Concrete delivery trucks
When delivering concrete the following should be ensured:
- Concrete delivery trucks should have clear and safe access to approach and leave the receiving hopper of the pump.
- Where more than one concrete delivery truck is required, the person in control of the workplace should ensure that a spotter or traffic controller is on site to direct the movement of trucks.
- The concrete delivery truck driver should have adequate room to operate the concrete truck safely and, in an emergency, be able to operate the concrete pump emergency shutdown device.
- No person should stand between the reversing concrete delivery truck and the hopper.
- Any vehicle reversing into the exclusion zone must stop immediately if the spotter or traffic controller is not visible to the driver.
- The concrete chute on concrete trucks should only be moved when the truck is stationary and undertaken by the driver or with the agreement of the driver.
- The concrete receiving hopper should be at a height that allows a gravity flow of concrete into the hopper.
- Additional ramping may be required for the concrete delivery truck where low slump concrete is to be used.
- Where ramps are used they should be designed so that the truck cannot back off the ramps, it remains stable and has a non-slip surface.
- All concrete delivery trucks should be fitted with reversing hazard lights such as an amber flashing light mounted at the rear of the truck.
- All concrete delivery trucks should be fitted with audible reversing devices.
For important information on the safe concrete delivery, check section 4.3.1 of the Concrete Pumping Code of Practice 2005.
When delivering concrete to the pump hopper you must protect workers and the public from risk of contact with moving parts by:
- Positioning hopper safely to receive concrete flow directly from discharge chute of concrete delivery truck.
- Provision of a grill to prevent access to dangerous moving parts such as feed or agitator mechanisms and valve gear.
- Bolting down the grill to prevent lifting or using a cut out switch designed to isolate the agitator shaft if the grill can be lifted.
- The emergency stop button must be able to reached by the concrete pump operator and the concrete delivery truck driver.
- Constructing parallel bars on the grill spaced at or below 75mm to reduce the risk of a person¿s hand being trapped.
- Ensuring that the distance from the top of the grill to any moving parts be at least 100mm.
