are ideally matched by size and design to your machine’s parameters – including link-arm geometry, and breakout and lifting forces.

When applicable, the design engineer must specify method of test, spring rate, and load deflection along with associated tolerances. If damping characteristics are required as a part of a dynamic specification, commercial tolerances would be ±25% on parts up through 65 durometer hardness (SHORE A) and ±30% for parts above 65 durometer hardness (SHORE A).

Experience up to 5% greater productivity with the new 7.3 m³ (9.5 yd³) Volvo Rehandling bucket. The redesigned bucket is easier to fill and minimizes spillage, thanks to new convex sides and an improved spill guard. To prevent spillage and absorb shocks, opt for the Boom Suspension System, which automatically engages, depending on gear or speed selection.

For improved cycle times and greater fuel efficiency, customize the lock-up engagement of your machine with new generation OptiShift. The improved technology integrates the Reverse By Braking (RBB) function – patented by Volvo – and the new torque converter with lock-up, creating a direct drive between the engine and transmission, reducing fuel consumption.

Temperature affects spring rate. For a rubber product not under continuous tension: the higher the temperature, the lower the spring rate, and the lower the temperature, the higher the spring rate.

Designed with durability in mind, the L260H is built with a Lifetime Frame and Structure Warranty, including the front frame, rear frame, articulation joint and loader arm. The hydraulically-driven cooling fan regulates component temperature and automatically reverses, permitting self-cleaning of the cooling units.

Engineered for efficiency and productivity, the L260H is fitted with a powerful Tier 4 final engine, delivering 6% more power and 5% more torque than the L250H.

Where rubber is used as a vibration isolator, such applications are dependent upon the behavior of the rubber when subjected to these dynamic operating conditions.

When a static load-deflection specification is established for a product—in addition to a hardness requirement—the load-deflection specification shall supersede the hardness requirement. Additionally, the specification should be agreed upon by both the customer and the rubber manufacturer, and then be clearly stated on the product drawing. A static test is only “static” in that the load application comes to rest before the measurement is taken; or that the rate of deflection does not normally exceed 0.8mm/s (2 in/min). Such a test usually places the rubber in shear or compression.

The intuitive app provides real-time guidance to operators, helping them understand how their actions influence machine productivity and efficiency, as well as identify areas for improvement or changes in their technique.

Rubber and urethane provide greater deflection for applied forces than do rigid materials such as metals or ceramics. Most uses of rubber are based upon this characteristic. Urethane may be selected for the same attribute, in addition to its excellent impact strength and abrasion resistance.

When dynamic stiffness or spring rate is specified, and is also determined to be critical to the performance of the rubber product, the complete test conditions and methods of measurement must be clarified between customer and rubber manufacturer.

With the tire pressure monitoring app, you can check the condition of your tires from the comfort of the cab. Providing real-time information on tire pressure and temperature, the system saves time during machine inspections and can prolong tire lifetime.

The load-deflection characteristics of a rubber product are affected by its work history. For new parts, or parts that have been in a static state for a period of time, their initial loading cycles indicate a stiffer load-deflection characteristic than noted in subsequent cycles. In static testing, this effect becomes stabilized, and so the load-deflection characteristics typically become repeatable after two to four conditioning cycles. In dynamic testing, the conditioning period is usually designated as the amount of time necessary for obtaining reproducible results.

Save on machine wear and increase fuel efficiency with the eco pedal. Uniquely designed by Volvo, the eco pedal encourages economical operation, by applying a mechanical push-back force in response to excess use of the accelerator.

Do more with less fuel, thanks to a powerful engine and new generation hydraulics, which save hydraulic pump power for other functions, by reducing fluid flow when lowering and dumping. Coupled with the new dry P-Brake, which eliminates drag losses caused by the internal wet multi-disk brake.

Rubber is stiffer dynamically than when in a static mode; and since the static-to-dynamic stiffness ratio varies with individual compounds, it may be advisable to specify the dynamic characteristics of the rubber for usages of this manner.
