General-purpose Telescopic Mast System

Backed by diversified applications serving different use environments,
the operability of telescopic masts has been dramatically expanded.

General-purpose Telescopic Mast System[5m and below]

Highly durable with accurate position control. A quiet, compact system and structure.

YHW2204K/YHW2305J/YHW2305E

Ideal for camera photography and other applications requiring precision still positioning.

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.

The extremely quiet design also makes the mast ideal for use at night and indoors.

Mast extension and contraction are controlled via a htdraulic 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.

Highly flexible installation is possible even in tight spaces.

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.

Usage example

System configuration

(1)Standard Type
(2)Jack standard type

Hydraulic power unit

Hydraulic power unit that lifts and lowers the mast. Uses an inner rod system that has a low hydraulic fluid volume, anabling a compact system that requires little space.
Mast remote controller

Simple remote controller for lifting and lowering the mast. One-touch control for simple mast operation.
Simple space-saving unit

Mast raised and lowered using an all-in-one htdraulic 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.
Vehicle Stabilization 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.
Three-stroke valve(for dual cylinder)

A three-stroke valve for operating the vehicle stabilizing jack cylinders. Five-stroke valve when using four cylinders.
Jack remote controller

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 fron and rear jacks.

System configuration diagram images may differ from actual product.
Optional configurations such as the addition of a power switch are avaliable for the remote controller.
Optional configurations not listed here, such as the addition of a remote control cable relay, are also avaliable.
Choose from 12V DC, 24V DC, or 200-230 V AC for the power supply.
Pneumatic system also avaliable for telescopic mast. Contact us for details.

General-purpose Telescopic Mast System[5m and above]

Accurate and stable position control in high locations. Space-saving system configuration.

YHW2507E/YHW2609E/YHW2610F/YHW2710E/YHW2710D/YHW2712E/YHW2712D

Optimal for the wireless devices and transmission equipment that require stable operation in high places.

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.

The inner rod design enables a lightweight, space-saving system.

Even in masts with a longer maximum extension, the inner rod design enables a lightweight, space-saving system.

Does not require much space on compact vehicles or vehicles carrying a lot of other equipment.

The inner rod design uses a low amount of hydraulic fluid and uses a space-saving htdraulic tank.
Does not require much space on compact vehicles or vehicles carrying a lot of other equipment.
