Product Description

Product Description

High damping rubber bearing, also called HDR bearing pad, is one of seismic isolation bearing. It has excellent seismic isolation performance to effectively reduce the bridge damage caused by earthquake.

HDR bearing pad is composed of specialized designed rubber with high damping performance, sandwiched together with steel plate layer. When installing, the high damping rubber bearing is commonly used with top and bottom steel plate and connection accessories.

Working principle

During earthquake, the vibration from various directions will impact fixed base building and results in deformation and building or bridge damages. The high damping bearing pad is improved through high damping material, which the damping ratio can approach to 15% to 18%.

When the earthquake comes, the high damping rubber bearing will increase the horizontal displacement through rubber shear deformation and reduce friction coefficient. The large displacement can weaken the vibration from all direction and reduce the damage of building and bridges.

HDR (I) bearing rubber	15%
HDR (II) bearing rubber	12%
LNR bearing rubber	10%

Feature

• Excellent horizontal displacement. absorb shock energy effecively.
• Excellent reset structure. there is no residual displacement.
• High damping material. 10% to 18% damping capacity for shock absorption.
• Wide range structure for different environments and displacement requirements.
• Economical and high performance for lower total construction budget.
• Easy installation and replacement for lower maintenance cost.

Application

High damping rubber bearing is widely used in the quake-prone areas for bridge, building and other constructions.

Packaging & Shipping

Packaging for Bridge Rubber Bearings:

Plastic Film Wrapping: Each rubber bearing is individually wrapped in plastic film to protect it from moisture, dust, and physical damage during transit.
Palletization: The wrapped bearings are then placed on pallets for stability and ease of handling. Palletization also facilitates the use of forklifts and other materials handling equipment.
Strapping or Banding: To secure the bearings on the pallet, strapping or banding may be used to prevent shifting during transportation.

 

Transportation of Bridge Rubber Bearings:

Sea Freight Containers: For international shipments, sea freight is a common method due to the ability to handle large quantities and the cost-effectiveness for heavy and bulky goods like bridge rubber bearings.
Container Selection: Depending on the size and quantity of the bearings, appropriate container sizes (such as 20' or 40' standard containers) are chosen to optimize space and ensure safe transportation.
Container Loading: The palletized bearings are carefully loaded into the containers, often with additional securing measures like wooden blocks or braces to prevent movement within the container during sea transport.
Customization: Transport methods can be adjusted to meet customer requirements, including alternative modes of transport such as air freight or land transportation if sea freight is not suitable.
