2.0 Definitions For the purposes of this Good Practice Guide, the following definitions apply:-

2.1 additive - a material which is added to concrete to change the properties of the mix

2.2 ball catcher - a device fitted to the delivery end of a pipeline designed to catch the sponge rubber device used for cleaning the pipeline

2.3 banksman - a person who has had training to give directions to the operator of a vehicle mounted concrete pump during manoeuvring of the vehicle on site, by a recognised code of signals or by verbal communication

2.4 blanking device - a component designed by the concrete pump manufacturer fitted securely at the outlet end of a placing or delivery hose with a coupling or other device to prevent concrete from falling out of the hose whilst the concrete placing boom is being moved to a new position

2.5 boom tip safety chain- a chain fitted to the end of the concrete placing boom which is attached to the placing hose and which is designed to retain the placing hose if the coupling attaching it to the boom pipeline fails

2.6 competent person - a person who has such practical and theoretical knowledge, experience and training as necessary to safely carry out the functions to enable him/ her to carry out his/her duties without risk to himself or any other persons and without risk of damage to plant or property NOTE: An example of a nationally and industry recognised training scheme for the operation of a concrete pumping machine (mobile or trailer) is the Construction Plant Competence Scheme (CPCS) or equivalent.

2.7 concrete - a homogeneous mix of cement, graded aggregate and water, to which non- toxic additives may be added

2.8 concrete placing boom - a device to support and position the delivery pipeline. It can incorporate folding, derricking and slewing motions

2.9 concrete pump -an item of plant used for pumping or spraying concrete. It works by pistons or a rotary pump, whereby the material to be transported is conveyed to the placing position through a pipeline alone or through a pipeline attached to a concrete placing boom.

2.10 delivery hose- a flexible hose used in the pipeline other than as a placing hose i.e... a double ended hose Safe Use of Concrete Pumps 6 September 2013

2.11 him, his and himself - can also mean the female equivalent

2.12 Hirer company, firm, person, corporation or public authority - taking the owner’s plant on hire, including their successors or personal representatives

2.13 inspection certificate - document containing the results of an inspection of the concrete pump by a competent person and including the details specified in Annex 6

2.14 interlock - a switch usually located on the hopper which prevents operation of the machine when activated

2.15 linesman - person supplied by owner or hirer trained to work with concrete delivery pipelines

2.16 Owner company -firm or person letting the concrete pump on hire, including their successors, assignees or personal representatives

2.17 pipelines or delivery lines - pipes, whether steel or rubber, through which the concrete is conveyed. They will include, pipes, bends, hoses, coupling connectors and any valves inserted in the line. Each element of the line must be capable of resisting the likely maximum pressure exerted by the concrete pump

2.18 placing hose- a flexible single ended hose to provide freedom of movement in the final placing of concrete

2.19 receiving hopper - the area into which the mixed concrete is discharged. It will generally contain the valve gear for transferring the concrete from the concrete pistons into the delivery line. It may also contain mixer paddles on a revolving shaft. Access doors and an interlocked protective grille must be fitted to prevent persons from coming into contact with the moving machinery

2.20 remote control box - a portable control panel which is connected to the concrete pump by a wired or wireless system, allowing the concrete pump operator to operate the machine from a remote position. The control levers / switches may operate the placing boom movements, the concrete pump and the vehicle engine

2.21 safety induction training -instruction given by the principal contractor or the Hirer to communicate the site safety rules, safe access on the site, the location of welfare facilities, etc. The provider of the training may determine that the delivery of induction training on the first visit to the site is sufficient but may insist on further training if site conditions change significantly Safe Use of Concrete Pumps 7 September 2013

2.22 signaller -a person who has had training to give directions to the concrete pump operator by a recognised code of signals or by verbal communication

2.23 sponge rubber cleaning device - a piece of sponge rubber, usually in the shape of a ball, which is inserted into the delivery pipeline for the purpose of cleaning the inside of the pipes. It is propelled along the pipeline either by the action of the pump (forward or reverse), by compressed air or by water pressure

2.24 stabilisers - extendible structural members on the pump unit to increase the dimensions of the stability base 

2.25 trailer-mounted concrete pump - a concrete pump that is mounted on a trailer that can be towed (also known as a static pump)

2.26 truck-mounted concrete pump- a concrete pump that is mounted on a self-propelled lorry

2.27 wash out adapter - a short length of pipe with one end blanked off and a connection for a water / compressed air hose for cleaning purposes. A secondary valve(s) should be fitted for releasing the pressure when necessary, also a working pressure gauge
