PREVENTING DAMAGE TO THE LIFT
1. Exceeding the Capacity of the Lift
The load capacity rating is stamped on a metal serial number plate attached to the lift.
This figure is a net capacity rating for a lift furnished with the standard platform. The
Electrical Current Sensor (ECS) has been set to raise the weight, plus a small amount
for overload. Where conveyors, guarding, fixtures, etc, are installed on the lift after
leaving the plant, deduct the weight of these from the load rating to obtain the net
capacity. Loading the lift beyond its rated capacity is unsafe, will shorten the
operational life of the lift, and will void its warranty.
2. Fork Truck Traffic
The end user is responsible for preventing damage to the lift carriage and structure by
fork truck traffic, and fork truck loading & unloading (where applicable) by establishing
and enforcing safe and effective loading procedures, and by installing appropriately
sized barriers around the lift to minimize the likelihood of damage by fork truck impact
(i.e. pipe bollards, steel barriers, fencing, etc.). Operating the lift with a bent or
damaged carriage or guide beams is unsafe, will shorten the operational life of the lift,
and will void its warranty.
3. Jammed Loads
Permanent lift damage can result when loads that are placed on the lift are allowed to
hang over one or more edges of the carriage, and the carriage then sent to upper level
landings past obstructions/features which could potentially jam the overhanging load.
These features include shaft door openings, protruding landings, building joists/beams,
backstop panels, ductwork, pipe, etc.. Care should be taken to eliminate jams by:
a. Securing wheeled loads (pallet jacks, carts, racks, etc.) by braking or chocking
the wheels to prevent the load from “walking” towards & over the edge of the
carriage during lift travel.
b. Inspecting the loads placed on the carriage to make they are well within the
perimeter of the carriage before sending the load to another level .
c. Making sure that all snap chains (or drop bars – in some cases) are secured
across all loading/unloading sides prior to sending the load to an upper level.
d. Placing permanent visual aids on the carriage deck surface for fork truck
operators to know where to place loads within the perimeter of the carriage.
WHEN A CARRIAGE JAM OCCURS:
A jammed carriage may have damaged or broken the lifting chains or other critical
components that are supporting the carriage.
A. DO NOT attempt to free the jam by resetting the Electrical Current Sensor (ECS)
relay in the control panel and running the lift further up or down.
