2. SAFETY INFORMATION GENERAL SAFETY WARNING Indicated below are the structural and environmental requirements that must be checked by the user for guaranteeing safe use of the hoist: The user is responsible for the construction method used for the set-up structure, the related load capacity and the conditions of the suspension points arranged in the place of use. -
Page 14: Safety Warning For Use And Maintenance
SAFETY WARNING FOR USE AND MAINTENANCE The hoist can be used only and exclusively by authorised and qualified operator. The operational parameters of the electric chain hoist also encompass compliance with the predefined operating, service and maintenance requirements laid down by the manufacturer. Chain hoists may only be used when in an acceptable technical condition, in accordance with their operating parameters, by trained personnel in a safe and responsible manner. - Page 15 Before lifting, check for twists in the load chain. On single reeved chain hoist used in conjunction with head blocks and ground support systems, check for twists between the hoist and head block. Twisted load can result in a jammed chain and damage to the hoist. On double reeved units a twist can occur if the lower hook block has been upturned between the strands of chain.
-
Page 16: Safety Warning For Installation, Assembly And Disassembly
SAFETY WARNING FOR INSTALLATION, ASSEMBLY AND DISASSEMBLY The hoist must be assembled and disassembled only by authorized and qualified operator. The necessary qualifications for planning, assembly, disassembly, and activation, depend on the degree of risk and the location and type of job. Operator are required to provide current overload protection and grounding on the branch circuit section in keeping with the code. -
Page 17: Safety Warning For Residual Risks
Do not lift the load above people or do not leave hanging loads without the operator’s control and appropriate measures. Do not use the hoist outdoors or anywhere with water jets or environmental conditions without adequate protection. The use in explosive, aggressive atmosphere or with high concentration of powders or oily substances suspended in the air is prohibited. -

Page 42: Handling And Installation
4. HANDLING AND INSTALLATION When handling and unpacking the hoist you should use safe handling techniques. Electric chain hoists must be assembled by qualified personnel. Always refer to your local areas manual lifting directives, as well those mentioned in this manual. Should the electric chain hoist be destined for operation outdoors then it is necessary to use a protection cover to shield it from the effects of the weather. -
Page 43: Transport And Storage
It is advised to transport the electric chain hoist in its original packaging or a dedicated flight case. Before putting your EXE Rise hoist in storage make sure all components are dry Use flight cases with ventilation openings for all compartments... -
Page 44: Suspending The Hoist
SUSPENDING THE HOIST It is the user’s responsibility to ensure all hanging points, lifting hardware and control systems are inspected and tested prior before use. Cables must be placed in such a way that they do not come into contact with sharp edges and do not run the risk to be cut off or damaged. -
Page 45: Electrical Connections
EXE Rise hoists are factory set to be run with a voltage of 400 V AC. The DC hoist is fitted with a CEE 16A 6h 400VAC – 3PH +G black plug. plug as standard. The LVC hoist comes with a CEE 16A 4h 110VAC - 3PH +G black socket. -
Page 46: Use
Do stay clear of moving chains. Do ensure chain is lubricated at all times. Call your EXE Rise supplier if the hoist does not work properly. If damaged or worn parts are detected do not use the hoist. Seek assistance for service of the unit. -
Page 47: Lowering And Disconnecting The Load
Make sure the load has enough room to be free to move: no obstructions must be present along its travel. Make sure no other sound than the hoist can be heard Have a clear view on the load. Other wise use spotters with appropriate means of communication. They shall be in direct contact with the operator Select each hoist one by one and move it just that far that it is under tension and pick up the load Before moving the load check for twists in the load chain. -
Page 48: Limit Switch Setting And Replacement
LIMIT SWITCH SETTING AND REPLACEMENT Base rotary limit switch is an electromechanical device for low voltage control circuits (EN 60947-1, EN 60947-5-1) to be used as electrical equipment on machines (EN 60204-1) in compliance with the fundamental requirements of the Low Voltage Directive 2006/95/CE and of the Machine Directive 2006/42/CE. - Page 49 10.

Page 52: Inspections
6. INSPECTIONS For a correct and safe use of EXE-Rise chain hoist it’s important to carry out appropriate inspections and control. LITEC Italia recommended to comply with the frequency of inspections and follow the check reported in this chapter. INITIAL AND EACH ASSEMBLY INSPECTION AND CONTROLS The purpose of the following test and inspection is to ensure the hoist has been correctly assembled, installed, is not damaged and is safe to use. -
Page 53: Frequent And Periodical Inspection
FREQUENT AND PERIODICAL INSPECTION Here the term inspection refers to the visual examination of the hoist and its accessories. In order to keep a continuous and satisfactory operation inspection intervals must be determined by the individual application and are based on the type of service to which the hoist will be subjected and the degree of exposure to wear, deterioration or malfunction of the critical components. -
Page 54: Chain Inspection
TYPE OF SERVICE ITEM Severe a) All items listed in Table 8 for frequent inspections. Normal Heavy b) External evidence of loose screws, bolts, nuts. c) External evidence of worn, corroded, cracked or distorted hook block, suspension screw, bearings and dead end block and chain pin. d) External evidence of damage to hook retaining nut and pin. - Page 55 Particular attention should be paid to the condition of all bolts and safety components. If defects are discovered the hoist must be taken out of service and repaired immediately. TIP! To detect surface damage and deformations on the external surfaces of the links, use a piece of cotton fabric and pull the chain through.

these settings can vary easily by +/- 10%... The testing shall be performed with a suspended load of 120% of the maximum WLL. Other countries may have different regulations. However, clutch settings shall remain in between 110% and 160% at all times (EN14992-2). EXTRAORDINARY INSPECTION In case of extraordinary events which can jeopardise the safety of the working equipment, extraordinary testing must be carried out. -
Page 58: Maintenance And Repair
7. MAINTENANCE AND REPAIR Visual inspection and testing of the hoist and lubricating the chain are the only interventions that should be undertaken by the user of the hoist. All other maintenance, replacement, adjustment interventions that involve the opening of the hoist housing should only be carried out by LITEC Italia authorised service engineers. -

links are those links which stop on, resp. immediately at the inlet of the drive and reversing wheels at constant stroke when switching from lifting to lowering. These chain links are charged especially heavy by dynamic vibrations and have therefore to be lubricated carefully in shorter intervals. The choice of a suitable lubricant is dependent from the operating place and the existent environment conditions. - Page 60 a) Excessive load mechanical load clutch slipping. a) Refer to installation instruction in chapter 4. b) Open hoisting circuit-open or shorted winding in b) Check electrical continuity and 3) Hook lowers reversing contactor coil loose connection or repair or replace defective part. but will not broken wire in circuit;...
