The Mitchell Tie Tamper attachment handles spot maintenance tamping needs and effectively reduces track maintenance cost.
The Mitchell Tie Tamper attachment is designed to fit Loader Backhoes and Excavators. The Tamper is manufactured of high strength steel to be strong enough for up to mid-size Excavators and light enough for Backhoe Loaders. The tamper is capable of tamping railroad track and carrying out a full insertion, squeeze and removal of tamping head at one side of the tie, swing to the opposite side of the tie, with full insertion, squeeze and removal of work head in less than 60 seconds. Thus, a production rate of 60 ties per hour (single squeezes) can be achieved.
The Tamper can be manufactured to fit a quick coupler or direct pin fit so the attachments can be attached and removed quickly. The unit has 4 tamping tools with a common vibrating unit. The tamper head can be manually rotated to tamp ballast on track of off track. Then the tamper can be hydraulically rotated 45 degrees so is can be easily aligned over the rail. The tamping tools are capable of inserting a depth of 21 inches beneath the rail level.
The tamping unit can vibrate the tamping tools at 70-110Hz with a tip displacement of 3/16 inch, and generate a down force of 300 lbs. per tool. The tamping tools can squeeze the ballast under the tie with a force of 675 lbs. per tool.
