SIMPLICITY ,.. in Elwell-Parkers means fie outward simplicity and clean design of every Elwell- Parker truck reflect the inward simplicity of construction—a simplicity that pro- duces unusual strength and at the same time low maintenance costs. Take the Elwell-Parker drive unit, for example. A Brown and Sharpe worm and worm gear provide the simplest form of driving mechanism, requir- ing fewer bearings and fewer parts to wear. Because of the worm gear drive, right and left drive shafts are interchangeable in all E-P trucks. All wheels are mounted on oversize roller or ball bearings, so that drive shafts with universal joints may be drawn through the wheels. The lift jack is held in position by four bolts, so that by removing these bolts the whole unit can be taken out bodily. The lift unit is simplicity itself—and extremely rugged, too. Consisting of a brake, a motor, a worm and worm wheel, a safety clutch, a nut and a ram there are actually only three moving parts— nothing to get out of order—little to wear, even after years of service. No electric lift truck is better than its lift unit. Brake shoes are easily relined. The shoes, which surround surface-ground, drop-forged drums, are Low | Maintenance Costs readily lifted out by removing two nuts. Relining then becomes a simple matter. On tiering trucks and cranes the simplest type of winch and cable is used. Batteries are placed so as to be easily removed by sliding out of the battery compartment at either side, or by lifting out of the top. Complete attention has been given to simplicity of opera- tion, with full vision for the operator of the load and conditions ahead when traveling in either direction. All operating controls are placed in easily reached, natural positions. Elwell-Parker simplicity means lower operating cost, lower maintenance charges, a longer period of service and therefore a greater return on your. electric truck investment. The one way to make sure you get all Elwell-Parker advantages, includ- ing interchangeability of parts between types, 1s to specify Elwell-Parkeras the make of truck you buy.
