1. Do not attempt to lift or hold any load that is greater than these lift capacities at their
specified lift point radius and heights. Weight of all accessories must be deducted from theabove lift capacities.
2. Lift capacities are based on machine standing on level, firm, and uniform ground. User must
make allowance for job conditions such as soft or uneven ground, out of level conditions,side loads, sudden stopping of loads, hazardous conditions, experience of personnel, etc.
3. Bucket lift hook defined as lift point.

4. The above lifting capacities are in compliance with ISO 10567. They do not exceed
87% of hydraulic lifting capacity or 75% of tipping load. Lifting capacities marked with anasterisk (*) are limited by hydraulic capacity rather than tipping load.
5. Operator should be fully acquainted with the Operator’s and Maintenance Instructions
before operating this machine. Rules for safe operation of equipment should be adhered toat all times.
6. Lift capacities apply to only machine as originally manufactured and normally equipped by
KOBELCO CONSTRUCTION MACHINERY CO., LTD.

Now KOBELCO has taken the next evolutionary step by packing even more digging power and practical performance features into the SK35SR/SK50P while maintaining a short tail swing. The new Energy Conservation Modesaves even more fuel, and KOBELCO’s proprietary iNDr Cooling System ensures protection from dust and easy
maintenance.

Visual Checking and Easy
Cleaning

Fuel Saving

Because the iNDr filter removes dust
from the intake air, cooling components stay dirt-free and do not require
regular cleaning. The iNDr filter itself
can be easily removed and cleaned
without the use oftools.

Energy Conservation Mode

Comfortable Work
Environment

The SK35SR/SK50P adapts S mode
which enables 25 % (23 %: SK50P)
less fuel consumption compared withH mode.

Spacious Work Environment

Operator Safety
Reliable Cab/Canopy Structure

Broader floor space and a greatersliding range for the seat give operators plenty of foot room. Wide operational space is provided with moreroom between the left and right control consoles.

TOPS and TOP GUARD LEVEL 1(SK35SR)

iNDr Filter
The stainless-steel filter is extremely
effective against dust, with 30-meshwave-type screen that removes tiny
dust particles from the intake air.

25% less fuel consumption
SK50P: 23% less fuel consumption
SK35SR:ROPS and TOP GUARD LEVEL 1(SK50P)

Color Liquid Crystal Monitor(Optional)
The color crystal monitor is fitted asoption. Operation data
as well as the full rangeof machine-status data
can readily be checked.

Protection from Dust and Easy Maintenance
The iNDr filter fitted in front of the cooling system ensures easy cleaning. TheiNDr system on the SK35SR/SK50P features air intake at the front of the machine and air exhaust underneath. It functions in the same way as the iNDr
System on the SR series machines.

•30-mesh means that there are 30 holes formedby horizontal and vertical wires in every squareinch of filter.

Two-speed travel function automatically shifts into Low Mode when aload is applied.

KOBELCO’s unique blade design
solves this problem by forming theearth into an arc that always falls forward.

A larger boom and arm are provided
as standard equipment to ensure awider working range.

The compact tail swing improves operating efficiency in limited space.
