Learn the purpose of bored-pile concrete spacers, how they support reinforcement-cage positioning and which project criteria should guide selection.
Selection Principles
The correct choice should follow project requirements rather than a single universal dimension or product type. Geometry, reinforcement layout, load, compatibility and site conditions should be evaluated together.
Practical Checks
Inspect dimensions, connections, stability and compatibility before use. Where load capacity, concrete pressure or lifting is involved, manufacturer technical documentation and the project design sho..

Formwork vibrators and immersion poker vibrators both compact concrete, but they transfer vibration differently.
Formwork vibrator
A formwork vibrator is attached externally so vibration passes through the formwork into the concrete.
Immersion vibrator
An immersion or poker vibrator places the vibrating head directly into fresh concrete. Head diameter is selected according to reinforcement spacing and concrete section.
Which system is suitable?
The correct method depends on formwork design, access, reinforcement density, concrete volume and project requirements.
Shoulder-type and high-frequency concrete vibrators compact fresh concrete but differ in mobility and working arrangement.
Shoulder-type vibrator
The motor unit moves with the operator, making this format practical when frequent movement around the jobsite is important.
High-frequency vibrator
High-frequency poker vibrators are available with different head diameters and are suited to planned concrete-placement work where head size and working range are important.
Which one should you choose?
Choose based on mobility, reinforcement spacing, concrete volume, head diameter and expected duty cycl..
Table scaffolding is a modular shoring system used below reinforced-concrete slabs and deck formwork. It can be assembled from a limited number of standard components and reused on repetitive floor cycles.
Main components
Typical components include frames, cross braces, adjustable base spindles, four-way heads, interconnectors and locking pins. H20 timber beams can be used above the shoring system as part of the slab-formwork structure.
Frame sizes
Current product information includes 110, 120, 150, 180, 200 and 220 cm frame sizes. Adjustable heads and bases are used to achieve the required wo..
If a concrete vibrator motor runs but the poker head does not vibrate, the problem is often somewhere in the mechanical drive path between the motor, coupling, flexible shaft and vibrator head.
Common causes
Typical causes include a worn or disconnected flexible shaft, a damaged coupling, a crushed hose or a worn vibrator-head mechanism. Intermittent vibration and unusual mechanical noise also require inspection.
When to stop using the machine
Stop operation if vibration disappears, the hose is visibly damaged, the head overheats or abnormal metallic noise develops. Continuing to run a faulty ..
Choosing a concrete vibrator requires more than comparing motor power. Head diameter, reinforcement spacing, concrete section thickness and pour volume should all be considered. This guide compares the 50, 58, 60, 65 and 80 mm high-frequency models listed by Cazip Fiyatlar.
Why Does Vibrator Head Diameter Matter?
A larger head can be useful in wider and thicker concrete sections, while a smaller head may be easier to use through tighter reinforcement. The correct choice is therefore the size that matches the application rather than simply the largest available model.
Model Overview
..
A concrete vibrator helps compact fresh concrete, reduce trapped air and improve placement around reinforcement and formwork. With intensive site use, the flexible hose, inner shaft, vibrator head, bearings and motor connections can wear over time.
What Does a Concrete Vibrator Do?
The vibrator head is inserted into fresh concrete and transfers high-frequency vibration into the mix. Correct use helps concrete settle more uniformly and reduces the risk of large voids. Excessive vibration should also be avoided because it can contribute to segregation.
