Industrial - standard crane

 Crane Systems

Designed to meet our customer’s individual requirements in the most arduous industrial applications using modern design technology and quality modular system components. Jenmon manufacture a complete range of cranes from Overhead Cranes to Gantry Cranes. All cranes are conformed to Singapore Standard SS 497:2002 and DIN 15018.

Crane of unique specifications with up to capacity of 200 tons is available upon request.

 gantry Crane

 Overhead Travelling Crane

 Slewing Jib Crane

• The wall-mounted jib crane fitted onto a wall or a post, able to service a 180° section over a span up to 7 m
• The jib crane mounted onto a column, with partial rotation capability and totally independent from the building, anchored to the ground. It can service a work area of up to 270° over a span up to 7 m
• “TEMPLIER”, an articulated jib crane, easily handles loads from 50 to 1,000 kg, over a 5 to 2 m span, almost full circle, and practically no dead space (the articulated arm allows working around obstacles)
• The rotating jib cranes mounted onto a column is the most effecient: It handles from 500 to 5,000 kg. of load and over an area with a span up to 12 m

 Electric Wire Rope Hoists

New compact-design JMWH serial wire rope hoists offer outstanding quality and efficiency. Absolutely reliability is one of the most important features. JENMON introduced latest technology like infinitely variable speed control, braking energy feedback system, safety monitor into control system. All those innovations benefit our customers for greater reliability and efficiency and make JMWH wire rope hoist very competitive in the market.

 Hoist Machinery

Machinery design is based on FEM calculations for standard lifting gear allowing safe and reliable lifting of loads from 3.2 to 80 tons. Machinery has smooth and silent operation that extends the lifetime of the hoist.

Technical features:

• Gearbox made of aluminum
• Low-noise gearing design
• Life-time lubrication
• Double-surface DC brake

 Hoisting Motor

All hoist motors are equipped with imbedded bi-metallic thermal switch (or thermistors) in the windings to protect against overheating. Thermal sensors open an electric circuit when a predetermined temperature(~150℃) is reached. The thermal sensors used by JENMON meet VDE0631.

Prior to impregnation 100% of JENMON stators are tested. The test is executed according to DIN EN60204-1(VDE0113) for the following:

• Resistance between phases
• Inductance of phases by an impulse voltage
• Insulation between windings and PE with resistance measurement
• Breakdown voltage (high voltage 2500V tester)

Completed motors are high voltage tested according to VDE0530: (test duration time: 1 sec.)
UTest = (2 x UNom + 1000V) x 1.2 JENMON hoisting-Motors can be delivered with UL-Recognition  , valid for Canada (C) and the US (US).

 Hoist Gears

JENMON manufactures all gearboxes and gears. Sealed gearbox housings are made of aluminum. Gears (hoist and travel gearboxes) run in totally enclosed semi-fluid or oil bath lubrication, designed for the lifetime of the crane.

Precision flat beveled gear units in aluminum housings with case-hardened gears, high-grade surface treatment ensure high reliability and smooth running with minimum of maintenance.There are NO open gears to lubricate.

 Hoist Brakes

All hoist motors are equipped with DC magnetic disk brakes. The hoist motion brakes are adjustment free. The hoist motor and brake are designed and manufactured to work together so that the load will not slip at any point of starting or stopping of the hoist or lower motions.

Dual-disk electromagnetic brakes featuring automatic braking on power failure. Environmentally sound brake linings designed for approx. 1 million braking operations allow long maintenance intervals. The brake torque is at least 1.8 times higher than the nominal torque of the motor. Brake is fully covered and dust proof.

 Drum, rope and rope guide

The drum is turned from high quality steel tubing and has precision machined grooves for the rope, preventing rope overlap.

JENMON wire rope in standard hoist is a high quality 8-strand parallel closed rope. The inner and outer strands are closed in one operation. It has very high breaking load of 2160 N/㎡, good flexibility and long lifetime. This rope is suitable in all standard applications of material handling.

Standard rope guide is made of polyurethane which can minimize wearing of the rope. Heavy duty rope guide made form spherical cast iron is also available on request.
Rope pulleys are made from spherical cast iron.

 Cross travel drives

JENMON cross travel drives are designed to withstand unfavorable conditions such as low power supply or aggressive surroundings. The drives are operating in variable speeds as standard for maximum demands for movement and positioning of lifted loads.  Optimum speed, minimized swinging motion and sensitive positioning are combined to minimize cycle times.

Travel motors are equipped with DC magnetic disk brakes and the travel motor brake is adjustment free.
All drives are comply with relevant standards. Such as CE, VDE, DIN, UL/CSA, CCC etc., allow simple registration and approval of a crane system. Single speed and two speed drives are also available on request..

 Limit switches

Adjustable geared, self re-setting hoist and lower limit switches are provided as standard to prevent over travel of hook. Automatic cut-off of the lifting and lowering motions in the upper and lower limit positions.

 Safety Monitoring Unit

As an option the JENMON wire rope hoist can be equipped with a safety monitoring unit.
The latest FEM and ISO standards replaced the definition of the expected lifetime of hoists with the “Safe Working Period” (SWP). This refers to the actual working life of a hoist and not the time since installation. To comply with the standards, SWP values must be regularly monitored.

JENMON condition monitoring unit is the most practical, easy to use and sophisticated measuring device on the market.

It is a proven product, as it has been available since 2002. With this unit, all recording functions:
SWP, motor runtime, motor starts, number of overloads, overhear of hoisting motor and calculations are performed automatically.

In addition to the SWP calculation, it stops the hoist if overloading or overheating of motor occurs, and this results in increased safety and optimized maintenance activities.
With LED display all records can be easily checked when necessary.
