You’ve decided to switch to slip sheets. You’ve got your slip sheets ordered.
Now you realize: You can’t handle slip sheets with a standard forklift. You need a push-pull attachment.
You start shopping and discover: Attachments range from $2,000 to $8,000+. Different types, configurations, and brands. Confusing specifications and claims.
Here’s your complete guide to buying push-pull attachments—what they are, how they work, what to look for, how much to spend, and how to avoid costly mistakes.
What Is a Push-Pull Attachment?
First, understand what you’re buying.
Basic concept:
- Hydraulic attachment that mounts on forklift forks
- Grips slip sheet with clamps or friction pads
- Pushes load onto slip sheet (loading)
- Pulls slip sheet with load off surface (unloading)
- Eliminates need for pallets
Main components:
- Platen (push plate): Flat surface that contacts slip sheet
- Clamps or grippers: Mechanism that grabs slip sheet edge
- Hydraulic cylinders: Provide pushing/pulling force
- Mounting system: Attaches to forklift forks or carriage
- Control valve: Operator controls for engage/disengage
How it works:
- Approach load with attachment
- Insert platen under load edge (on top of slip sheet)
- Engage clamps to grip slip sheet
- Pull load toward forklift
- Lift and transport
- Reverse process to unload
Types of Push-Pull Attachments
Different designs for different applications.
Type 1: Clamp-style (most common)
- Metal clamps grip slip sheet edges
- Positive mechanical grip
- Works with various slip sheet materials
- Most reliable and versatile
- Best for: General purpose, varied applications
Type 2: Friction pad style
- Rubber or urethane pads create friction
- Gentler on slip sheets (less damage)
- Requires clean, dry slip sheets for grip
- Less reliable in wet/dirty conditions
- Best for: Clean environments, delicate sheets
Type 3: Combination style
- Both clamps and friction pads
- Adjustable gripping method
- Most versatile but more complex
- Higher cost
- Best for: Operations with varied conditions
Type 4: Roller bed style
- Rollers on platen surface
- Reduces friction during push/pull
- Easier load handling
- More expensive
- Best for: Heavy loads, frequent handling
Capacity Considerations
Match attachment to your load requirements.
Load capacity ratings:
- Light duty: 2,000-3,000 lbs
- Medium duty: 3,000-5,000 lbs (most common)
- Heavy duty: 5,000-8,000 lbs
- Extra heavy: 8,000+ lbs
How to determine your needs:
- Calculate typical load weight
- Add 20-30% safety margin
- Example: 2,500 lb loads → 3,000-3,500 lb rated attachment
Cost vs. capacity:
- Light duty: $2,000-3,500
- Medium duty: $3,500-5,500
- Heavy duty: $5,500-8,000+
Don’t over-buy capacity (unnecessary cost) or under-buy (dangerous and damages equipment).
Platen Dimensions
Size of the push plate matters.
Standard platen sizes:
- 48″ wide: Fits 48×40″ and 48×48″ slip sheets
- 60″ wide: Larger slip sheets
- Custom widths available
Depth (front to back):
- 12-18″: Typical for most applications
- Deeper platens provide more support
- Shallower platens lighter and less expensive
Match to your slip sheets:
- Platen should be ≥ slip sheet width
- 48″ platen works for 48×40″ and 48×48″ sheets
- Don’t buy 60″ platen if you only use 48″ sheets (unnecessary cost and weight)
Mounting Options
How attachment connects to forklift.
Fork-mounted (slip-on style):
- Slides onto existing forklift forks
- Secured with locking pins
- Removable for standard fork use
- Lower cost
- Pros: Versatile, lower cost, easy on/off
- Cons: Less stable than integrated, limits fork use when mounted
Carriage-mounted (integrated):
- Bolts directly to forklift carriage
- Permanent or semi-permanent installation
- More stable and robust
- Higher cost
- Pros: More stable, better for heavy loads
- Cons: Dedicated equipment, higher cost
Quick-attach systems:
- Rapid connect/disconnect
- Best of both worlds
- Premium pricing
- Pros: Fast changeover, stable when attached
- Cons: Higher cost
Choose based on: How often you’ll switch between slip sheets and pallets, Load requirements, Budget.
Hydraulic Requirements
Ensure forklift compatibility.
Auxiliary hydraulics needed:
- Push-pull requires hydraulic power
- Forklift must have auxiliary hydraulic circuit
- Check: PSI rating (pressure), GPM rating (flow)
Typical requirements:
- Pressure: 2,000-3,000 PSI
- Flow: 5-15 GPM
If your forklift lacks auxiliary hydraulics:
- Can often be added ($1,500-3,000)
- Factor into total cost
- Some older forklifts can’t accommodate
Control options:
- Cable-operated (manual lever)
- Hydraulic pilot control (button)
- Electric solenoid (button)
Verify compatibility before buying attachment.
