800D HOIST
MAINTENANCE AND SERVICE
For safe and consistent operation of this hoist a regular
program of preventive maintenance is strongly
recommended. Regular oil changes with the correct oil for
the ambient temperature conditions and an annual
inspection of the wear components will help ensure a long
life for your planetary geared products.
Maintenance Scheduling
The owner is to ensure proper inspection intervals, in
compliance with the API RP 2D Section 4 requirements or
the ANSI B30.5, 5-2.3, and will review hoist usage
categories on a periodic basis. A Qualified Inspector should
perform all maintenance and inspections.
• For hoists in occasional use, less than 10 hours per
month, API RP 2D recommends a pre-use inspection
and an annual 12-month inspection based on average
use over a quarter.
• For hoists in moderate use, more than 10 but less than
50 hours per month, API RP 2D recommends a pre-use
inspection, quarterly inspection, and an annual 12-
month inspection based on average use over a quarter.
• For hoists in heavy use, more than 50 hours per month,
API RP 2D recommends a pre-use inspection, monthly
inspection, quarterly inspection, and an annual 12-
month inspection.
Oil Level Maintenance
The oil level in the gearbox and brake housing be checked
and adjusted as part of the pre-use inspection. If the oil level
drops frequently or oil leakage is detected during an
inspection, maintenance should be performed to correct any
problems.
Oil Change Interval
The oil in the gearbox and brake sections is recommended to
be changed after first 50 hours of operation and every 1000
hours or 6 months of usage.
Hoist Brake Oil
Check Hoist Brake Oil
.
To check the hoist brake oil, remove the vent and fill plug
(Figure 11-1) and visually inspect the oil level. The maximum
fill capacity for the hoist brake is 0.23 liter (0.25 quart).
Drain /Add New Hoist Brake Oil
To drain and add new oil, remove the drain plug
(Figure 11-1), inspection plug and vent plug and drain the
brake oil. Reinstall drain plug and add fluid at the brake oil
vent hole until oil is at the bottom level of the inspection hole.
Install the inspection plug and the oil vent and fill plug. The
hoist brake fill capacity is 0.23 liter (0.25 quart).
NOTE: Brake lubricants are satisfactory for operation in
temperatures from -23° C to 66° C
(-10° F to +150° F). For operation outside this
range, contact Manitowoc Crane Care for
recommendations.
.
DANGER
Do not, under any circumstances, work at an elevated
height without using proper fall protection as required by
local, state or federal regulations.
CAUTION
The maximum fill capacity for the hoist brake is 0.23 liter
(0.25 quart). Over-filling the hoist brake can cause
damage to the hoist.
DANGER
Do not use EP type gear lubes in the brake section. This
may prevent proper operation and cause the load to fall
resulting in serious injury or death.
