Mounting
The hoist body should be mounted from its suspension hook allowing the body to move in the
direction of the load chain pull and to hang in a straight line between the suspension hook and load
block during hoisting. Non compliance to this principle may result in severe damage to the
equipment. This is true if the hoist is used in the normal or inverted configuration.
Lubrication
The hoist gear reducer is lifetime grease lubricated needing no regular checking or maintenance.
Make sure the load chain is free from contamination or dirt and adequately lubricated with SAE 80
grade oil. Bottom block must hang straight and load chain must be free of kinks or twists.
Load Hook Throat Opening
ANSI B30.16-1993 recommends that the throat opening of the load hook be measured and recorded
prior to putting the hoist into service and that a gage be made to provide a quick visual inspection
for a bent hook as required by monthly inspections. See Section 4.
Power Connections
Make sure that power supply voltage is the same as that shown on the hoist nameplate and that fuses
or other current overload devices are provided to protect the power supply. The power
source/conductors must have sufficient capacity to maintain the voltage at the hoist at ±10% of the
nominal voltage under all operating conditions. Standard nominal voltages are 230 and 460V. Poor
voltage maintenance can cause motor overheating or sluggishness, and chattering or inoperative
motor brakes and controls.
A wiring diagram is included in this manual showing the identification of the power lead
connections. Refer to this wiring diagram prior to start up and/or any electrical work. If the diagram
has been misplaced you may obtain one from R&M upon request. Be sure to mention the serial
number of the unit.
Make sure the main disconnecting switch is off and locked in the open
position before making any electrical connections.
