Build a System

Page 2 covers a checklist of 17 application questions. Let's review each question.

1. Can trucks that are not currently configured for side-removal be modified?

Multi-Shifters battery changing vehicles extract the battery out the side of the forklift. So, the battery must rest on a roller strips or Roller Strips
Roller strips consist of two strips of low profile, in-line rollers that support the battery and allow it to be removed horizontally out of the lift truck.

so it can be moved laterally.

Generally speaking, Narrow-Aisle Forklifts such as Reach Trucks, Order-Pickers, Stock-Pickers, Turret Trucks, Sideloaders, Pallet Trucks, come from the factory with battery side-removal as a standard specification. Usually, a roller bed is used in conjunction with a side gate.

If a truck is not configured for side extraction, a side-gate must be cut in the side of the truck's battery compartment.

This modification is not a problem with 4-wheel counterbalance forklifts. However, it can be a problem with 3-wheel counterbalance trucks. 3-Wheel trucks have a battery compartment that is much closer to the floor than 4-wheel forklifts. As a result, the battery sits down in a well.

Cutting the side of a 3-wheel truck's battery compartment takes out the steel that supports the structural integrity of the truck. Essentially, by cutting that much out of the sideof the truck, it would cause the truck to collapse.

3-Wheel trucks can be modified but the expense can be up to $2000.00 per truck. That can turn a project from a battery-handling vehicle project into a Gantry project.

2. Are poly-inserts required for any trucks? If yes, how many?

Any forklifts that have batteries resting directly on the bed of the battery compartment will need poly-inserts or roller-inserts for the battery to move across the compartment.

Poly-Inserts are used for batteries up to 3000 lbs. Roller-Inserts are used for batteries over 3000Lbs.

3. If trucks to be modified are sit-down counterbalance models, remove the battery, inspect the compartment, and view the motor access opening. Consider whether the Poly-Slide Poly-Slide Insert Strips
Poly-Slide Insert Strips are the most popular of the battery support strips. They are composed of a UHMW polyethylene bearing material with internal lubricants and are enclosed within a steel channel making them maintenance free.

or inserts will span over the motor opening. Note the access dimensions on the Multi-Shifter terminology page (page 4).

Many times, in the battery compartment there is open space above the drive motor. This creates a hole the inserts must span across. The inserts must be reinforced with steel bar so the insert will not collapse as the battery moves across the open space.

4. What is the overall length of the longest truck in the system including forks or attachments?

We need this dimension so we can properly size the Change Area in the system. The Change Area is the parking space for the lift truck during a battery exchange. It is usually located at one end of the system.

5. Are there any Sideloaders, 4-Directional, or 3-Wheel trucks in the system?

These types of trucks require some special options to work successfully in a side-extraction battery-handling system.

6.What are the numbers of shifts worked per day?

As we previously discussed, the number of shifts determine the number of batteries stored, which determines the amount of battery stands needed to store the batteries. It also determines the number of battery changes per day.
