Material Handling Devices

Objective: To be able to use tools and equipment effectively and safely to move farm materials.

Background

Hand Trucks

• Wheelbarrows, dolly trucks, and two-wheeled hand trucks are all hand trucks.
• Two-wheeled hand trucks can lift and transport heavy, bulky objects short distances.
• Work gloves and safety shoes should be worn.
• Hand trucks should be equipped with canvas, leather, or rubber knuckle guards to help prevent hand injuries.
• When loading, the heavy objects should be below the lighter ones, and the load kept as low as possible.
• The hand truck should not be overloaded, and the load should not obstruct your view.
• Use proper lifting techniques (Refer to “Preventing Lifting and Overexertion Injuries” training module) when lifting a load.
• The operator should push and balance the truck always walking forward.
• The truck should not be held in place with your foot. Two-wheeled hand trucks should be equipped with brakes.

Conveyors

• Generally, conveyors used in industry are roller, belt, screw, bucket, chain, overhead trolley, portable, mobile, tow, or assembly types.
• Moving parts should be guarded with wire mesh enclosures or railings.
• Rollers or pulleys at the ends of belt conveyors should be guarded to prevent fingers and hands from being drawn into pinch points.
• A shield, guard, or housing should enclose each end and all other areas at floor level where workers could come in contact with moving parts.
• Avoid riding on conveyors, except those that incorporate platforms and control rooms for operating personnel.
• Conveyors should have conveniently located warning devices and emergency stop controls.
• Turn off power and lock the switch during maintenance.

Powered Industrial Trucks

• Powered industrial trucks move material quickly and easily, and save work and time.
• Know how to safely operate the trucks and to correctly react to every situation.
• Pay attention to maximum load limits and the condition of the bed—never overload.
• Check brakes, steering, controls, forks, hoist, warning devices, and lights before and after each shift and report any malfunctions to supervisor.
• Back the truck down a ramp, but keep the load in front when going uphill.
• Tilt the forklift masts back when driving the lift and keep head, arms, and legs inside.
• Keep the forks about 4–6 inches above the ground.
• Do not lift people.
• Sound the horn at a blind corner.
• Check clearances when loading or unloading.

Cranes and Derricks

• Only trained operators are permitted to run cranes.
• The rated load must be plainly marked on each side of the crane and the crane must never be overloaded.
• Never work or stand underneath a crane that is moving material.
• If operating, do not swing loads over workers.
• Keep hoisting chains and ropes free from kinks.
• Use a load block hook with a sling—do not wrap chains or ropes around loads. Operators should make sure the sling clears all obstacles.
• Standard hand signals for boom cranes should be understood by both the operator and the signaler. (Refer to “Hand Signals” training module).
• Crane operators should never remove their hands and feet from the controls while a load is suspended.

Review The Following Points

• All employees should be trained before operating machinery.
• Watch for coworkers when completing work tasks.
• Make sure all loads are balanced when moving.
• Keep all screens and safety shields in place.
• Use standard hand signals for communication.
