Product Specications and Operational Environment

Standard Specications

ISO 4301 specifies the total operating hour (service life) of gears and bearings according to the loading status. For example,

the total operating hour (service life) of the mechanism for M5 constantly subjected to the rated load is 1,600 hours. The total

operating hour reaches 6,300 hours under a medium load.

*Rate of loading

Light : A case where the capacity is rarely applied. Usually the hoist is used with a light load.

Medium : A case where the capacity is applied considerably frequently. Usually the hoist is used with a medium load.

Heavy : A case where the capacity is applied considerably frequently. Usually the hoist is used with a heavy load.

Ultra heavy : A case where the capacity is applied constantly.

After unpacking, confirm chain stamp, and make a record of serial number and an inspection

as shown below.

•Be sure to check that the Load Chain is for the electric chain hoist ER2. The Load Chain of

other models (such as model ES or ER) or for different capacity cannot be used.

Failure to use a proper chain may result in death or serious injury due to the drop of the lifted load.

Mandatory

The load chain identification stamp (RH-DAT) is indicated on at intervals of chain links. Make sure that the Load Chain is

of a chain size (wire diameter) appropriate for ER2 referring to the table below.

DANGER

●For later maintenance or inspection, at the time

of unpacking, fill in the table in the right with the

dimension "a" between embossed marks on the

Bottom Hook, the width of the hook "b" and the

thickness of the hook "c". (These values are used

for checking. Please also record the value for the

top hook of ER2 when your product is suspended

with a hook.)

■Recording the Initial Value

•The each type of Chain Container has the capacity to store the specific amount of the Load

Chain. Use the Chain Container in correct capacity.

An chain overflow from the overstored container or a drop of container improperly installed on the hoist can cause quite

dangerous situation, resulting in fatal or serious injury.

Failure to have the maintenance personnel install the Chain Container may cause fatal or serious injury.

Before installation of the container, please also check the container capacity of the hoist and lifting height as shown on the

container.

Mandatory

Assembling

•Only qualified maintenance personnel or experts are allowed to assemble and disassemble the

electric chain hoist.

Assembly or disassembly of the hoist by incompetent personnel may result in death or serious injury.

Prohibited

■Installing a Chain Container

■Preparation for Assembling

• To facilitate mounting the chain container, hang the hoist body.

• Check that the stopper and the cushion rubber are attached to the third link from the end of the no-load side chain (the

side without the Bottom Hook).

■Assembling

The two types of the Chain Container are provided: canvas and steel

This manual describes the method to combine the canvas Chain Container with the body size of the electric chain hoist.

Refer to the separate “Mounting Manual of the Steel Chain Container" for the steel Chain Container.

•When storing the Load Chain into the Chain Container, put the end of no-load side chain first

and then store the rest of the Load Chain in order.

Failure to comply with these instructions may causes bodily injury or loss of property.

Mandatory

CAUTION

●Chain Container Seal

A seal in the right to indicate the hoist capacity and the maximum

lift is attached to the Chain Container. Be sure to check it before

installation.

Assembling Installing a Chain Container

DANGER

1) Install 2 container chains to the chain

container with socket bolts, plain washers,

and lever nuts.

2) Install the lug of the container on the chain

guide A at the bottom of the hoist with the

bolts and lever nuts.

3) Insert the socket bolt through a plate of

the Connection yoke, both end links of

container chains and the other plate and

fasten them with plain washers and lever

nuts.

1) Install 2 container chains to the chain
