Backed by diversified applications serving different use environments,
the operability of telescopic masts has been dramatically expanded.
Highly durable with accurate position control. A quiet, compact system and structure.
YHW2204K/YHW2305J/YHW2305E
Then highly durable mast achieves superior vibration and wind resistance, and the hydraulic system enables accurate position control.
Ideal for camera photography and other applications requiring precision still positioning.
Mast extension and contraction are controlled via a hydraulic power unit, achieving extremely quiet operation that makes the mast ideal for use at night and indoors.
When still, the mast is silent and requires no electricity, which means energy savings.
The entire system, including the mast, is lightweight, compact, and can be installed in tight spaces.
The hydraulic power unit is separate from the mast, achieving a space-saving design that provides a hight degree of freedom when choosing an installation location.





Hydraulic power unit that lifts and lowers the mast. Uses an inner rod system that has a low hydraulic fluid volume, enabling a compact system that requires little space.
Simple remote controller for lifting and lowering the mast. One-touch control for simple mast operation.
Mast raised and lowered using an all-in-one hydraulic tank and power unit. We reduced the unit size to achieve a space-saving design even in telescopic masts that require a large volume of hydraulic fluid. The addition of a valve is required to use a jack cylinder.
DJ2or4/SJ2or4/MJ2or4/LJ2or4
A hydraulic jack cylinder that prevents vehicle movement to stabilize the vehicle. Size and stroke can be chosen based on the vehicle type. Two types available:two rear cylinders or four cylinders front and rear.
A three-stroke valve for operating the vehicle stabilizing jack cylinders. Five-stroke valve when using four cylinders.
Remote controller for jack operation. In addition to ON/OFF control, the remote controller enables you to extend and contact left or right individually or extend and contract the entire unit. When using four cylinders, you can switch between front and rear jacks.

The highly durable mast achieves superior vibration and wind resistance, making it optimal for the wireless devices, transmission equipment, weather cameras that require stable operation in high places.
The hydraulic system enables quiet and smooth lifting and lowering, achieving accurate position control in high places.
Even in masts with a longer maximum extension, the inner rod design enables a lightweight, space-saving system.
The inner rod design uses a low amount of hydraulic fluid and uses a space-saving hydraulic tank.
Does not require much space on compact vehicles or vehicles carrying a lot of other equipment.








Mast raised and lowered using an all-in-one hydraulic tank and power unit. We reduced the unit size to achieve a space-saving design even in telescopic masts above 5m that require a large volume of hydraulic fluid. The addition of a valve is required to use a jack cylinder.
