SPECIFICATIONS

The Lodestar Electric Chain Hoist is a highly versatile materials

handling device that can be used to lift loads that are within its rated

capacity. The mechanical features of these hoists include an alloy

liftwheel, load-limiter, hardened steel chain guides, hardened steel

load chain, hardened steel gear train, life-time lubrication, forged

steel hooks, and lightweight aluminum frame. The electrical features

included hoist-duty motor, rugged hoist brake, magnetic reversing

contactor and voltage conversion board (dual voltage units).

Follow all instructions and warnings for inspecting, maintaining

and operating this hoist.

The use of any hoist presents some risk of personal injury or

property damage. That risk is greatly increased if proper instructions

and warnings are not followed. Before using this hoist, each operator

should become thoroughly familiar with all warnings, instructions,

and recommendations in this manual.

LODESTAR D8+

According to VPLT.SR2.0 and SQP2, D8 Plus chain hoists are used to lift loads during set-up and have the special characteristic of being

able to hold loads at rest above people, without using a secondary component. The Lodestar D8+ has a minimum of 10:1 design factor,

double brakes, and a clutch outside of the load path (when power is disconnected), per the requirements of the German Code of Practice,

VPLT.SR2.0.
