GENERAL
The DinkMar Inc. has an under-carriage hose support system that

Provides maximum overhead clearance when operating the suction hose on any DinkMar Inc. leaf Vacuum machine.

 

 

CONSTRUCTION
The Under-Carriage System is designed for heavy-duty use.  The Under-Carriage System is attached to the Blower Housing by (3) 1/2” diameter Grade-8 Bolts for easy attachment and removal.  The framework for the Under-Carriage System is constructed of 3/8”and  3/16” HRS plate.  The A-frame support construction is electrically welded to form a box arrangement that supports (2) in-line 4-bolt, flange bearings.  The bearings support a 1 1/4” diameter shaft.

 

The swing arm of the Under-Carriage System is attached to the 1 ¼” diameter shaft by a universal joint type connection, which allows free and easy movement of the suction hose in a horizontal plane.  A hydraulic cylinder operates vertical movement of the suction hose.  A “Thumb Touch” switch located on the operating handle of the suction hose controls this cylinder.

 

 

The support for the suction hose is a “cradle” constructed from ¼”Materiual of Flat Bar, Round Rod Stock and is capable of retaining suction hose from 12” to 18” diameter.  This cradle is operated by the 2” x 16” hydraulic cylinder.  The hose is retained in the cradle by a quick acting, nylon ratchet strap clamp.
