Equipment

Parallel Hook Movement Device

Maintains a constant hook and boom head during boom extension and retraction. This reduces the risk of severed wire rope while the boom is moving.

Hook Over-winding Prevention Device

Reduces the risk of severed wire rope caused by over-winding the winch.

Hook Dimensions

*The dimensions shown are reference values.

Safety Lamps

Outrigger post safety lamps turn on to warn people nearby.

Multi-operational Lever

The crane and auger can be operated using the two multi-operational levers. Changing between operational levers is no longer necessary, which means better work efficiency.

Winch Drum

The use of a grooved drum prevents snagging and ensures smooth spooling.

Pole Extractor

Used for extracting poles. Comes equipped with dedicated hoses and slinging chains.

Oil Cooler

Cools hydraulic oil that has increased in temperature during continuous high-load operations.

Extendable Auger

The auger can be extended by up to 1.92 m in five stages.

A-type softrock tooth tip, RN6-type bedrock tooth tip

Can be selected and switched based on the surface of the drilling path.
*Other product lineups are also available.

Features

Reduced risk of damage to rotation device
When a large load presses on the basket, the hydraulic rotary actuator in the basket rotation mechanism releases the load and decreases the risk of damage.*Damage may occur when force is applied at rotation end and/or past rotation angle.
(SR12C1SM only)

Improved safety devices
The system uses a bar-type touch switch, which can correspond to basket deformation and is more reliable than the previous wire-type switch.

Improved engine maintenance
The gull-wing cover and swing-out engine base make maintenance and cleaning easier.

Reduced contamination and damage
The standard protective boot for the upper balance cylinder protects the cylinder rod from dust and welding spatter.

FEATURES

Reduced risk of damage to rotation device
When a large load applies pressure to the basket, the hydraulic rotary actuator in the basket rotation mechanism releases the load and decreases the risk of damage.
Applying force at the rotation end or beyond the rotation angle may cause damage.

Improved safety devices
The system uses a bar-type touch switch.. It can correspond to basket deformation and it is more reliable than the previous wire-type switch.

Improved engine maintenance
The design features a gull-wing cover and a swing-out engine base, which improve the ease of maintenance and cleaning.Engine slides out

Reduced environmental burden and improved fuel efficiency
New Tier 4 engine reduces environmental burden. In addition, engine speed control in accordance with workload increases fuel efficiency.
(Tier 2, Tier 3 engine can also be available)
