Description

The Newer Wyco ErgoPack Backpack Concrete Vibrator W402-535 has been replaced by the W402-558 is the only backpack vibrator on the market to offer an ergonomic design where the engine weight is properly supported by the operator’s hips. The W402-535 has a few improvements including a light operating weight by 25% (click below pdf for details). 

UPDATE – we have rolled out this new website, but are working to get other details including pricing added to our site. In the mean time we welcome all phone calls for pricing. As of this writing we have this model in our physical stock and available for same day shipping for orders by Noon to avoid many of our online competitors delays and dependence on shipping from a backordered mfg (we can always ship this path like they do at the lower price also). 

Day Sale or when current inventory sells out with sale price for pkg setup only. Add $125 for backpack only and select “none” & “none” for head and shaft. 

This is the top of the line in comfort, productivity and quality in a backpack setup. The ErgoPack improves overall job site productivity by delaying operator fatigue, discouraging injury-prone postures, and ultimately making a hard day’s work just a little more comfortable.The Wyco backpack design provides for easy mobility around the jobsite and can allow one user to easily vibrate low to high slump concrete with up to a 2” head. A built in tachometer allows for quick reference of vibration speeds and allows users to take full advantage of the variable speed control to harness the most effective vibration for any mix. The Wyco Backpack is gear driven, rather than belt driven to eliminate the possibility of belt problems. Hardened steel gears further increase the durability of the unit.

Price includes Freight to a Business Address with offloading by Customer*

In our Physical Stock and available for same day shipping** Many of our competitors will be shipping direct from the mfg and the customer will have to wait for equipment to be shipped and then wait on economy shipping. If you need expedited shipping, please contact us for pricing. 

Shafts & Heads purchased separately. While Wyco suggests a 7′ or 10′ (includes quick disconnect) shaft for the backpack, a 14′ can be used with the purchase of a quick disconnect. The 1″ head option must be used with the small 14′ shaft W988-914 with a quick disconnect. The W989-914 is the larger 14′ shaft for the 1 3/8″ and 1 3/4″ heads.  The Priced Options include the Quick Disconnect. Please contact us if you have any questions.
