We construct the wall-concreting vibrating body from die-cast aluminum, making it lightweight and durable. Being small, this unit can move flexibly in cramped corners and easily work on surface-finishing columns, walls, and other structures even on worksites on poorly-conditioned ground.

Both the EKCA and EKD can be combined with a special-purpose holder that enlarges the vibrating surface in the vibrating unit. This enlarges the effective range of vibration, thereby reducing working time. The holder is optional.
