Description of accessories
Load Chain
The load chain is designed for a long service and maximum safety. It is made of
surface hardened, zinc plated and blue chromated high grade special steel.
The load chain needs lubrication before use and on regular intervals, see the
Warnings and Maintenance sections.
Chain collectors
The chain collectors are reinforced with PVC cloth or sheet steel.
Chain stop
A chain stop can be fitted to stop the hoist at a predetermined position.
Safety hook
A safety hook (cannot be opened under load) can be fitted for additional lifting
safety.
Overload protection device
The overload protection device can be fitted to avoid unintentional hoist over-
load. When the hoist is overloaded, the device automatically reduces motor out-
put.
It is supplied as a standard for lifting capacities of 1 000 kg, 2 500 kg and 5 000
kg. The overload protection device is an Optional accessory for loads below
1 000 kg.
Controlling the hoist
The hoist can be controlled in three different ways; Standard, Twist rod or Pen-
dant.
• Standard chain control
Standard versions of LLA hoists include a chain control handle.
• Twist rod control
Twist rod control offers the highest level of precision. Adjustable length (1
to 2 meters) or for special extension rod (up to 5 meters).
• Pendant control
Remote Pendant controls are used to extend the operating area up to 10 me-
ters from the hoist. Atlas Copco offers two versions; a two–button unit for
hoist or trolley control, and a four– button unit for hoist and trolley control.
Both are equipped with a safety stop button.
Horizontal mobility with Trolleys
Explosion proof trolleys for risk free horizontal mobility are available in narrow
or wide, manual or motorized versions. They are flexible and simple to install.
They are also equally suitable for parallel or tapered I–beams and easily ad-
justed to different widths.
