SAFE OPERATION
4.3 SILENCING
The TMH hoist is fitted with an internal silencer; the noise output being less than 82 dB at one metre (this conforms to E.C. noise regulations).
TMH-37.5T
These types are fitted with a 2 stage silencer; first stage comprises of a single piece of felt, the second stage comprises of 5 pieces of nylon and
2 pieces of felt..
The life expectancy of the silencer correlates closely with the quality of air supplied.
The nylon pad may be washed with de-greaser and re-used once decontaminated.
Periodic examination of the silencer is not required, nor is it recommended (see below). As the silencer becomes contaminated a reduced
speed of operation will be noted. At this point the nylon silencer should be cleaned or replaced and the gauze silencer should be changed.
4.4
CHANGING THE SILENCER(S) - see parts list.
TMH-37.5T
Located on the end of the hoist above control valve is the exhaust cover. Remove the 4 x M6 screws to remove the perforated plate. Replace
2 x nylon and 1 x felt disc. Remove the 4 x M8 outer bolts holding the main exhaust cover on. Replace the 3 x nylon and 1 x felt pads.
The first stage silencer can only be replaced by Red Rooster Lifting trained personnel.
ADJUSTMENTS AND MAINTENANCE OPERATIONS
Before carrying out any work on the hoist the main air supply should be turned off and the residual air vented or the hoist run to dissipate
the air pressure.
Red Rooster hoists normally do not require any adjustment as the brake springs take up any wear and the load limiter and limits should not
need adjustment once set.
The lubricator should be checked and topped up weekly in normal use or daily when heavily used.
The load chain should be checked monthly for lubrication and oiled if necessary. Where the load chain is not lubricated for operational
reasons the chain should be inspected weekly as a dry chain can wear rapidly.
The top and bottom hooks should only be lubricated if required during checks.
The hoist gearbox is greased during assembly or repair and should not need greased during operation.
There are no hazardous substances in Red Rooster hoists.
