INTRODUCTION

• 1-1 This manual provides the Description, Operating Instructions, Installation, Theory of Operation, Maintenance and Troubleshooting Instructions for the Raymond Model 20 SCR trucks. Figure 1-1 shows a Model 20 Reach-Fork truck.
• 1-2 The Model 20 power lift truck is primarily built for general indoor warehouse use, or for bulk storage outdoors on paved ~r other hard surfaces. The truck is a stand-up rider type designed for narrow aisle installations. Right angle stacking of palletized loads can be accomplished in aisles as narrow as 6 feet.
• 1-3 Power for the Model 20 SCR truck is provided by a 24 volt industrial battery. The Model 20 truck has the ability, for example, to carry a 2,000 lb. load at speeds up to 5 miles per hour, to elevate at speeds up to 40 feet per minute, and to stack loads at heights up to 240 inches. These factors plus its exceptional maneuverability make the Model 20 truck the leading performer of 24 volt narrow aisle trucks.
• 1-4 Model 20 series trucks are available in 2000, 3000, and 4000 pound capacities and can be provided with straddle, reachfork, deep reach, scrambler low-lift platform and fork, 40 (four directional), high lift pallet, or sidereach attachments. The mast is offered in either two or three stage construction. A variety of collapsed and elevated heights are available to fit most applications. In addition, various optional features such as power tilt, sideshift, clamp, etc., adapt the truck to specific situations. Model 20 SCR trucks have, as a standard feature, U.L. type E approval. Type EE approval is optional.
• 1-5 Power steering is standard on all Model 20 trucks. Other conveniences which the trucks offer are a low step in compartment (only 11″ high) and the convenient location of the controls. Controls are located so the operator can drive facing either towards or away from the load. The operator controls steering with one hand while travel direction and speed, lift, lower, and auxiliary functions are all within easy reach of the other hand.
• 1-6 The Model 20 SCR truck incorporates the use of electronic semi-conductors to control travel speeds. This system provides the operator with an infinite selection of travel speeds, from slow inching to approximately 4½ miles per hour. The truck has a non-variable higher speed giving a top speed of 5 miles per hour.
