Proven Engineered Products – Complete Material Handling Solutions Two powerful industry leading brands—Link-Belt® and Syntron®— have come together under a new company name, Syntron Material Handling, LLC, for one goal – better engineered products. Although we may have a new name, we still have the same dedicated employees and industry leading engineered products that make us a market leader. Established in May 2014, Syntron Material Handling (SMH) was built out of the legacies of Link-Belt Company and Syntron Company, formerly owned by FMC Technologies. Today, our 300 skilled employees have...

Purpose This book is provided by Syntron Material Handling as an aid to answer common questions relating to vibratory equipment isolation. Proper wire rope and various hardware items will be reviewed to ensure the installation will allow the vibratory equipment to perform properly. The purpose of this book is to discuss the recommended methods for installing vibratory equipment isolation systems. It will address both suspension and base mounting along with the installation of safety cables. Since most vibratory equipment is suspension mounted, it will be the primary focus. In addition, the...

Base Mounting Base mounted vibratory equipment sits directly on some type of isolation spring, which can be either steel coil, polymeric, or pneumatic. These springs are then mounted on seats which attach to stationary support structure. The support structure must be designed to withstand: the static unit weight as shown on the equipment general arrangement drawing(s), the static material weight, the horizontal dynamic weight and the vertical dynamic load. If the previously listed weights or loads are not known, contact Syntron Material Handling. Spring Seats In addition to the static and...

Snubbers and Tag Lines On some base mounted brute force feeders and screens it is necessary to install snubbers. This is usually a spring-loaded device which rubs against pads on each of the four corners of the vibrating equipment. These snubbers are designed to help reduce side motion. Due to certain installation conditions, some suspension mounted brute force feeders and screens experience unwanted side motion and sway. In these situations, it is customary to install tag lines (see below tag line drawing). However, consult Syntron Material Handling prior to installation. Vibrating Unit...

Suspension Mounting Suspension mounted vibratory equipment hangs from isolation assemblies which are attached to the overhead stationary support structure. The support structure must be designed to withstand: the static unit weight as shown on the equipment general arrangement drawing(s), the static material weight, and the vertical dynamic load. If the previously listed weights are not known, contact Syntron Material Handling. support structure can be lighter and the probability of structural frequency problems is significantly less. Note the orientation of the suspension bails in the...

Wire Rope and Hardware Syntron Material Handling recommends the use of flexible wire rope for suspension mounted vibratory equipment as the best way to attach the isolation hangers to the rigid structure. The wire rope should be 6 x 25 (6 x 19 class) filler wire yellow strand preformed IWRC core right lay regular lay or equal pre-stressed to avoid stretching. The recommended wire rope size is as shown on page 19 of this book and in the service instruction manual for the specific equipment. Extra heavy wire rope thimbles and drop forged clips should be used and installed per the clip...

Suspension Cable Whip In some situations, even when the vibrating equipment is suspended with the proper wire rope, the wire rope will whip. This whip is usually caused by either improperly adjusted tension or by the natural frequency of the wire rope assembly being too close to the operating frequency of the vibrating equipment. Whip is usually associated with cables that are quite long. If the suspension wire rope assembly whips, the first step is to check for even loading on all suspension points. If one point is not adequately loaded the suspension hanger will not isolate and will cause...

Turnbuckles and Rods Syntron Material Handling does not recommend the use of turnbuckles or rods. Turnbuckles are generally used to make initial installation of equipment easier or to make slope adjustments to the vibratory equipment. However, the potential problems may far outweigh any perceived benefits. capacity should be achieved through the use of a variable control. If it is easy to adjust, it is easy for the unit to accidentally contact the stationary structure and damage will result. Furthermore, after initial installation the turnbuckles should be pinned and locked. This will make...

Safety Cables Syntron Material Handling recommends the use of safety cables on all suspension mounted vibratory equipment. The wire rope should be 6 x 25 (6 x 19 class) filler wire yellow strand preformed IWRC core right lay regular lay or equal. The recommended wire rope size is as shown in the service instruction manual for the specific equipment. Extra heavy wire rope thimbles and drop forged clips should be used and installed per clip manufacturer recommendations. If shackles are required, Syntron Material Handling recommends drop forged anchor type safety shackles (Crosby style...
