    Features of the TBL1000 Tree Shear: · Fastest cycle time available. · Made from 5/8 High Tensile Steel Plate. · Standard quick attach coupler or pin on couplers for skid steers, tractors, telehandlers, backhoes, wheeled loaders and compact excavators.

  • Pile Driving Part I: Introduction to Hammers and Techniques

    Vibratory Hammers. In the twentieth century, engineers in the former Soviet Union developed the first vibratory pile driver. This hammer was powered by a 28 kilowatt electric motor, and had a dynamic force of 214 kN. Through the 1950’s and after, the Soviets developed a variety of vibratory pile-driving hammers and soil drilling equipment.

  • Chapter 5: The Heavy Hammers of Pile

    3. Hydraulic Hammers: Driving in Pipes, Concrete and Timber. These are the most modern type of pile driver used in construction today. By using hydraulics, these hammers drive pipes, concrete and even timber deep into the earth. They also cause less environmental damage than diesel hammers because they are: More efficient; Generate less pollution

  • Pile Driving Basics, Common Problems, and Solutions

    Anatomy of a Pile Driver. At a high level, a pile driving system has four main parts: lead, hammer cushion, helmet, and pile cushion. Each part has a role in transferring energy to the pile which in turn impacts hammer performance. Read more at our glossary. Lead. The pile driver lead is a supporting framework that guides the pile and hammer.

  • US7404449B2

    There are a variety of pile driving machines currently known in the industry. There are simple drop-hammer pile drivers that use a cable, winch and crane to raise a mass above the pile and simply let the hammer free-fall onto the top of the pile (also known as the pile head), as illustrated in U.S. Pat. No. 4,660,655 (Wilner).

  • Vermeer PD10 Pile Driver

    To answer the need for quick-working, accurate equipment, Vermeer has developed the robust, productive PD10 pile driver. The PD10 has been specifically designed to meet the tight tolerances demanded by commercial solar contractors and the expansive solar fields they install. Over the past several years, renewable energy sources – like solar

  • Pile Driving Analyzer® (PDA) for High Strain Testing | Pile

    This functionality allows for extreme pile testing flexibility. Improved data transfer makes it easier to test hydraulic hammers with high blow rates. PDA tests are performed during driving on pilot or production piles, taking advantage of the high strain impact provided by the driving hammer.
