The Sumner Eventer 20/25 Series Lifts are material handling lifts designed for elevating and lowering loads in various work environments. These lifts are not intended for hoisting or moving people and should never be used as personnel lifts.

Function Description:

The Eventer 20/25 Series Lifts are manually operated lifts that utilize a winch assembly to raise and lower a carriage equipped with forks. The lift consists of multiple mast sections that extend telescopically, allowing for significant lifting heights. Stabilizer legs are a critical component for ensuring stability during operation, especially when loads are elevated. The forks are reversible and adjustable, providing versatility for handling different load sizes and configurations. The unit is designed for mobility, featuring caster wheels for transport to and from job sites. A mast hold-down strap is used to secure the carriage during transport.

Usage Features:

• Operator Safety: Emphasizes reading the manual, understanding hazards, and proper use of safety equipment (hard hat, safety shoes, gloves). It strictly prohibits riding on the lift or using it to hoist people.
• Equipment Inspection: Requires pre-operation checks of moving parts, wire rope (cable), and overall condition. Damaged units or those not moving smoothly should not be used.
• Wire Rope (Cable) Requirement: A minimum of four complete wraps around the winch drum is required. Kinked, worn, frayed, or obstructed cables must not be used.
• Work Area Hazards: Operators must avoid high wind conditions, overhead wires, and obstructions. The unit should only be operated on smooth, level surfaces. Elevated loads should never be left unattended.
• Moving the Lift:
  • No Load: The lift is moved on its four caster wheels. It should be tilted into a reclined transport position with the carriage in the down position and the safety latch engaged.
  • With Load: Light loads can be transported over short distances (10-15 feet/4-5 meters) on the eight caster wheels, provided stabilizer legs are installed and locked, the load is in the lowest possible position, secure, and properly balanced, and the surface is level.
• Reversing and Adjusting Forks: Forks can be reversed 180 degrees by disengaging spring-loaded pins. They are also adjustable in width by sliding the fork arms along the tube and locking them into position with plunger rings. For minimum opening, the arms can be flipped over.
• Lifting and Lowering Loads: The winch is used to crank forks up or down. The winch handles should be cranked up about 1/4 turn to set the safety brake. Unstable loads must be balanced and secured.
• Storing Forks: Fork arms can be placed in a stored position by pulling the plunger ring, sliding the arm off the tube, rotating it 90 degrees, and sliding it back on until the plunger locks.
• Stabilizer Legs: Use of stabilizer legs is mandatory when raising loads. They are stored in pockets and inserted into mounting sockets, ensuring the locking plunger engages. The lift must be leveled using leveling screws until the bullseye bubble level indicates it is level, and all four base casters are off the ground.
• Mast Hold Down Strap: Secures the carriage in the lowest position during transport by engaging it with a safety latch loop on the fork assembly.
• Safety Latch Resetting: A spare spring latch is provided in the Operators Manual tube in case the original deforms from accidental winch cranking before disengaging the mast hold down.

Maintenance Features:

• Regular Inspections (Before Each Use):
  • Check cable for kinks, frays, and broken strands.
  • Ensure winch operates freely and cable is not tangled.
  • Inspect forks, legs, and base for bends.
  • Verify caster wheels move freely.
  • Confirm stabilizer legs slide freely and plunger pins lock.
  • Check leveling screws for easy turning.
• Recommended Inspection (Every 6 Months):
  • Inspect cable for frays and kinks.
  • Ensure winch works freely and parts are not loose or damaged.
  • Brake Inspections: Manually raise and support each mast section and carriage, then use a wooden block to test brake engagement. Brakes should engage before mast sections reach the bottom stop.
• Winch Maintenance:
  • Refer to winch assembly drawings.
  • Ensure both winch covers are on.
  • Check ratchet dog and brake ratchet for wear; replace if visible, lubricate holes with light oil.
  • Inspect gear teeth for wear; if none, brush with 50-wt. motor oil.
  • Proper brake adjustment (see troubleshooting).
• Cable Replacement: Detailed procedure involving lowering the carriage, removing the gear cover, unwinding the old cable, cutting the looped end, fusion welding the new cable to the old, pulling the new cable through, bolting the new cable to the top mast, threading the plain end into the drum, and winding the slack cable tightly.
• General Maintenance:
  • Check winch handles for wear/bends.
  • Inspect 3" roller wheels on winch and top mast for damage/smooth rotation.
  • Examine all bolts and nuts for tightness.
  • Ensure legs, forks, braces, and base are dent/damage free.
  • Check pulley covers for damage.
  • Verify load line is seated in all pulleys and pulleys rotate without obstruction.
  • Ensure stabilizer legs slide freely and plunger pins lock.
  • Check all roller wheels for free rotation.
  • Inspect masts and carriage hold-down device.
  • Raise mast sections to inspect for free, smooth sliding action; lubricate slideways with silicone.
  • Ensure all caster wheels rotate freely and are undamaged.
  • Inspect all plunger mechanisms and apply light grease.
  • Confirm all three mast covers are attached.
  • Check safety brake operation.
• Safety Brake Maintenance: The safety brake automatically engages when the unit is horizontal, preventing mast disassembly. A special tool (or a homemade rod) is required to release the brakes for disassembly.
• Troubleshooting Guide: Provides solutions for common issues such as masts not rising, slow load easing, winch malfunction, and safety brake issues. Emphasizes contacting Sumner Customer Service if problems persist.
