“I’m sorry; it’s just too steep and challenging. Our tractors won’t make it up that terrain.”

This statement has been made by countless excavating companies to potential employers. However, one company that is safely equipped and looking for the challenge is Truckee’s Dyer All Terrain Excavation.

Dyer All Terrain Excavation was established by Russ Dyer in October of 2012 and to date has been hired for several dangerous jobs using a Walking Mobile Excavator.

On April 20, 2013 in Munich, Germany, Bauma (the top international forum for showcasing groundbreaking developments in machinery and equipment for construction, building materials and mining) presented the Bauma Innovation Award to Kaiser AG for their Walking Mobile Excavator.

According to the speakers at the presentation ceremony, “this winning innovation fulfill[s] to an impressive degree the criteria upon which the high-caliber jury made their selections, namely: holding great promise for the future; practicality of application; contribution to environmental protection and to humanization of the workplace; and energy-and cost-efficiency coupled with performance,” (

The Spider Excavator (as it’s nicknamed) can work with maximum mobility on a 45° slope and can work in water (up to 5 feet), swamps and in rough, hardly accessible terrain. Because of its brilliant design using wheels and legs instead of tracks, the machine has a very low ground impact. The machine actually climbs in addition to driving. This is essential when working in sensitive areas. Due to the efficiency of the English motor, the Spider needs a minimal amount of fuel to run.

Fully biodegradable hydraulic fluid is used in the machine to protect the environment. A bucket tilter, clean up and digging bucket, grapple bucket, hydraulic breaker, mulcher and winch are some of the attachments that a Spider uses when working in all terrains.

Recently, Dyer All Terrain Excavation was hired for a job in Taos, N.M. In six weeks, Russ and his Spider excavated nine tower footing locations, a top terminal footing, a 150’ by 30’ unloading pad, footings for a ski patrol building, a hole for a one winch cat pick point and 3,000 feet of power line conduit for the lifts at the bottom terminal. In addition to this, Dyer completed all backfilling operations.

For a company that looks forward to challenging terrain, the horizon is the limit. Dyer All Terrain Excavation looks forward to expansion and future scheduled projects.
