Flat (Large-Sided) Clamp in UAE

Why use a flat clamp instead of forks?

Forks need a pallet, skid or fork pockets under the load. Many large boxed and crated goods are not delivered that way, and adding pallets costs money, takes height in containers and creates pallet returns.

A flat clamp grips the load from the sides instead. It can pick loads from tight stacks, place them against walls or other loads with no fork gap, and load containers more densely. It also avoids fork damage to the bottom of crates and cartons.

How a flat clamp works

1. Open the arms wider than the load.
2. Approach square to the load so both arms sit flat against opposite faces.
3. Close the arms. A pressure relief valve limits the clamping force to the set value.
4. Lift, then use the side-shift function to line the load up with its destination.
5. Lower the load fully before opening the arms.

Some designs move both arms equally; others have one fixed and one moving arm. Friction pads on the arm faces increase grip without extra pressure.

Typical loads and applications

• Home appliances: Refrigerators, washing machines, freezers and televisions, singly or in stacks.
• Crates and boxes: Wooden crates, metal stillages and boxed machine parts.
• Furniture: Flat-packed and boxed furniture moved without pallets.
• Container and trailer loading: Packing goods tightly with no pallet space lost.
• Warehousing and logistics: Palletless storage of large, uniform boxed goods.

Typical flat clamp specifications

Exact arm dimensions, opening range and attachment weight must be taken from the manufacturer's data.

Flat clamp, carton clamp or bale clamp?

The categories overlap. The load's rigidity, surface and weight usually decide which is right.

How to choose a flat clamp

1. Record the weight of the heaviest load, including any stacked together.
2. Measure the narrowest and widest loads to set the opening range.
3. Measure load height and length to size the arms so they cover enough of the load face.
4. Assess how rigid or fragile the load is, which sets pad material and clamping pressure.
5. Decide whether loads are handled singly or stacked.
6. Check the forklift's capacity, carriage class and number of auxiliary hydraulic functions.

Capacity and compatibility

A flat clamp is heavier than forks and holds the load further from the carriage, so the forklift's residual capacity is lower than its rated capacity. Available capacity must be confirmed from the forklift's load chart together with the clamp's weight and load centre, and the capacity plate must reflect the truck and clamp combination.

The truck needs two auxiliary hydraulic functions: one to clamp and one to side shift. Clamping pressure must also be set for the load: too low and it can slip; too high and it can crush cartons or dent appliance panels.

Safe use

Only clamp loads that are strong enough to take side pressure. Keep the arms square to the load, never lift a load gripped only at its corners, and lower before releasing. Check pads for wear, as worn or contaminated pads reduce grip. Operators should be trained on clamp attachments, because a dropped clamped load gives little warning.
