INTRODUCTION

Based on an original design, TIRAK

wire rope scaf-

fold hoists are specially manufactured for lifting
personnel in a suspended platform system.

For that purpose they are UL classified.

TIRAK

hoists are composed of the fol-

lowing main assemblies (Fig. 1):

Wire rope driving mechanism

Gearbox

Air motor with primary brake

BLOCSTOP

BSO secondary brake, or

BLOCSTOP BS/BSO secondary brake

Air hose coupling

Control lever

Brake release lever

The main advantages of TIRAK

hoists are:

–

PowerfuI, fast, and lightweight.

–

Simple, rugged, and reliable.

–

Unlimited lifting height.

–

Constant speed on any height.

–

Gentle for its wire rope.

–

Mechanical emergency descent device.

The secondary brake (D) or (E), marked
BLOCSTOP

BSO or BS/BSO MUST ALWAYS BE

ATTACHED AND USED.

The original design requires, for safety and
efficiency, that it be used with a special TIRAK

wire rope specified by the Manufacturer

TIRAK

hoists are intended to be used for work

going up and down a vertical hanging wire rope.

TIRAK

hoists are designed to be rigged to a

compatible platform, workcage or bosun’s chair.

This manual gives the required information for
rigging, operating and maintaining the TIRAK

hoists. Responsibility for the complete suspended
platform system lies upon the rigger of that system.
