Joystick Controls

Boom an bucket are operated by a

pilot-pressure controlled joy-stick.

(Option)

A single lever on the left side of the

steering column gives the operator

fast and easy control of speed and

direction. Push the lever forward to

drive forward, pull it back for

reverse. Travelling is automatically

changed from 1st stage to given

stage according to travel speed and

traction effort. The operator can

select two kinds of automatic

modes (1st<->4th, 2nd<->4th). This

exclusive feature contributes to a

step-up in productivity and

reduction of operator’s fatigue.

Engine control Unit (ECU), Trans-

mission control Unit (TCU) and

Machine control Unit (MCU) realize

the optimal performance through the

mutual CAN communications.

The Air Conditioning and Heating System

Up-to-Date-technology CAN System

Ride control is available for smooth travelling. It significantly reduces

machine bouncing and absorbs the shocks in the machine, enhancing

productivity. This system reduces the fatigue of the driver as well as the

stress on the structures and components.

Ride control system (option)

Control Center

The fully new, deluxe operating space was engineered by using 3-D modelling to

optimize drivers comfort. The wide, tinted and laminated front windshield has no

frame cutting through to ensure excellent visibility.

New Generation, Innovative Solution in Earth Moving, the

HL730-7A

The CUMMINS QSB4.5 electronic control

engine combines full-authority electronic

controls with reliable performance. The

combination of improved airflow and evenly

dispersed fuel results in increased power,

improved transient response and reduced

fuel consumption. Through the use of

advanced electronics, the QSB4.5 the engine

meets the emission standards EPA TierIII/EU

StageIII.

A Well Rounded System

Maximize your business productivity with HL730-7A.

With our vast experience in the production of construction equipment,

Hyundai is able to meet our customers demands.

Bucket cylinder guard

This guard helps to prevent possible

damage while loading material.

High-rigidity frames

Front and rear frames are designed

to work in the toughest conditions

and provide high rigidity for the

power train and loader equipment.

The sturdy frames, together with the

reinforced front/rear frame linkage,

resist loading stress and shocks

while in operation.

Axle

Inboard type brake discs.

2 Operating modes

BBeesstt eeccoonnoommyy mmooddee

Maximum fuel efficiency in

general loading conditions

MMaaxxiimmuumm ppoowweerr mmooddee

Maximum power output for

driving uphill and hard digging

conditions

Battery master switch

A master switch disconnects the battery power

to protect the electrical system from excessive

electrical drainage.

Sealed loader linkage

Fully protected fitting including dust seals and o-

rings on the bucket linkage will extend lubrication

intervals remarkably.

Frame lock

The machine can be locked by a locking bar to

prevent movement during transportation.

Multi Function Transmission

The newly developed transmission control represents the beating heart of transmission. The hydraulically operated

gear shifting with proportional valves allows precise clutch operation. For each gear change, the control unit

performs a monitoring function to ensure that the specified shift curve is adhered to, and readjusts the shift

pressure applied to the clutches accordingly. This result in smooth gearshifts under load without traction

interrupts. It also prevents standstills, sudden load changes or torque peaks during operation such as steep hill

driving with full load. In addition, there is the option for the driver to make manual gearshifts.

Accessible and Serviceable

New Generation, Innovative Solution in Earth Moving, the

HL730-7A

Accessible grease fittings

Grease fittings are highlighted and

centralized on the machine for fast

access when doing your service

checks.

Simple air filter

replacements

The air cleaner is easily replaceable

by turning the wing nut on the outer

shell counter-clockwise.

Open pin access

You can quicker remove or

tighten your front attachment

pin (chromated) with this open

connector system.

Remote type drain port

It is now easier to change your

engine oil, coolant and hydraulic oil

with the remote drain port located

near the rear axle of the machine.

IPhoto may include optional equipment.

HL730-7A_new_en 20-08-2007 11:10 Pagina 8

An ideal arrangement of components ensures easy access and convenience for maintenance.

A highly accessible engine compartment assures fast and efficient maintenance.

Hydraulic tank

The hydraulic tank is located behind the cab to facilitate accessibility of

hydraulic hoses and piping.

Oil sight gauge

A sight gauge is installed on the side

of the hydraulic tank for convenient

ground level check out.

Transmission oil port

The transmission oil change port is

openly accessible. It comes with an

anti-vandalism lock for machine

protection.

Centralised electric controllers &

Fuse Box

The electric controllers for this loader are

centralized together with the fuse box to improve

serviceability and facilitate inspections.

Cabin Air Fresh Filter

The internal pressure is maintained slightly higher

than that of outside to exclude dust from and

reduce noise level in the cabin.

Coolant Sight Gauge

A sight gauge is installed on top of the radiator

tank for convenient checks of the coolant level.

Easy Access to All Engine

Components

Up-to-date hydraulic remote

cooling fan

Here you find engine oil check and

main and pre-filters. The large

access engine-side-panels permit

easy and safe inspections. The fuel

and oil filters can be spun on and

off for quick replacements.

Minimum fuel consumption and

low noise is realized by using a

hydraulic cooling fan sensing

coolant temperature, intake air

temperature, transmission oil

temperature and hydraulic oil

temperature. Reversible cooling

fan is installed.
